P0100
Mass or volume sensor or circuit
Possible Problems
MAF may be disconnected, or a wiring connection may be bad. MAF sensor may be faulty.
Reset the code and see if it comes back.
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken /frayed wires.
Unplug and reconnect the MAF wiring harness
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor
P0101
Mass or volume Circuit Range/Performance Problem
Possible Problems
Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value for more than 4.0 seconds.
Reset the code and see if it comes back
Inspect for the following conditions:
An incorrectly routed harness--Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components:
- The secondary ignition wires or coils
- Any solenoids
- Any relays
- Any motors
A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor.
A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 6-12 g/s at idle to 230 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
The barometric pressure (BARO) that is used in order to calculate the predicted MAF value is initially based on the MAP sensor at key ON.
When the engine is running the MAP sensor value is continually updated near WOT. A skewed MAP sensor will cause the calculated MAF value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet) of altitude.
A high resistance on the ground circuit of the MAP sensor can cause this DTC to set.
Any loss of vacuum to the MAP sensor can cause this DTC to set.
P0102
Mass or volume Circuit Low Input
Mass Air Flow (MAF) sensor or circuit. MAF circuit had lower than expected voltage (air flow).
Possible Problems
The MAF may be disconnected, or a wiring connection may be bad
The MAF may be dirty or otherwise contaminated (if you use an oiled air filter such as a K&N air filter, some of the oil may have made it's way onto the MAF sensor).
The MAF sensor may be faulty
The vehicle computer may be faulty (very rare)
reset the code and see if it comes back.
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.
P0103
Mass or Volume Circuit High Input.
Possible Problems
Mass Air Flow High (MAF) sensor or circuit. MAF circuit had higher than expected voltage (air flow).
The MAF may be disconnected, or a wiring connection may be bad
The MAF sensor may be damaged
The vehicle computer may be faulty (very rare)
reset the code and see if it comes back.
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.
P0104
Mass or Volume Circuit Intermittent
Possible Problems
Mass Air Flow High (MAF) sensor or circuit. MAF is producing incorrect air flow readings.
The mass air flow (MAF) circuit is incomplete (broken/frayed wire, etc.)
There is an air leak in the intake system
Reset the code and see if it comes back.
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.
P0105
The description of the expected voltages for the MAP sensor output (backprobing Terminal 2) in the Haynes manual is incorrect. The voltages listed are not the expected voltages,
they are the voltage drops expected from the reference voltage.
With the MAP connector attached and the ignition on and the vacuum line disconnected, measure the reference voltage by backprobing terminals 2 and 1. Measure the voltages at these same connectors while applying different vacuums at the port. If your reference voltage without vacuum is 3 volts (for example), then you should see the following voltages at these vacuums:
3.94 in Hg 2.5-2.7 V [3.0 V (reference voltage) minus 0.5-0.3 V]
7.87 in Hg 2.1-2.3 V (3.0 minus 0.9-0.7 V)
11.81 in Hg 1.7-1.9 V (3.0 minus 1.3-1.1 V)
15.75 in Hg 1.3-1.5 V (3.0 minus 1.7-1.5 V)
19.69 in Hg 0.9-1.1 V (3.0 minus 2.1-1.9 V)
Although your MAP may not exactly match what is listed above, the trend should be the same. I don't think there is anything magical about these absolute numbers, it is having a smooth trend that is important. There is bound to be some variation.
P0123
Throttle/Pedal Position Sensor/Switch A Circuit High Input
Possible Problems
Computer has detected that the TPS (throttle position sensor) is reporting too high a voltage.
Symptoms may include: Rough idle, High idle, Surging, or other symptoms may also be present
TPS not mounted securely
TPS circuit short to ground or another wire
Faulty TPS
Damaged computer (PCM)
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If engine is stumbling or hesitating, carefully inspect all wiring and connectors that lead to the TPS. More than likely the problem is with the TPS wiring.
Check the voltage at the TPS (refer to a service manual for your vehicle for this specific information). If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem.
Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc.

B. Diagnostics for P0446:
1. Inspect vacuum hoses and pipes between EVAP (Purge) VSV and Charcoal Canister for leaks.
2. Replace Vapor Pressure VSV and Canister.
NOTE :When performing diagnostics for an occurrence of a MIL "ON" condition, Diagnostic Trouble Code (DTC) P0441 may be result of debris in Evaporative Emission Control System. This may cause blockage of a vapor line, or a stuck VSV, as described in troubleshooting area of Repair Manual.
Possible Problems
Open or short in VSV circuit for vapor pressure sensor
VSV for vapor pressure sensor
Open or short in vapor pressure sensor circuit
Vapor pressure sensor
Open or short in VSV circuit for EVAP
VSV for EVAP
Vacuum hose cracks, hole, blocked, damaged or disconnected
Charcoal canister cracks, hole, or damaged
(P0446 is not normally associated with a loose or non-sealing gas cap. A loose or non-sealing gas cap triggers P0440 - see below diagrams)
1. Check the VSV connector for EVAP, VSV connector for vapor pressure sensor and vapor pressure sensor connector for looseness and disconnection
2. Check the vacuum hose between intake manifold and VSV for EVAP, VSV for EVAP and charcoal canister, charcoal canister and VSV for vapor pressure sensor, and VSV for vapor pressure sensor and vapor pressure sensor. Check these hoses for correct connection, looseness, cracks, holes, damage, and blockage.
3. Check voltage between terminals VC and E2 of ECM connector (4.5-5.5 V). (replace ECM if faulty)
4. Check voltages between terminals PTNK and E2 of ECM connector while applying vacuum to vapor pressure sensor (2.9-3.7 V).
If faulty, check for open and short in harness and connector between vapor pressure sensor and ECM. If ok at this point, replace vapor pressure sensor.
If voltage above is ok, Check VSV for EVAP. When ECM terminal EVP is grounded (ignition "ON"), Air should flow in pipe E (inboard on tube) on VSV and out F (outboard on tube) on VSV (Don't use high pressure air for this test). When EVP is not grounded, air does not flow in E and out F.
5. Check operation of VSV for EVAP. Remove VSV from engine. Check that there is continuity between the two terminals (30-34 ohms). If there is no continuity, replace VSV for EVAP.
Check that there is no continuity between either terminal and body. If there is continuity, replace VSV for EVAP.
Check that air does not flow from inner port (E) to outboard port (F).
Check that air flows from port E to F when you apply battery voltage across terminals. If no air flows, replace VSV for EVAP.
6. Check the vacuum hose between intake manifold and VSV for EVAP, and VSV for EVAP and charcoal canister. Check as above.
7. Check for open or short in harness and connector between EFI main-relay and VSV for EVAP and ECM. If faulty, repair or replace harness or connector. If ok, check and replace ECM.
8. Check VSV for vapor pressure sensor. When ECM terminal TPC is grounded (ignition "ON"), Air should flow in pipe E (inboard on tube) on VSV and out F (outboard on tube) on VSV. When TPC is not grounded, air flows out G (outside of connector).
If ok, check and replace charcoal canister.
If not functioning correctly, check function of VSV for vapor pressure sensor. Remove from engine.
Check that there is continuity between the terminals (33-39 ohms). Replace the VSV if there is no continuity.
Check that air flows from port E (inboard in tube) to port G (side of connector).
Check that air flows from port E to port F (outboard in tube) when battery voltage is applied across terminals. Replace VSV if function is incorrect.
9. If good, Check the vacuum hose between charcoal canister and VSV for vapor pressure sensor, and vapor pressure sensor and VSV for vapor pressure sensor - check as above.
11. Check for open and short in harness and connector between EFI main replay and VSV for vapor pressure sensor and ECM.
To clarify the scope of the P0440, P0441 and P0446 DTCs, here are reproductions of part of the Diagnostics section of a 2000 Toyota Repair Manual.
Note that the P0440 reflects uncharacteristic pressures in the components within the dotted line only. The same goes for the diagram of the components within the dotted line for the P0441 and P0446 DTCs.
Only the P0440 code will show a problem with pressure (or lack of pressure) within the fuel tank. The fuel tank cap is only cited as a potential source of the DTC in P0440, not in P0441/P0446.
Note that the potential problems are listed with the most probable culprit on the top of the list.
P0770 Shift Solenoid E Malfunction
Solenoid E (SL) is the torque converter lock-up solenoid. If the torque converter is a little slow locking up, it will set this code. May only be a one-time thing owing to a small particle of something getting jammed in the solenoid. The code may disappear by itself.
If it doesn't right away, check out the color of your tranny fluid. If it is pretty much red or brown and smells ok, then flush the tranny and see if that gets rid of the code. If not, pull out some fluid and add a bottle of Seafoam Trans Tune and run it for 1 or 2k miles. Then flush the transmission again. Check if the code is gone.
If this problem persists, I've been told you'll have to replace the E-solenoid.
There is a Service Bulleting (EG006-00) issued for '00 Siennas on this problem. They get a new torque converter to fix the problem permanently.
The following discussion was submitted by csaxon:
The ECM uses signals from throttle position sensor, airflow meter and crankshaft position sensor to monitor engagement of Torque Converter Clutch (TCC).
The ECM compares engagement condition of TCC with lock-up schedule in memory to detect MECHANICAL trouble of lock-up solenoid, valve body and torque converter. A P0700 trouble code is set when TCC lock-up does not occur during appropriate speed, or lock-up does not release at appropriate speed.
Possible causes are:
* Solenoid is stuck open or closed.
* Valve body clogged or valve stuck.
* TCC malfunction.
There are simple electrical tests to check the solenoid and plunger but the transmission pan must be removed to gain access.
As Brian suggests, if you haven't had your system flushed or changed in awhile it may help but I'm not sure that's cheaper than actually removing the pan and checking the solenoid.
The Toyota service tech can check the system without pan removal with his analyzer.
P0793 "Intermediate Shaft Speed Sensor A"
Thanks to hk rogers for the following information:
Recently had a repair on a 2009 Toyota Matrix 2.4L with a CEL P0793 "Intermediate Shaft Speed Sensor A" code that I had a lot of difficulty finding good information on. Thought I'd post the repair info here to help out others in the future.
1. I pulled the codes at Autozone and they told me I needed a Transmission Speed Sensor (Part #SU40465) however they were unsure the location and that there were 2 sensors and no way to tell which is bad.
2. Took code to Toyota Dealership and they tried to sell me an ABS Wheel Speed Sensor for $250.
3. After digging through a variety of online resources I suspected Autozone was correct, ordered the part and set out to find the sensor.
4. On the 2.4L Matrix both sensors are located beneath the Air Filter box. Disconnect the intake hoses, pull off the box, loosen the three bolts holding on the box and voila you have access. The "A" Sensor is located directly beneath the air box in a vertical position. The other Sensor ("B" I assume) is a little further forward and angled toward the back of the battery. I would imagine the battery would have to be removed for ease of access.
5. 1 12mm Bolt and a rather sticky wiring harness later and you're in business.
P1780 PNP Switch Malfunction
Easiest solution: It is common on Camrys to have problems with the loom of wires inside the trunk, attached to the driver's side trunk hinge. That loom is subjected to a lot of flexing, each time the trunk opens and closes. Eventually some of the wires inside that loom fray and break. Open that loom of wires and look for frayed or broken wires. Repair what you find. For pics see
here.
