93 Camry 3VZ-FE Sensor Identification

Hey everyone, I broke a sensor on the front of the block last night, working on replacing the front bottom motor mount. The sensor is located about 1 inch lower than the oil filter, and then to the left (passenger side) of the oil filter.

It's white plastic, and is connected to a loom that past the timing belt area, and has 1 plug capped off and connected to nothing, and the end of the loom was connected to this sensor. Plugs are white, sensor was white/ceramic.

After I tightened down the motor mounts, I went to crank the motor over thinking is must just be a oil pressure unit. But the car got ignition for 1 sec and then stopped getting fire and just turned over. I noticed than the Check Engine Light was on, so I cleaned up and went to bed. I didn't check to see if a "oil" light was on or if the car even has one (its new to me), I'll check that tonight when I get home. Regardless the CEL is now solid.

On 2nd though, about the car not starting now, I didn't think a oil sensor could do this, which is why I don't just assume this is what the sensor was, however, I suppose, I could have disconnected something when I was lifting the front of the motor (2" or so max), but since it was pivoting on the rear mount (like a clam shell opening, pivoting in the rear), I doubt anything near the firewall could have come undone.

I have to replace the sender regardless, but I would like to buy one before its too late tonight and I have the dealers closed. I called them, and I guess they don't have exploded views anymore, because telling him it was right there near the oil filter did nothing for him, he wanted a part #. (uhmm, the plug is okay, but the sender took a ratchet to it and is in pieces, I can tell its white, and plastic/ceramic, and I seem to remember the plug that connected to it was a single blade connector. And yes, its in front of the block, all to the left of the exhaust, I would say its right behind the oil dipstick tube if you wanted to get a how far left/right on the front of the block it is.

Thanks in advance,

Hunting the various forums for the person that goes, I know exactly what that is its ->..... :)

Is it possible for this when snapped in half, with top half still in plug and other half in motor, to get a CEL? Just curious, as I prepare myself for finding what else I did that I didn't intend to do.

There may still be other sources of the error code. Follow the instructions in the following threads and get the codes from the ECM.

1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
36 traction control found on JDM ecu's
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater
67 Catalyst low efficiency. (same as P0420)
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4
80 Exhaust Gas Recirculation insufficient flow detected
86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem

Thanks, that shows it exactly where I am talking. I appreciate it. I'll jump the diagnostic pins and count flashes later tonight.

I have another question, but it has to do with motor mounts that I have 75% changed already.
Will post another thread.

Thanks Again
