hey guys, long time no see!

[outofstep]

well its been a few since i been back on here, but im baaaaaack lol, i got an ecu error code today on the way home from work, im on an obd0 setup, and i got 5 blinks, 5 blinks, then 3 blinks... i turned off the car while driving to reset the code thinking it was my o2 sensor, and the error didnt reset. then tried again a little further down the road and it went away for about 10 mins, then it came back. anyone know what i need to check/replace with that code?

im assuming it has something to do with : 3 & 5 Manifold Absolute Pressure (MAP) sensor or circuit.

cause thats the only 5 or 3 that i see, but just wanted to find out from someone that knows then to start replacing stuff that doesnt need it. thanks in advance guys!

ps. i have had an issue starting it, i've been having to push start it where ever i go atm, i have replaced: starter, battery, ignition switch so far and no luck, i think i have a power drain somewhere, because i'll have to pull the hot cable when i park to make sure i can get it started again., its been fun fred frinstoning my car everywhere, but thats the other issue i have been having, not sure if the two are related.

Blinks doesn't tell us much. Hard blinks or soft blinks? long pause or short pause? Codes go in order from lowest to highest. A Hard blink counts as 10, while each soft blink is 1. Therefore 5 soft blinks is code 5, 1 hard blink and 3 soft is 13, 2 hard blinks is 20 and you have hit the end of codes, the process repeats

[outofstep]

its 5 short, 5 short, 3 long then a pause then repeat

[Tony]

Can't be. Hard blinks come before soft blinks, codes go in numerical order. Its OBD0, there are only 20 codes, maybe a couple more, but I believe only 20.

[outofstep]

ok i think its just 13 short flashes

[Tony]

Code 13 would be 1 hard flash and 3 soft flashes.

obd0's just blink codes no long and short flashes like obd1

replace the vacuum line going to the map and check for 5 volts at the plug going to it with the ignition switch in the on position,

starting problem -first check- start your car for about 10 seconds and with the ecu flash any code, shut the car off, take out the key and see if the ecu is still flashing, if so you main relay is sticking and is draining the battery

[outofstep]

do you have a pic of where it would be? for the map sensor.

as for the starting issue, i dont normally get a code, does that matter? its been doing that for about a year now.

[readallen]

map sensor on the firewall



if the starting problem was to set off a code it would most likely be 16 or 20

[Tony]

OBD0 does have hard and soft flashes. I know because mine had code 10 and 14 for the longest time. The flashes are the same as reading OBD1 except you read them at the PCM instead of the CEL. He needs to learn to read the code before he starts checking and replacing things.

[outofstep]

ok as far as flashes, its for sure 13 short flashes, i have read flashes to know my o2 sensor was out before, i just was unsure what 13 flashes was.

i took it to work today, the code came up, when i got there i turned the car motor off, and the ecu did not continue to flash.

i'll check the map sensor when i get a chance, i dont have a voltometer to check for 5v, but i can at least inspect the vacuum lines. not sure what you mean about the 16 20 part.

[Tony]

Ok, then you must be working on some strange OBD0 PCM, one different than all the ones I have messed with. Because at most you will get 9 short flashes together, not 13. Code 13 on all the OBD0 hondas I have messed with is 1 hard flash and 3 soft flashes.

it time for the mod to brush up the faq then

"#1...... 4 x 100 is the bolt pattern for rims

#2...... for a gauge cluster swap... 88 - 89 are the same... 90 - 91 r the same and yes u can use the wagovan cluster

#3...... u can use 5w30 and 10w30 oil in ur car... honda recommends 5w30 tho

#4...... ECU Codes....

Code 1 (1 flash) Oxygen content

Code 3 or 5 Manifold absolute pressure

Code 4 (4 flashes) Crank angle sensor

Code 6 (6 flashes) Coolant temperature

Code 7 (7 flashes) Throttle angle

Code 8 (8 flashes) TDC position (top dead center) timing

Code 9 (9 flashes) No. 1 cylinder position (1.6L)

Code 10 (10 flashes) Intake air temperature

Code 12(12 flashes) No code 11 don't know why. Exhaust gas recirculation system

Code 13 (13 flashes) Atmospheric pressure

Code 14 (14 flashes) Electronic air control (EACV)

Code 15 (15 flashes) Ignition output signal

Code 16 (16 flashes) Fuel injector

Code 17 (17flashes) Vehicle speed sensor

Code 19 (19 flashes) No code 18 for some reason Lock up control solenoid valve

Code 20 (20 flashes) Electric Load "

well i can try to videotape it so you can see. its def 13 flashes

thanks for the image btw, i'll see what i can find. what was your next suggestion for the starting issue? I have to pull off the hot cable when i park, i have to push start it, even when trying to jump it, all that really does is charge up the battery so i can push start it. it doesnt turn over at all.

[Tony]

The FAQ is a sticky and easy to find. I even organized it for easy access to things.

Get a video if you can and I can tell you exactly what code or codes you have.

As for your starter issue, do you hear a click when you attempt to start it? not a click from the starter trying to engage, but a small click inside the car. There is a relay right above the hood release, this relay is for your starter. If there is no click, then your issue is somewhere between the relay and the ignition switch, possibly your clutch safety switch. If there is a click, the problem is possibly between your relay and starter. If you are getting signal to your starter solenoid switch, then the issue is either your battery cable coming to the solenoid switch, or the solenoid switch itself.
