CEL code 0
 

my cel is throwing code 0 at me
thermostat ground is clean and secured.

i read somewhere on pgmfi.org that you can unjump a wire and check to see if the CEL is still on.

^its not the same as mine, but is this possible to do with my PR3 obd1 ecu??

which wires would i need to check?

also i pulled the plates off and visually inspected the boards and nothing seemed out of place

Re: CEL code 0
 

code 0 is bad ecu bruh if my mind isnt ****ing up lol

Re: CEL code 0
 

nope, your right. if you jump the connector and you get a solid light that doesnt flash. you have a bad ecu

Re: CEL code 0
 

Not necessarily... Regardless, it helps to search... from a previous thread still on the first page even.........


Here I will even repost the think...

i bookmarked that whenever you first posted it up. and ive done all the above, and still no prevail.

a buddy of mine has the guts of a p28 so i was going to see if it would get my car running, and if it runs decent, then i will make a trip to a friends shop and get a b16 ecu from him

Re: CEL code 0
 

Sounds like a good idea. Just wanted to be sure people understand a solid CEL doesn't necessarily mean its a bad ECU.

Re: CEL code 0
 

i just messed with the grounds a bit more.
changed a terminal connector on my + battery cable.

the starter definately has more "punch" but it still wont crank up.
at one point i did check for CEL codes and instead of 0. i got 20. ELD code.

so at least its showing some signs of life.
gonna tinker with it a little bit more.

i accidently had it in gear and it lurched at me about 8in. so thats a good sign.
probably gonna push start it tomorrow and see

Your car has been a grounding issue from the beginning!
If you were local I would happily stop by and replace all your grounds for free.
This thing is getting irritating!

Re: CEL code 0
 

How do you think I feel?! Lol its soo aggravating.
I also fiugred out why when I first got the car running my ckp code came on. :)

Here are the grounds I have and that I cleaned up
Trans to chassis - used one of the clutch cable bracket bolts to secure it.
Valve cover to core support

Thermostat ground has been cleaned
And I have my - terminal grounded to my shock tower but I think I'm gonna move it to the trans

Re: CEL code 0
 

He had his battery ground to the shock tower; the old saying is true - "You can't fix stupid."

Re: CEL code 0
 

Think he inherited it that way?
Had a ground going to a bolt under the seat too 0_o

Re: CEL code 0
 

HEY NOW!!! :P
we live and we learn from our mistakes.

im gonna hook the neg. cable to a different spot on the trans and see what that does.

Re: CEL code 0
 

hopefully it starts your car and ends this thread and the four others on this subject

Re: CEL code 0
 

Lulz gl op

Re: CEL code 0
 

moved the neg. battery cable to the trans as well. and nothing

Re: CEL code 0
 

Plug in -ANY- OBD1 ECU and turn the key to ON. (no need to try to start)
See if CEL turns off.
If CEL turns off, then your PR3 is toast.

Re: CEL code 0
 

thanks everyone here at H-T that have helped me.

got the hatch started today and it drives damn good now.
no longer in limp mode. still throwing codes for the o2 and IACV. but thats nothing compared to the troubles i have had lately.

Re: CEL code 0
 

so what was the problem? ecu?

Re: CEL code 0
 

ecu wasnt getting enough power.
the battery was somehow discharging. so i put the battery on a charger, and after about 30 mins. it cranked right up.
idles fine now. and drives even better

Re: CEL code 0
 

W...h...a...t...?...?...?...

Are you serious? Were these 10 different threads you started all over a battery? Funny joke I guess... you got us - just don't do it again.

Re: CEL code 0
 

Lmfao! I thought the parts store threw a good charge on it for ya... what kinda HELL???

Re: CEL code 0
 

If the cel stays solid when you jump the connector could that also mean you don't have any codes or does it only mean code 0?
