Check Engine....

How do i check my codes???

I used the paper clip method on the 7M, is it the same for the JZ????
Also does any one have a code list for the JZ (if its diff)???

Thank you:biglaugh:

 

[Bigzavs]

same process as with the 7M, and same code list

Paper clip, same as the 7M. I'm sure Toyota wouldn't reinvent the wheel on the code numbers just because it's a 1JZ. Find a Toyota code chart and count the flashes.

SWEET thanks Guy's:biglaugh: :biglaugh: :biglaugh: :biglaugh: !!!

 

[87soup]

OOPS....

 

[BlackMKIII]

Oh god, what did you break now?

 

[87soup]

So... Code 42 seems to be the colprit, a speed sensor signal...

What the heck??? Should i bee concerned???:aigo:

 

[BlackMKIII]

Well, were you trying to get around the speed limiter or not? LOL.

Code 42: SPD signal is not input to ECU for at least 8 seconds during high load driving with engine speed between 2500 rpm and 4000 rpm.

Trouble Area: Open or short in vehicle speed sensor circuit, Vehicle speed sensor, or ECU.

My suggestion? Check your wiring.

Im sorry about the noob questions but what exactly does all that mean???:aigo:

And what does the wire look like??:1zhelp:

Who did your swap? Search around for an ECU pinout here on the board, you should find one.

A mechanic back in AZ:nono:... I will find that pin but what does this problem do to my car??? am i going to see performance gain with this fix:sarcasm:

 

[87soup]

Column "T" line 8: this is a soarer ECU but mine should be the same right???
I have a supra ECU

 

[BlackMKIII]

Hmm. Yeah, I think so. Check for continuity on that circuit. Maybe have someone drive while you're tapping between that pin and ground, to make sure you're getting a voltage change.

Uhm, I'll step aside and let someone take over from here. I got you going pretty well.

 

[87soup]

Thanks man...:biglaugh:

Any one down to help me out here??? Im getting closer....:sarcasm:

 

[Clint]

have you tryed clearing the codes then taking it for a drive and checking again? If it where me thats what I would do before assuming I have a problem with wiring harness... pull efi fuse and main relay turn car over that will clear the codes...

 

[Bigzavs]

just be glad its not a code 14

but ya, try resetting your ecu first, when i first got my mines it had 3 codes stored in it when i started the car the first time

 

[87soup]

Sounds like a plan!!!!!

I am having a problem pulling the codes the factory way. Can I jump pin W7(te1 check connector) and X24(e1 ground)? These should do the same thing, right?

 

[BlackMKIII]

I don't see why not.

 

[87soup]

I still have this problem and the ECU has been cleared but same code comes up every time....

How can i finally fix this???
Where is the sensor for this if any???
