Need help with Code 51

newtome · 04-14-2006, 02:18 AM

Hi
I'm getting a code 51 when I step on the gas and when I let it off the code goes away.I can't drive the car at all it goes into save mode.Ita a 89 supra turbo.The throttle position senser tests out good.I'm lost and ready to pull the rest of the little hair I have left out.Any help would be great.Thanks

Did you remove the diagnostic jumper(paper clip) under the hood from the diagnostic block when you last checked codes?

I've pulled the fuse to reset the ecu and started the car and it runs the same I've done it with the jumper and with out the jumper and it does the same.with the jumper in it will flash code 51 only when I try and give it gas and when I let off code 51 goes away.

I would try to adjust your TPS as per the TSRM on page FI-103 and see if that makes it go away..

I've done that three or four times and it is still the same.I've checked the tps with the ohm meter also and it shows its good.I've checked the wires all the way back to the ecu just to make sure that they were good also.
