Trouble with tps

Recommended Posts

Hi all. I'm having trouble with my tps wiring. This is for an r32 skine with rb20det. I have code 17 coming up and my laptop is showing 4.97v Tps main. The code is for tps ground but i have checked my signal ground. (Black wire) i have a good connection at both sides of the plugs with tps connected. Also tried two different sensors. Same results. Any help would be appreciated. Thanks

Are you checking at the grey plug or black plug?  Did this problem just develop or is it a new install?  Can you have a look at the 5V out runtime and confirm that is showing near 5V.

Thanks for your reply! I am referring to the plug that is not fixed to the tps. The code is anv3 at ground. But when I test the ground, it checks out fine. This one has me stumped. Thanks for your help

The error "ANV3 at Gnd" means the signal wire is shorted to ground - nothing to do the ground wire. 

Can you answer my other previous questions:

If you clear the fault code, does it come back instantly?  If you look at the AN Volt 3 voltage in the analog runtimes, does the voltage change when you move the throttle?

Sorry, let me answer those questions. 1. Yes the problem just developed. 2. I will look at the run time values after work today. 3. If I clear code it comes back immediately.  4.voltage is froze at 5.00v. Can you tell me which signal wire coming from the two plugs is shorted to ground? It seems that I'm going in the wrong direction. Thanks again!

Ok, lets first adjust the error settings so they dont cause any confusion when troubleshooting.  Go to AN Volt 3 settings and set the error low to 0V and error high to 5V.

Have a look at the AN Volt 3 voltage in the runtimes and see what that shows, see if it changes with throttle open/closed and also see if it changes if you unplug the sensor.  I will wait for these results before giving next instructions.

Hello again and thanks for your help. I have located my problem.  It was the shielded signal wire making contact within itself, creating a short circuit. Tps works perfectly. Now to set up my vct solenoid. And tune the new engine.

Just followed this thread and had exactly the same issue as Pierre1357. Bad connection on a join and completely stopped the TPS working. All sorted now and time to tune!
