Help! Code 32....cannot Read Tps
 
Well....I think I fucked up somewhere?!?!??!

I replaced my TPS. I then warmed up my car....then tried to adjust the TPS using the multimeter. Now, there is no signal readings though out the full adjustment range. I did ground the test wire.......I get code 32, solenoid valve switch. Has this happend to ANYONE???? Is it my ECU or Solenoid valve????

The car now runs stronger on accel, but bucks (alittle) around 2500 (decel) and has a little idle issue (hunting 600-900) when fully warm after a hard drive.

HELP!!!!!!!!!!!!

:mad:

Hmmm, I have the same symptoms as you, bad idle (although mine is worse in that the engine dies), it's just starting to buck around 2500, but after the secondaries kick in she accelarates hard and smooth (that's after the 3800 hump :mad: ).
I'm trying to get another ECU, see if that helps me.

Me too.....cannot find anyone local to assist....

Let me know your progress.....thanks for you post.

The Code 32 has nothing to do with the TPS - that's part of the ACV. Which also has nothing to do with how the car runs.

If you're having a bouncing idle, just mess with the TPS until you don't :). Try the 2-lights method - that works well for me.

You might have fried your ECU. I had this happen to me trying to adjust the TPS with a test light that I made with too high amperage bulbs. If you happened to cross wires or the probes of your multimeter accidentally while trying to get it adjusted it might have toasted a resistor or something in the ECU.

I had the same problem (codes indicating a problem with the ACV) and tried to chase down problems with the ACV and it ended up that the ACV's functionality is somehow dependent on the signal the ECU receives from the TPS. When I fried the ECU it ended up being because the signal from the TPS was not getting to the ECU to control the selenoids for the ACV.

I know that is a brief description of the problem, but if I were you....before chasing your tail, take the ECU out and open it up. Look for any "hot spots" on the circuit board where something might have gotten hot. My fry was pretty evident as it totally burnt off one end of the resistor that got overheated. I was able to fix mine by soldering in a new resistor. Once that was accomplished I was getting a signal at the TPS and got everything back online and adjusted properly. That was about a year ago and it is still running perfectly.

Thanks 91Vert....I will look into it this weekend. If that is the case, where did you get the resistor?
