Hi guys, I got a 86 Camaro and it has a code 22. Low TPS voltage. I put in a new TPS taking my chance hoping that was it, but it doesnt seem to have fixed it at all. Also, the problem seems kinda intermittent, one second it can run with very little miss, other times its a bad miss. I found some not so good wires behind the left hand cylinder head. a broken one, and some other thinner wires. Can I have someone give me a diagram of the wiring harness?

I also checked for the 5v reference signal at the grey connector on the tps harness, and it was there. What can be wrong?!

Thanks!

Disregaurd the car in my sig, thats my old Z. This 86 has a tpi 305.

 

You should be able to find most of what you'll need here:

Did you also adjust the voltage setting on that new TPS when you installed it? The voltage should be between .48 to .62 VDC. You also will get a problem with binding if you overtighten the bolts (screws) when you install it.
