anyone know what the MAX voltage should read at the tps at WOT ?

 

It can't read more than 5v, because that is what is fed to it. Something close to 4.7v is about average.

 

Thanks shoebox....

so, would that be about 1 volt at idle ?

and , any known history of these cars having tps problems ?

 

The TPS actually seems to be pretty reliable from what I have seen.

 

tps should be about .5 or .6 at idle, anything less than i think about .4 would throw a low tps voltage code, my tps started reading really low, idle was about .3, the car wouldn't idle under 1100 and the SES lit up, changed it and no more problems! it was like 22 bucks at pep boys.
