Just put in the new motor, but this issue has been lingering for quite some time, dating back to the tired 305.

TPS will show normal at idle, and when setting it... .54v or around depending on where I set it at...

But when going to WOT, or simulating WOT, it only gets to 1.27v. Still though would go to Cell 15 (WOT) when the 305 was in, and go to the PE tables...

dumbfounded, and I am going to check the readings via multimeter today...

All numbers up to now are from an Autoxray scanner, but what the scanner tells you is what the ECM actually sees, so i doubt the numbers will be different from a multimeter...

Thanks guys.

 

Make sure your actually getting the 5v reference to the sensor.
