Throttle Position Sensor, "Huh"? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1988 C2500 5.7 TBI -GMC.... I replaced the TPS a few months ago ( a mechanic thought it may be bad)... My Check Engine Light, lit up, but turns off after 40mph.

Code 22 - Error Signal low..... I replaced it with the old one ( for today).. The Check light is doing the same thing with old one, but worse than before ( it didn't do that before)

I will get a Delco this time... BUT, could there be another cause for a "low signal"????

I also noticed the bolt holes are actually slotted. Is there an adjustment by tilting it a bit? Huh??
