So I got the Wells 201 TPS from Autozone, installed it on a customer's car with MSPNP9093 and its a no go. Using a DMM, the readings are all over the place. The red/black wires measure a constant 3.8KOhm (check), but red/green and green/black measure random, non-ascending/non-descending values when opening/closing the throttle (fail). On the MS side, with the TPS wired in and all the mods done properly, the MS will read 255 ADC with almost any throttle opening and backing off the throttle, the ADC will slowly descent (like, 1 step per 2 seconds) down to 1. If I measure the voltage with the DMM when it is descending, it will drop down to 1 instantly.
DOA TPS?
