TPS keeps going Bad?
I have a 94 F150 with a 5.0 4wd extended cab? Can anyone tell me why the tps sensor keeps going bad? I have put 3 in in a year so far? Only codes are EGR valve and excessive torque converter slip. Tranny does slam intermittently? Any help greatly appreciated!!!! Thanks in advance!!

I would be inclined to test the TPS. I would ohm it out first. Then check voltage for closed and then watch for voltage spikes or dips from closed/stopped voltage to full WOT.
And because the TPS is so very important to electronic transmission, I only use OEM, Motorcraft. Same would hold true for Dodge, GM and so forth. Its usually not worth my time to justify a few dollars saved if I cant rule out that being part of the problem.

There is a good reason that the Motorcraft one costs 4 times as much. You do get what you pay for.
