If the TPS voltage is reading too low or too high, you should get a code identifying one or the other condition.
Same thing for coolant temp sensor, IAT, MAP, CPS, right?
Say the aforementioned sensors have never been examined/replaced in you 4banger (mine's a '94 multiport FI) and it has 160k on the clock. Is it possible that said sensors are out of range, but not revealed as so with a code flash?
(Guess the shortest way to find out is to drain coolant, pull sensors, check the voltage and operating ranges on your own to be sure, maybe clean sensors and reinstall if everything is in range. Then tell yourself to save a Saturday and trust the codes next time :pirate:

You should get a code, along with poor performance.

yeah, normally a code would be thrown if the tps was out of range. But my jeep is an 89, and does not store codes. I just have to test each sensor... Sucks
