"TPS" is your throttle position sensor located on the right side of your throttle body (if you are facing your engine) the function of the tps is to send imput to your pcm (power control module) by the movement of the throttle plate at idle/part throttle/wide open. the pcm will adjust air/fuel mix/egr functio/timing of spark based on tps imput by way of voltage signals. you can check for a bad tps sensor by using a voltmeter and back probing the tps connector. there are 3 wires with the connector tange facing up, the 3 wires are sensor ground (the wire closest to you) the middle wire is the sensor signal wire and the wire furthest away from you is the 5v supply wire. turn ign key to "on" (do not start engine) voltage should be between 0.2-1.4v with probes still inserted into the plug, slowly turn throttle pulley toward wide open throttle, youe readings should slowly rise to about 4.5v - IF NO VOLTAGE PRESENT- check wiring harness for supply voltage (around 5v) ground (0.3v) if both supply voltage and ground voltage present AND no output voltage tps FAULTY TPS. remove/replace tps. if voltage values exist, but are less than what they should be, look for problem with wiring harness, or bad pcm. my other thoughts are partially plugged fuel filter/pressure sensor, or a vacuum leak gremlin somewhere.

The tps is a ******* 20$ item, buy a new one put it in because it is two torx screws right on top of the engine. The tps wont set a code because range is inbetween 1 n 5 volts, a faulty tps will wear into a certain spot due to driving habit. I.E you never tromp on your truck and it wears into the normal driving rpm. Easiest way to check is replace, known to go bad as well as IAC sensor. both items under 50$. ALSO drill hole in both doors as ice is known to build up in bottom of door, i would drill as close to the hinge as possible due to gravity. SIgn is when u open ur door after rain water comes out of end of the door
