Does a new throttle position sensor need to be calibrated?
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. The signal on the chosen pin should sweep from approximately zero to five volts as you move the throttle from fully closed to fully open.
How to test the TPS ( 1997-1998 ) Dodge Ram pickup?
1996-1998 TP Sensor Circuit Diagram (Dodge 3.9L, 5.2L, 5.9L). You’ll have the check engine light on your instrument cluster shining nice and bright for sure. TPS diagnostic trouble codes (DTC’s). P0121: TPS Voltage Does Not Agree with MAP. P0122: Throttle Position Sensor Voltage Low. P0123: Throttle Position Sensor Voltage High.
Why is my TPS not working on my Dodge Ram?
From surging and erratic idles to poor fuel consumption. Diagnosing the TPS is also finicky, as the many of its symptoms are relative to most of the vacuum and idle controls found on the vehicle. In most cases, a code will also accompany the failure of the TPS, and once that occurs, you can easily take care of the problem.
How does the throttle position sensor work on a Dodge Ram?
So here, in a nutshell, is how the throttle position sensor works when you crank and start your 5.2L, 5.9L Dodge: The fuel injection computer supplies 5 Volts and Ground to the throttle position sensor. 5 Volts is provided by the wire labeled with the number 3. Ground is provided by the wire labeled with the number 1.

How to test the throttle position sensor ( TPS )?
NOTE: It’s best to test the throttle position sensor (TPS) with the engine warmed up. This will increase the accuracy of your test result, especially if the TP sensor is failing intermittently. Place your multimeter in Volts DC mode and connect the red test lead to the ORG/DK BLU of the TP sensor harness connector.
