How many wires does a TPS have?
How many wires does a TPS have?
The throttle position sensor (TPS) is a potentiometer located on the throttle body and attached to the throttle plate opposite the throttle linkage. It has three wires: battery voltage, 5-volt reference, and a signal wire.
How does the TPS work on a Dodge Ram?
Once you throw your Dodge vehicle in drive and accelerate the car, the throttle opens and the throttle position sensor immediately sends this change of the throttle angle as an INCREASING voltage signal to the PCM.
What are the DTCs for a Dodge Ram?
This article covers troubleshooting diagnostic trouble codes (DTCs) P0121, P0122, P0123 on the 5.2L and 5.9L Dodge Ram pick up (or van). NOTE: This tutorial only covers the throttle position sensor on the 1997 thru’ 2003 Dodge Ram pickup/van. For the 1992-1996 Dodge Ram pickup/van, see the following tutorial:
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.

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.
