The throttle position sensor gives information to the ECM (Engine Control Module) about the position of the pedal determining the speed at which the driver is pushing on the accelerator pedal. It is located at the front driver side of the engine inside the bell crank assembly housing in between the cylinder head and batter.
If your Dodge Ram is having problems in idling, speed falls off suddenly, check engine light pops up you are getting codes P2121, P0121, P0122, P0123 then you may have a problem with your throttle position sensor.
This replacement TPS manufactured by Orion Motor Tech can be easily installed. In order to properly install the replacement sensor be sure the voltage of the TPS is set to 0.55v+ before locking in its position. Once set, turn the engine on and slowly push the accelerator pedal to the floor and back (only once) to make sure that the ECM learns the TPS calibration. More installation details are available upon request.
