The most common problem when a APPS sensor is failing is a "Dead Pedal." You will be driving down the road and hit the accelerator and NOTHING will happen. Your truck will not go. The most common codes associated with this problem are the 0121, 0122, 222 and 223. Another issue is a surging or a bucking and this oftentimes will not throw any codes.

This is an aftermarket (TIMBO) throttle position sensor for '98.5-'04 Dodge Cummins Turbo Diesel trucks and is not a factory-style replacement. This TPS is not application specific and works on trucks equipped with either a manual or automatic transmission.

You will reuse the original bell-crank plate that the throttle linkage attaches to with the one we carry. Only the sensor is replaced, and calibrated to a specific voltage range. It has proven to be a quality part that our customers have been happy with.

Detailed instructions are included that explain how to install and calibrate the throttle position sensor.

*Does not work on trucks with the APPS installed under the driver's side battery.

*Does not work on trucks with the Banks exhaust brake installed.

NOTE: If this part has been installed on your truck it is non-returnable.

Accelerator Pedal Position Sensor

My 1998 Dodge Ram 24v Cummins had the "Dead Pedal" syndrome (error code P0121). The new APPS sensor arrived within a few days, installed easily and solved my problem. Very happy!
