Hello Lifers,Driveway mechanic, Frank is out with another fix!!! This little project includes some diagnostics and maintence. Frank tackles the removal and i Order Jeep Grand Cherokee Throttle Position Sensor Connector online today. Free Same Day Store Pickup. Check out free battery charging and engine diagnostic testing while you are in store. These are some of the most common reasons why the code appears. Defective throttle body. Unclean throttle body. A defective Throttle Position Sensor (TPS) Throttle position sensor improperly connected. Presence of corroded pins in throttle position circuit-related connectors. TPS circuit that is open or shorted. The P2122 code indicates that the powertrain control network (PCM) has detected an issue with the throttle position sensor (TPS), specifically that the sensor is running too low of a voltage. Most There are two types of throttle systems. They are drive-by-wire and drive-by cable. Most modern vehicles have drive-by-wire, where the throttle is controlled by a throttle position sensor attached to the gas pedal. When the throttle position sensor fails, it will either put your Jeep Grand Cherokee into limp mode or won’t respond. NQd761n. Changed the pcm, and no more problems.

Not sure if it changed on later years, but for the 2005 it was located on the throttle body: 3.7L V6 The Throttle Position Sensor (TPS) is mounted to the throttle body (1). 1. Remove air resonator tube at throttle body. 2. Disconnect TPS electrical connector. 3. Remove two TPS mounting screws (2). 4. Remove TPS. Common causes of the P2118 code for most vehicles include a failing throttle control motor, circuit issues, and a faulty throttle position sensor. On Ford vehicles, common causes include the TAC motor being damaged, the TAC motor harness circuits being short together, and obstruction in the throttle plate movement. 1592 posts · Joined 2013. #4 · Oct 12, 2017. The only "throttle body" a CRD has is for the EGR system, regulating how much EGR gases go back into the intake system. I don't think that would be the cause of your problems, since if it did fail, it has a spring that would cause it to fail in the open position.
