Code P2135 Jeep Description

The P2135 diagnostic trouble code (DTC) for Jeep vehicles indicates a Throttle Position Sensor (TPS) 1/2 correlation issue. This means that there is a discrepancy between the signals sent by the two TPS sensors in the vehicle, causing a misalignment in the throttle position data. The TPS is a crucial component that monitors the position of the throttle valve in the engine. When the TPS 1 and TPS 2 signals do not match, it can lead to incorrect fuel delivery and air-fuel mixture, resulting in drivability issues and potential damage to the engine over time.
