Code P2135 Dodge Description

The P2135 diagnostic trouble code (DTC) for Dodge vehicles indicates a correlation issue between the throttle position sensor (TPS) 1 and TPS 2. The TPS is a crucial component of the engine management system that monitors the position of the throttle valve and sends this information to the engine control unit (ECU). The ECU uses this data to determine how much air and fuel should be delivered to the engine for optimal performance. When there is a correlation problem between TPS 1 and TPS 2, it means that the signals from these sensors do not match, causing confusion for the ECU in adjusting the air-fuel mixture and throttle response.
