DTC P2135: Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
This DTC compares the throttle position (TP) sensor 1 input with the TP sensor 2 input. There are 2 TP sensors located on the throttle body inside of the throttle actuator control (TAC) module. The TP sensors are used to determine the throttle plate angle. The TAC module expects the output of the 2 TP sensors to follow the same linear path. If the 2 sensors report conflicting information to the TAC module, a DTC P2135 can set. The TP sensor is an integral part of the TAC module is not serviced separately. Installing a new TP sensor requires the replacement of the throttle body assembly. For additional information on the operation of the TP sensor and the TAC system refer to Throttle Actuator Control (TAC) System Description .
