A P2138 code on a 2009 Chevrolet Impala indicates a problem with the throttle/pedal position sensor. Specifically, it suggests that the sensor signals are inconsistent or out of range, which can affect the engine's performance and throttle response. This issue may lead to reduced engine power or trigger the check engine light. It’s recommended to inspect the throttle position sensor and related wiring for faults.
The throttle position sensor is actually apart of the throttle plate actuator assembly and must be replaced as a unit.

The throttle position sensor (TPS) on a Chevy Impala is typically located on the throttle body, which is usually found near the intake manifold. It is mounted on the side of the throttle body and measures the position of the throttle plate, providing input to the engine control module. Accessing the TPS may require removing certain components for better visibility and reach, depending on the specific model year.
You will have to remove the gas tank and install a fuel pump module.
It is located in the air tube from the air cleaner to the throttle plate.
