★ Top Answer
When a Chevy Impala displays the P2138 error code, it indicates a malfunction that is preventing the throttle from operating correctly. The accelerator pedal position sensor comprises two sensors in a single unit, each connected to a low reference and a 5-volt reference circuit by the engine control module. Understanding that the accelerator pedal position informs the powertrain control module about the desired torque output is beneficial. If the issue originates from the throttle body and not just the sensor, the repair typically costs between $310 to $440, with labor accounting for $70 to $90 of the total amount.
