Abstract

Error code P2115 indicates that the Engine Control Module (ECM) has detected the throttle position sensor D is stuck or not performing within the expected minimum stop range. This can cause poor acceleration, rough idle, or your vehicle going into limp mode. The fix typically involves inspecting and cleaning the throttle body, checking sensor wiring, or replacing the sensor.
