P18C5: Your Car’s Fuel Pressure Sensor Needs Attention

The P18C5 fault code indicates a high voltage condition in the gear position sensor circuit 1.

The gear position sensor is a switching transistor mounted on the transmission extension housing.

The sensor interfaces directly with the Engine Control Module (ECM) and provides a Pulse Width Modulated (PWM) duty cycle to the ECM on two signal circuits. The ECM monitors the radial position signal 1 circuit for low and high voltage conditions. The gear position sensor information is primarily used for Active Rev Matching and Active Fuel Management.
