P18C4: Your Car’s Fuel System Needs Attention
The P18C4 fault code indicates a low 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.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P18C4 fault code.
