P18C9: Your Car’s Fuel Pressure Sensor Needs Attention
The P18C9 code indicates a problem with the gear position sensor in the transmission extension housing. The sensor has four wires and communicates directly with the Engine Control Module (ECM). The ECM supplies 5V to the sensor and receives a Pulse Width Modulated (PWM) duty cycle on two signal circuits that correspond to the linear and radial position of the magnet assembly on the shift shaft.
The sensor is used for Active Rev Matching and Active Fuel Management, and the ECM monitors it for an incorrect neutral condition.
