P18C7: Your Car’s Fuel System Needs Attention

The P18C7 code refers to a fault in the gear position sensor circuit 2. The gear position sensor is a switching transistor mounted on the transmission extension housing. The sensor provides a PWM duty cycle to the ECM on two signal circuits that is proportional to the linear and radial position of the corresponding magnet assembly mounted to the shift shaft.

The ECM monitors the linear position signal 2 circuit for low and high voltage conditions. The vehicle uses the gear position sensor information primarily for Active Rev Matching and Active Fuel Management.
