P18C2 Fault Code: Understanding The Description And Troubleshooting Steps
The P18C2 fault code refers to the internal mode switch in the Transmission Control Module (TCM).
This switch indicates the gear position selected by the vehicle operator. It consists of 5 separate hall effect switches, each supplied with a 9V reference circuit and a signal circuit from the TCM.
The voltage readings on each signal circuit will change depending on the gear selector position. The P18C2 code is triggered when the TCM detects that the internal mode switch ‘P’ circuit has an invalid voltage range of 0.70 – 0.96V for 2.7 seconds. This indicates that the circuit is stuck on an incorrect voltage range.
