The automobile fault code P18CA has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of P18CA will range between $75 and $150, depending on the repair time required.

The P18CA code indicates a problem with the gear position sensor in the vehicle. 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 information on the linear and radial position of the corresponding magnet assembly mounted to the shift shaft.

The vehicle uses this information for Active Rev Matching and Active Fuel Management. The P18CA code specifically indicates that the gear position sensor is not working properly.

What are the possible causes of the P18CA automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P18CA fault code. This code is usually caused by a faulty gear position sensor, an open or shorted gear position sensor harness, or a poor electrical connection in the gear position sensor circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P18CA fault code?

If you’re experiencing the P18CA fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few things you can do to fix it.
