The P18C7 fault code in automobiles indicates a problem with the Gear Position Sensor. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty Gear Position Sensor, an open or shorted Gear Position Sensor harness, or a poor electrical connection in the Gear Position Sensor circuit.

The importance of repairing this issue lies in the fact that it can affect the vehicle’s performance and fuel efficiency. The repair difficulty is moderate, and it takes approximately 1.0 hour to fix.

To fix the issue, one 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.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p18c7 fault code.

Here are the symptoms to look out for:

  • The P18C7 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, and difficulty shifting gears.
  • Additionally, the vehicle may experience transmission problems, such as slipping or failing to engage properly.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P18C7 fault code can be caused by a faulty gear position sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P18C7 can be caused by a faulty Gear Position Sensor.
  • It can also be caused by an open or shorted Gear Position Sensor harness.
  • Additionally, a poor electrical connection in the Gear Position Sensor circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p18c7, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P18C7, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code is P18C7. The estimated repair time is 1.0 hour.

The cost of fixing the fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour. Therefore, the fixing cost of the P18C7 fault code will be between $75 and $150.

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.

What are the possible causes of the P18C7 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P18C7 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.
