The P1C9C automobile fault code indicates a problem with the Gear Shift Position Sensor 2 or the Transmission Control Module (TCM). The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.

The cause of this issue could be a faulty sensor, an open or shorted harness, or a poor electrical connection.

The importance of repairing this problem lies in the fact that it can affect the performance of the transmission.

The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins. The repair time is estimated to be around 1.0 hour. To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related components.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1c9c fault code. Here are the symptoms to look out for:

  • The P1C9C fault code in automobiles 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, engine stalling, rough idling, decreased fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may experience transmission shifting issues, and the engine may emit unusual noises or vibrations.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1C9C automobile fault code can be caused by a faulty gear shift position sensor, open or shorted harness, poor electrical connection, or a faulty transmission control module.

  • The automobile fault code P1C9C can be caused by a faulty Gear Shift Position Sensor 2.
  • It can also be caused by an open or shorted Gear Shift Position Sensor 2 harness.
  • Another cause can be a poor electrical connection in the Gear Shift Position Sensor 2 circuit.
  • Lastly, a faulty Transmission Control Module (TCM) can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1c9c, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1c9c, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for 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 automobile fault code P1C9C 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 cost of fixing the P1C9C fault code will depend on the hourly rate charged by the auto repair shop.

The P1C9C fault code is related to the Gear Shift Position Sensor 2 Circuit. This diagnostic compares the sensor’s output signal to normal threshold values.

The sensor is located near the 2nd – 4th gear engagement actuator to detect linear movement of the piston.

The sensor provides an output signal with Pulse Width Modulation (PWM) at a fixed frequency and duty cycle proportional to the piston position of the actuator. If the signal is out of range, the diagnostic will fail and trigger the P1C9C fault code.

The code indicates that the Gear Shift Position Sensor 2 Circuit is low.

What are the possible causes of the P1C9C automobile fault code?

If you’re experiencing the P1C9C fault code, your engine light may be on. This could be due to a faulty Gear Shift Position Sensor 2, an open or shorted harness, a poor electrical connection in the circuit, or a faulty Transmission Control Module (TCM). To fix the issue, check the possible causes listed above, visually inspect the wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P1C9C fault code?

To fix the P1C9C fault code, start by checking 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 will help identify any issues with the Gear Shift Position Sensor 2 harness, circuit connection, or faulty Transmission Control Module (TCM).

Is a faulty Transmission Control Module (TCM) a common cause of the P1C9C fault code?

While a faulty Transmission Control Module (TCM) is listed as a possible cause of the P1C9C fault code, it is not a common cause. The more likely culprits are a faulty Gear Shift Position Sensor 2, an open or shorted harness, or poor electrical connection in the circuit. To fix the issue, it is recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
