The P1C9D 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 it takes around 1.0 hour to fix.

To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related wiring harness and connectors.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1c9d fault code. Here are the symptoms to look out for:

  • The P1C9D 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, decreased fuel efficiency, rough idling, stalling, and difficulty starting the vehicle.
  • Additionally, the code may indicate issues with the transmission or the vehicle’s electrical system.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1C9D 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 P1C9D 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.

To fix the p1c9d automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p1c9d, 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 fault code is P1C9D. 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 P1C9D fault code will be between $75 and $150.

The P1C9D fault code is related to the Gear Shift Position Sensor 2 Circuit. This diagnostic checks the sensor’s output signal against normal operation threshold values. The sensor is located near the 2nd – 4th gear engagement actuator and detects linear movement of the piston.

A permanent magnet on the piston generates a saturation area in the sensor’s internal ferromagnetic core, which is transformed into an output position signal. 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.

What are the possible causes of the P1C9D automobile fault code?

If you’re experiencing the P1C9D automobile fault code, your engine light may be on. This could be due to a faulty Gear Shift Position Sensor 2, an open or shorted Gear Shift Position Sensor 2 harness, a poor electrical connection in the Gear Shift Position Sensor 2 circuit, or a faulty Transmission Control Module (TCM). To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for 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 P1C9D fault code?

To fix the P1C9D fault code, start by checking the possible causes, including a faulty gear shift position sensor 2, an open or shorted harness, poor electrical connection, or a faulty transmission control module. To visually inspect the related wiring harness and connectors, look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

Is a faulty Transmission Control Module (TCM) a common cause of the P1C9D fault code?

While a faulty Transmission Control Module (TCM) is listed as a possible cause of the P1C9D 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.
