The P1C98 automobile fault code indicates a problem with the Gear Shift Position Sensor 1 or the Transmission Control Module (TCM). The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.

The cause could be a faulty sensor, open or shorted harness, poor electrical connection, or a faulty TCM.

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 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 p1c98 fault code.

Here are the symptoms to look out for:

  • The P1C98 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, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience transmission shifting problems, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P1C98 fault code can be caused by a faulty gear shift position sensor, poor electrical connection, or a faulty transmission control module.

  • The automobile fault code P1C98 can be caused by a faulty Gear Shift Position Sensor 1.
  • It can also be caused by an open or shorted Gear Shift Position Sensor 1 harness.
  • Another possible cause is a poor electrical connection in the Gear Shift Position Sensor 1 circuit.
  • Lastly, a faulty Transmission Control Module (TCM) can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1c98, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1C98, 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 P1C98 is a common issue in automobiles. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code is dependent on the repair time.

Most auto repair shops charge between $75 and $150 per hour. Therefore, the cost of fixing the P1C98 fault code can range from $75 to $150.

The cost may vary depending on the auto repair shop’s location, expertise, and the type of vehicle.

The P1C98 fault code is related to the Gear Shift Position Sensor 1 Circuit. This diagnostic compares the sensor’s output signal to normal threshold values. If the signal is out of range, the diagnostic will fail.

The sensor is located near the 1st – 3rd gear engagement actuator to detect linear movement of the piston.

A permanent magnet on the piston generates a saturation area in the internal ferromagnetic core of the sensor, 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 P1C98 automobile fault code?

If you’re experiencing the P1C98 fault code, your engine light may be on. This could be due to a faulty Gear Shift Position Sensor 1, 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 P1C98 fault code?

If you’re experiencing the P1C98 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few possible causes. These include a faulty gear shift position sensor 1, an open or shorted harness, poor electrical connection in the circuit, or a faulty transmission control module. To fix the issue, start by visually inspecting the related wiring harness and connectors. Look for any 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 P1C98 fault code?

A faulty Transmission Control Module (TCM) is listed as one of the possible causes of the P1C98 fault code, which is indicated by the engine light or service engine soon warning light turning on. Other possible causes include a faulty gear shift position sensor 1, an open or shorted harness, or poor electrical connection. 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.
