The P1C86 automobile fault code is a common issue that triggers the Engine Light ON or Service Engine Soon Warning Light.

It is caused by a faulty PRNDL Display, PRNDL Display harness that is open or shorted, PRNDL Display circuit poor electrical connection, faulty Transmission Control Module (TCM), or faulty Shifter Lever Assembly. The importance of repairing this issue lies in the fact that it can lead to further damage to the transmission system. The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

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 due to the p1c86 fault code.

Here are the symptoms to look out for:

  • The P1C86 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 engine.
  • Additionally, the vehicle may experience transmission shifting problems, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1C86 automobile fault code can be caused by a range of issues, including a faulty PRNDL display and a faulty shifter lever assembly.

  • The automobile fault code P1C86 can be caused by a faulty PRNDL display, an open or shorted PRNDL display harness, a poor electrical connection in the PRNDL display circuit, a faulty Transmission Control Module (TCM), and a faulty Shifter Lever Assembly.

To fix the p1c86 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code P1C86, 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.

The fault code P1C86 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 P1C86 fault code can range from $75 to $150.

It is important to consider the repair time and the hourly rate when estimating the cost of fixing this fault code.

The P1C86 fault code is related to the Gear Shift Module (GSM) or Electronic Shift Module (ESM) in a vehicle. This code indicates that there is an issue with the Shifter’s PRNDL display operation or improper TRS messages from the Transmission Control Module (TCM). The specific problem identified by the P1C86 code is that the PRNDL Display Circuit Current is Out of Range.

This means that the current flowing through the circuit is not within the expected range, which can cause issues with the display and transmission control.

What are the possible causes of the P1C86 fault code?

If you’re experiencing the P1C86 fault code, your engine light may be on. This could be due to a faulty PRNDL display, an open or shorted PRNDL display harness, a poor electrical connection in the PRNDL display circuit, a faulty Transmission Control Module (TCM), or a faulty Shifter Lever Assembly. To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P1C86 fault code?

If you’re experiencing the P1C86 fault code, which is indicated by the engine light being on, you can visually inspect the related wiring harness and connectors to fix the issue. This fault code can be caused by a faulty PRNDL display, an open or shorted PRNDL display harness, a poor electrical connection in the PRNDL display circuit, a faulty Transmission Control Module (TCM), or a faulty Shifter Lever Assembly. To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors for damaged components, broken, bent, pushed out, or corroded connector’s pins.

Is a faulty Transmission Control Module a common cause of the P1C86 fault code?

A faulty Transmission Control Module (TCM) is one of the possible causes of the P1C86 fault code, which triggers the engine light or service engine soon warning light. Other possible causes include a faulty PRNDL display, open or shorted PRNDL display harness, poor electrical connection in the PRNDL display circuit, and a faulty shifter lever assembly. 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.
