  • The symptoms of the automobile fault code p0c86 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The fault code p0c86 can be caused by a faulty hybrid battery thermistor, battery smart unit, open or shorted harness, or poor electrical connection.

  • The fault code P0C86 can be caused by: a faulty hybrid battery thermistor, a faulty battery smart unit, an open or shorted hybrid battery thermistor harness, and a poor electrical connection in the hybrid battery thermistor circuit.

To fix the automobile fault code p0c86, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0c86, first, check the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p0c86 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P0C86 fault code refers to a problem with the Hybrid Battery Temperature Sensor ‘FG’ correlation. This fault code indicates that there is an issue with the correlation between the temperature sensors located in the HV (High Voltage) battery of the hybrid vehicle.

The HV battery has three temperature sensors, and each sensor contains a thermistor that measures the resistance based on the battery temperature.

The resistance of the thermistor changes as the battery temperature fluctuates. When the battery temperature is low, the thermistor resistance is high, and vice versa.

The battery smart unit utilizes these temperature sensors to detect the HV battery temperature and sends the information to the power management control ECU. The power management control ECU then uses this data to control the blower fan. The blower fan is activated when the HV battery temperature exceeds a predetermined level.

However, when the P0C86 fault code is triggered, it means that there is a discrepancy or inconsistency between the readings of the ‘F’ and ‘G’ temperature sensors.

This can lead to improper control of the blower fan, potentially causing issues with the HV battery’s temperature regulation.

It is important to address this fault code promptly to ensure the proper functioning and longevity of the hybrid vehicle’s battery system.

What are the possible causes of the automobile fault code p0c86?

If you see the engine light or service engine soon warning light on, the fault code P0C86 could be the culprit. This code is often caused by a faulty hybrid battery thermistor, a faulty battery smart unit, an open or shorted hybrid battery thermistor harness, or a poor electrical connection in the hybrid battery thermistor circuit. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the fault code p0c86?

If you’re dealing with the fault code p0c86 and your engine light is on, it’s time to take a closer look at the wiring harness and connectors. The possible causes include a faulty hybrid battery thermistor, a faulty battery smart unit, an open or shorted hybrid battery thermistor harness, or a poor electrical connection in the hybrid battery thermistor circuit. To fix the issue, visually inspect the wiring harness and connectors for any signs of damage. Pay attention to broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to check the “Possible Causes” mentioned earlier.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p0c86?

To resolve the fault code p0c86, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. These issues can cause poor electrical connections and lead to the engine light being on. By addressing these potential causes, you can effectively fix the problem and ensure the smooth operation of your vehicle.
