[SOLVED] P0C7C Code: Fixing Hybrid Battery Temperature Sensor ‘g’ Circuit Issue

The automobile fault code P0C7C indicates a problem with the hybrid battery thermistor. This can cause the engine light to turn on or the service engine soon warning light to illuminate.

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 this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour. It is important to address this problem promptly to prevent further damage to the hybrid battery system.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p0c7c fault code.

  • The symptoms of the automobile fault code p0c7c include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The fault code p0c7c can be caused by a faulty hybrid battery thermistor, battery smart unit, open or shorted harness, or poor electrical connection.

  • The fault code P0C7C 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 p0c7c, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0c7c, you need to check the possible causes mentioned above.
  • Inspect the wiring harness and connectors visually.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • The estimated repair time for this fix is 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p0c7c based on the estimated repair time of 1.0 hour include the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P0C7C fault code refers to the Hybrid Battery Temperature Sensor ‘G’ Circuit. This code indicates a problem with the temperature sensor located in the hybrid battery of the vehicle. The hybrid battery has three temperature sensors, and each sensor contains a thermistor that measures the resistance based on the battery temperature.

As the temperature increases, the resistance decreases, and vice versa. The battery smart unit uses these sensors to monitor the temperature of the hybrid battery and sends the information to the power management control ECU. The power management control ECU then uses this data to control the blower fan.

If the P0C7C fault code appears, it means there is an issue with the temperature sensor ‘G’ circuit.

This could be due to a faulty sensor, a wiring problem, or a malfunction in the power management control ECU. It is important to have this issue diagnosed and repaired to ensure proper functioning of the hybrid battery system.

What are the possible causes for the automobile fault code P0C7C?

If you see the engine light or service engine soon warning light on, the fault code P0C7C 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 the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
