Error Code P0C7C: What It Means & What To Do?

<<See All OBD Codes

Are you looking for information regarding the P0C7C error code? You are at the right place. Keep reading. The hybrid battery temperature sensor ‘G’ circuit is usually referred to the wiring issues in the vehicle. In order to monitor the temperature of a single battery cell, multiple sensors are used by the hybrid pack. If an improbable temperature is identified by one of the battery cells, then the P0C7C error code will be set. The high voltage system might get disabled if multiple sensors fail.

The HV battery has its temperature sensor in 3 of its location. As the temperature of the HV battery changes, the thermistor’s resistance which is built in each battery temperature sensor will also vary. The thermistor’s resistance will be high when the battery temperature is low. The HV battery temperature is identified by the battery smart unit with the help of battery temperature sensors and in turn, it sends the perceived value to the power management control ECU. The blower fan is controlled by the power management ECU, depending on the perceived results.

What causes this problem with the Hybrid Battery Temperature Sensor "G" Circuit?

• The battery smart unit might be defective.
• Damaged hybrid battery thermistor.
• There might be an opening or the hybrid battery thermistor harness might have a short circuit.
• The electrical connection of the hybrid battery thermistor circuit might be weak.

1. Hybrid Battery Temperature Sensor - One of the common symptoms that are linked with the failing hybrid battery temperature sensor is an engine that surges as you operate the vehicle. It helps to adjust the voltage of the system and if this process fails then you must replace it quickly.
2. Engine Wiring Connectors - The engine wiring connectors play an important role in connecting various components. Is the engine wiring connector broken? Get the replacement for faulty engine wiring connectors at affordable prices from PartsAvatar.
3. Battery Temperature Sensors - The consistent low battery voltage indicates that the battery temperature sensor is defective. Get it replaced to avoid the P0C7C error code in your vehicle
4. Electronic Pressure Regulator - Do you see any black smoke from the exhaust? Then the electronic pressure regulator can be damaged. Get it fixed as soon as possible.
5. Fuel Pump - The engine will not start at all or it will start to surge as you accelerate. This is one of the common symptoms for a faulty fuel pump which needs quick replacement so that the engine functions normally.
6. Battery Assembly - If there is a loss of electrical power, then the battery assembly might not function properly. Get the replacement for your damaged battery assembly from Parts Avatar.
7. Battery Control Module - Battery control module provides you with the information on charge state, battery health, and voltage that is easily accessible. If the battery control module is damaged, replace it quickly so that this information can be easily accessed.
8. VCT Solenoid - Is the engine oil dirty? Do you find the fuel economy to be less? Then it’s high time that you replace the defective VCT solenoid so that the P0C7C error code does not get stored in your vehicle.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P0C7C code by listing out some major symptoms. They are mentioned below as follows:

Common Symptoms

• You might find the engine light or else the warning light of the service engine turned on.

Want to correct the Trouble Code P0C7C? Read these points mentioned below:

• The damaged battery assembly has to be fixed.
• Damaged fuel pump needs replacement.
• The defective VCT solenoid needs fixation.
• Replacing the damaged battery smart unit.
• The damaged harness or the circuit of the hybrid battery thermistor needs to be fixed.

Here are some steps which you should follow in order to diagnose this fault code:

• Presence of white smoke indicates that the fuel is sent into the combustion chamber is not properly burnt.
• The white smoke can usually occur due to engine compression that is less, or because of the water that is present in the fuel from the fuel pump timing is thrown off as the fuel is starved of something from entering into the pump which is required for the pump to work accurately.
• The important thing with respect to P0C7C error code is to check the operation of VCT solenoid.
• The VCT solenoid valve can be stuck due to contamination.
• In order to perform the tests related to the VCT unit, you can verify the vehicle specific repair manual.
• If there is a burnt smell in the fluid, the transmission pan must be quickly removed and checked for any rubbles or clutch materials.
• Low pump pressure can take place due to blocks in hydraulic passages, a damaged pump, defective shift solenoids, and a broken electronic pressure regulator.
• Once you clear the codes, test drive your vehicle again to check if the error codes reappear.
• At times, it is best to leave these diagnostic codes to the trained professionals as there are many circuits involved.

Common Mistakes When Diagnosing The P0C7C Code

• Failure of the high voltage battery assembly.
• Damaged high voltage battery interface control module.
• An issue with wires.
