Guide To P0C83 OBD Error Code Solutions

<<See All OBD Codes

What are the symptoms for P0C83 error code? Is the battery smart unit malfunctioning? Then there is a high chance that the P0C83 error code is stored in your vehicle. The hybrid battery temperature sensor ‘H’ circuit low is commonly referred to the wiring issue in the vehicle. By using multiple sensors, the hybrid battery pack will observe the temperature of each battery cell. The P0C83 error will be set if at least one of the battery temperature sensors finds an unlikely temperature. If the failure of multiple sensors occurs, then the high voltage system will be disabled.

The battery temperature sensor is made available in 3 locations of the HV battery. Based on the changes in the HV battery temperature, the thermistor’s resistance that is built in each battery temperature sensor will vary. Higher the resistance of the thermistor, lower will be the temperature of the battery. On the other hand, if the resistance is low, the temperature will go high. The battery temperature sensor is utilized by the battery small unit to find the temperature of the HV battery. After this, the value that is noticed is sent to the power management control ECU. The power management control ECU will then operate the blower fan depending on the results of detection.

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

• The hybrid battery thermistor might be defective.
• There might be an opening in the hybrid battery thermistor or the circuit might be shorted.
• The electrical connection of the hybrid battery thermistor circuit might appear to be weak.
• Battery smart unit might be malfunctioning.

1. Hybrid Battery Temperature Sensor - The battery light will start illuminating if the hybrid battery temperature sensor is faulty. It’s good to replace the damaged hybrid battery temperature sensor quickly so that the engine functions normally.
2. Hybrid Battery Pack - A damaged hybrid battery pack will start emitting strange noises from the engine. It is best to replace the damaged hybrid battery pack.
3. Engine Wiring Connectors - High temperature can cause the corrosion of engine wiring connectors. Changing the damaged engine wiring connectors is essential so as to avoid the P0C83 error in the vehicle.
4. Battery Temperature Sensors - A malfunctioning battery temperature sensor can cause voltage fluctuations. Get it replaced as soon as possible.
5. Battery Assembly - A faulty battery assembly will produce cranking noise. Replace the faulty battery assembly with a new one.
6. Battery Control Module - If the battery control module is damaged, then the fuel economy will be reduced. Replace or repair it as soon as possible.
7. Battery Smart Unit - One easy way to avoid the P0C83 error code in your vehicle is to replace the faulty battery smart unit as it will give rise to the illumination of MIL and causes further performance related issues.
8. Powertrain Control Module - The engine behaviour which is erratic indicates that the PCM is faulty. Repairing the faulty PCM can help you to get rid of the P0C83 error code.
9. Fan Blade - If the motor of the fan blades is damaged, then the fan blades won’t turn as needed. Repairing the damaged fan blades can help you to fix the issue.
10. Engine Pulley - As you start the engine, you will notice the squealing of the belt, if the engine pulley is bad. Changing the bad engine pulley can help you to get rid of the P0C83 error code.
11. VCT Solenoid - The VCT solenoid might malfunction if the engine oil is dirty. Repair the faulty VCT solenoid so that the vehicle functions normally.

For us our customers are everything, and that’s why we will help you to diagnose P0C83 code by mentioning some important symptoms below:

Common Symptoms

• Either the warning light of the service engine or the engine light will remain on.

Have a look at some ways with which you can correct the P0C83 code:

• The malfunctioning battery smart unit needs replacement.
• The broken or the damaged harness or circuit of the hybrid battery thermistor has to be replaced.
• Replacing the defective hybrid battery thermistor.

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of hybrid battery temperature sensor, brake pads, electrical connector, PCM, fan blade, engine pulley, VCT solenoid, brake rotors, hydraulic cylinder, brake cables, and a lot more. We are sure that now all your issues would be resolved.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• A specialized CAN scanner can help you to show pin values and the operation of the control module without involving any risk.
• If each of the circuits and sensors are good, then you must check if the transmission is in good working condition. In one such case, you can expect the PCM to be faulty but it is very rare and will require reprogramming or replacement.
• The affected control modules will receive the signal so that they can use the data to perform several other tasks.
• It is very rare to find the failure of the individual control modules.
• As you put your foot on the brakes of the car, you can likely expect your car to slow down or it might even come to a stop position.
• The amount of power that is applied on the brake pedal by your foot is aided with the help of hydraulic pressure.
• The force from your foot will engage with the piston and caliper where the brake pads are fixed (bonded abrasive and heat resistant metal or ceramic) so that you can apply pressure on the rotor.
• The OBD -II error code P0C83 is usually related to the vehicle which is electronically controlled by an automatic transmission, where 3-4 shift solenoids hold responsibility for actuating the hydraulic circuits so that the clutches or bands will get started which is responsible for changing the gears inside the automatic transmission.

Common Mistakes When Diagnosing The P0C83 Code

• Damaged high voltage battery assembly.
• The electrical wires might be problematic.
• Broken high voltage battery control module.
