P0C43 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0C43 can be elucidated as Hybrid Battery Pack Coolant Temperature Sensor Circuit Range/Performance. The cooling air would start flowing into the inlet on the right of the rear seat and would then travel through an intake duct to the battery blower assembly on the right surface of the luggage compartment. The cooling air would travel through an intake duct which would then connect the battery blower assembly to the upper right surface of the HV battery assembly and then it would simply flow to the HV battery assembly.

Are you tensed because the P0C43 fault code is flashing? We have everything which you need and at equitable prices. For us our customers are everything and that’s why we promise that you will never regret your decision. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Hybrid Battery Pack Coolant Temperature Sensor Circuit Range/Performance?

• Some issues related to the hybrid battery pack coolant temperature sensor
• Unlocked hybrid battery pack coolant temperature sensor harness
• Unsatisfactory electrical connection in the hybrid battery pack coolant temperature sensor circuit

1. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times, a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
2. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration. Buy high grade PCM online from us.
3. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues? It's better to replace it with a brand new one.
4. Battery Coolant Pump - Even if the temperature sensor is working properly, the battery coolant pump can be at fault and may need replacement. If the pump is not responding to the PCM requests, then the malfunctioned pump can cause overheating of the battery which in turn can affect the vehicle performance.
5. Coolant Hoses/Pipes - Damaged hoses and pipes can cause leakages and thus reduce the effectiveness of the cooling system. Thus, cracked and damaged pipes must be replaced immediately.
6. Cooling System - There can be many components in the cooling system that can be faulty, causing battery overheating and underperforming. So, replace the faulty components immediately.
7. Battery Temperature Sensor - If the temperature sensor is faulty, the ECU will not be able to calculate the battery temperatures and the battery can overheat or run cold. Thus, it is important that the temperature sensors work properly so that the ECU can control the blower fan to manage the temperatures. Buy new battery temperature sensors form us.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of obd2 car scanner, engine coolant temperature sensor, obd2 code reader, transfer case control module and many more. Now all your problems would vanish within no time.

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

After verifying the P0C43 code with an OBD-II scanner, the mechanic should begin with a visual inspection of all hybrid battery pack coolant temperature sensor. Any issues should be repaired, and the code should be cleared from the system. If the code reappears after a retest, the mechanic should then move on to performing voltage tests and resistance tests on the sensor, and comparing the information to the manufacturer’s specifications. If the readings are within the correct limits, then the sensor needs to be replaced. However, if the readings are not within the correct limits, then the issue lies elsewhere. The mechanic should continue checking each possible cause, clearing the code and retesting the system after each attempt, to be sure that the correct solution is found.

Common Mistakes When Diagnosing The P0C43 Code

• Non-performance of the high voltage battery pack coolant temperature sensor
• Failure in the battery energy control module
• Issues related to the wiring
