P0C47 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0C47 can be elucidated as Hybrid Battery Pack Coolant Pump Control Circuit/Open. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

Want to learn something more about the P0C47 fault code? It is the engine control module which would examine the hybrid battery pack coolant pump control circuit. This trouble code would be set by the ECM when the hybrid battery pack coolant pump control circuit would not be as per the parameters set by the manufacturer.

What causes this problem with the Hybrid Battery Pack Coolant Pump Control Circuit/Open?

• Imperfect hybrid battery pack coolant temperature sensor
• Issue of unbolted hybrid battery pack coolant temperature sensor harness
• Unacceptable electrical connection in the hybrid battery pack coolant temperature sensor circuit

1. Engine Control Module - ECM faults are rare but can be a big problem as faulty ECM will cause wrong vehicle operations and can also result in wrong OBD codes getting stored in the system which can also cause misdiagnosis. Thus, replace faulty ECM components now!
2. 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.
3. Car Battery - The car battery can also be at fault and might have the problem of overcharging and fast discharging. This can cause increased temperatures and can also affect the functioning of various sensors like the speed sensor, temperature sensor and many more. Thus, replace faulty car battery today!
4. Battery Coolant Pump - The battery coolant pump maintains the battery temperatures and optimises the air flow to keep the battery running properly. It the coolant pump gets damaged, then all the components associated with the battery can get damaged and the vehicle may enter fail safe mode to avoid damages. Thus, timely replace faulty coolant pump.
5. Powertrain Control Module - Check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
6. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P0C47 error with the help of experienced mechanic. Visit us today!

Now all your problems would vanish within no time.

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

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the hybrid battery pack coolant temperature sensor itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the hybrid battery pack coolant temperature sensor is not faulty, he will then retune the code and test drive the vehicle.
• On test driving, if the P0C47 code does not return soon, he will know that an erratic condition exits.
• But if the error returns instantaneously, he will check every components of the control module as well as the circuit like connectors, wires, harness, fuses etc for any possible fault
• If any component is damaged, he will fix them right away.
• After performing this repair, he will inspect the transmission fluid as well as its level.
• If the level is below the manufacturer’s specification, it has to be refilled and if the fluid is murky or contaminated it needs to be replaced.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.
• A sure sign of this is smoke or steam being emitted from underneath the hood. The ignition timing could be set incorrectly and will require adjustment.

Common Mistakes When Diagnosing The P0C47 Code

• High voltage powertrain control module related issues
• Quirks in the high voltage cooling system
• There might be less coolant in the high voltage system
• Defaults in the water pump
