Guide To P0C6E OBD Error Code Solutions

<<See All OBD Codes

Are you experiencing sluggish performance and acceleration? Is there a problem with the engine performance and affected fuel economy? All this with lights keeping stayed on due to high voltage may be due to vehicle battery problems leading to OBD code P0C6E error getting stored in the PCM.

OBD-II Code P0C6E is defined as a Hybrid Battery Temperature Sensor "A/B" Correlation Issue. The battery temperature sensor is responsible to keep in check that the hybrid battery is operating under normal temperature conditions. When the sensor notices problem with respect to “A/B” correlation, the PCM will set the OBD code P0C6E error in the system and it may go into limp mode.

What causes this problem with the Hybrid Battery Temperature Sensor "A"/"B" Correlation?

• Hybrid battery temperature sensor faulty
• Open or shorted harness to hybrid battery temperature sensor
• Poor electrical connections to hybrid battery temperature sensor

1. Battery Temperature Sensor - Faulty temperature sensor will not be able to interpret the battery temperatures which can cause overheating and leakages inside the battery that can cause harm to various components and can be dangerous to driver’s safety also. Thus, replace it at first instance.
2. Battery Coolant Pump - Battery coolant pump plays a vital role in keeping the battery pack cool while operating and keeping it from overheating. Thus check and replace faulty pump as it can be the reason for temperature sensor indicating out of bound readings.
3. Powertrain Control Module - P0C6E code can display due to some issues in the Powertrain Control Module. Faulty PCM can lead to engine stalling and vehicle going into fail safe mode. Thus the PCM might need to be repaired, replaced or reprogrammed, if required.
4. Hybrid Battery - If the battery if at fault, it can also be the reason for battery overheating, which can lead to temperature sensor going out of specification. Buy new hybrid battery now!
5. Car Battery & Cables - Most of the time the battery cables and connectors are at fault for a particular component not functioning properly. Thus, the battery cable and connector should be checked for and replace in time.
6. Diagnostic Tool - Usually any OBD code problem requires deep insight into the problem and high grade tools in order to fix it properly. Thus, buy quality diagnostic tools from us!

Well, if you are looking to know about the common symptoms related to this error code P0C6E, we are have worked out a small list to help you discover this error code with your vehicle.

Common Symptoms

• Light may stay on or work intermittently
• Check Engine Light On
• PCM faults
• Vehicle going into limp mode

Here are some ways with the help of which you will be able to correct the OBD Code P0C6E

• It is essential to restore the flawed hybrid battery temperature sensor
• Repair or replace the quirky hybrid battery cut off switch circuit
• Carefully adjust the faults in the hybrid battery thermistor
• The hybrid battery temperature harness should be restored to working order
• Recondition the non-functioning battery assembly
• Repair or replace battery interface control module (BICM)
• Adjust the flawed hybrid battery temperature sensor circuit

Here are some steps which you should follow in order to diagnose this P0C6E fault code:

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Check for the damaged hybrid battery temperature sensor and its components for error. It the mechanic finds the fault in the connectors in relation to the battery, replace it immediately.
• Also check for the particular battery cells emitting high voltages and thus might need battery replacement as well.
• 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. If, when looking under the hood, you notice that the drive belts appear loose, they need to be tightened or completely replaced.
• If there is a noticeable pool of fluid underneath the car, this could be a sign of the cylinder head gasket failing. That will be confirmed in the form of billowing smoke being blown from the exhaust system.
• Parts or components should not be replaced with reference to only a P0C6E DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
• If all the components seems to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing the P0C6E Code

• Wiring and connector issues
• Hybrid battery cells issue
• Hybrid battery temperature sensor faulty
• PCM and ECU issues
