P0C6F - OBD Trouble Code

<<See All OBD Codes

It is important to know that the wrong battery temperatures will affect the engine performance in terms of acceleration and ride quality. Also affected by the sluggish throttle response and the braking risk, the OBD code P0C6F error code gets stored in the PCM indicating problematic hybrid battery temperature sensor “B/C” correlation issue.

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 Temperature Sensor "B"/"C" Correlation?

• Problematic hybrid battery thermistor
• Battery smart unit failure
• Faulty, open or shorted battery connectors and wiring harness
• Damaged electrical connection to the battery temperature sensor and thermistor
• Powertrain Control Module faults

1. Battery Current Sensor - Most of the time the battery current sensor is faulty and is unable to detect the battery operations properly and thus the reading doesn’t correlate with the temperature sensor readings, causing OBD code P0C6F to get stored in the PCM
2. Battery Coolant Pump - It is important to understand the functioning and diagnosis of faulty coolant pump as it is the most important component for keep the battery temperatures under control and keeping it functional all the time. Thus, replace fault battery coolant pump now!
3. Powertrain Control Module - Faulty PCM should be repaired, replaced and reprogrammed as it can cause a lot of problems in the vehicle by affecting the engine performance along with the transmission, fuel delivery and exhaust systems.
4. Hybrid Battery - The battery itself can be faulty and can be overheating, which can lead to faster discharge and slower charging, with risks of leakages and other damages to the vehicle. Thus, immediate replacement is advisable.
5. Car Battery & Cables - Most of the time it is the cables and connector that are at fault and are a cheap and easy way diagnose this error. Thus, replace faulty wiring and connectors immediately.
6. Diagnostic Tool - Make use of quality diagnostic tools to resolve any OBD error code. Buy quality diagnostic tools from us!
7. Battery Temperature Sensor - Temperature sensor measure the battery temperature so that it can be monitored for overheating and other problems in association with the battery. Thus, it is important for the temperature sensor to keep working properly and must be replace, if found faulty. 

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0C6F here:

Common Symptoms

• Malfunction Indicator Light On
• Sluggish acceleration
• Lights and electrical components not working properly
• PCM and ECU faults

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0C6F code to be stored:

• 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 solenoid 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 solenoid or the control modules are not faulty, he will then re-tune the code and test drive the vehicle.
• On test driving, if the P0C6F 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.

Common Mistakes When Diagnosing the P0C6F Code

• PCM and ECU failure
• Wiring and connectors damaged, broken or short
• Hybrid battery temperature sensor failure
