Error Code P0C36: What It Means & What To Do?

<<See All OBD Codes

The hybrid battery temperature sensor is present along the battery and measures the battery temperature within the battery system to maintain the optimal temperatures. If the powertrain control module detects that the hybrid battery temperature sensor is not functioning properly, it stores OBD code P0C36 in the system, flashing Malfunction indicator light on the dashboard.

The temperature sensor works closely with the Powertrain Control Module so as to manage its functioning of the coolant system. The pump starts to work when the battery circuit is high and modulates the speed as per the circuit inputs. If the PCM detects any performance abnormalities in the hybrid battery temperature sensor “F” circuit, it sets OBD code P0C36 in the system.

What causes this problem with the Hybrid Battery Temperature Sensor "F" Circuit High?

• Flaws in the hybrid battery pack
• Faulty hybrid battery temperature sensor
• Faulty sensor thermistor
• Hybrid battery pack harness might be opened or shorted
• Hybrid battery pack circuit might have bad electrical connection

1. Engine Control Module - ECM program faults can lead to misinterpretation of data causing wrong OBD codes to get stored in the system, leading to vehicle showing erratic behaviour. Thus, it is important to repair, replace and reprogram the ECM and its components.
2. 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.
3. 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.
4. Cooling System - There can be many components in the cooling system that can be faulty, causing battery overheating and under performing. So, replace the faulty components immediately.
5. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.
6. 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 from us.

Interested in knowing the symptoms to OBD code P0C36? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with Hybrid Battery Temperature Sensor "F" Circuit High.

Common Symptoms

• Engine not starting

Here are some steps which you should follow in order to diagnose this P0C36 fault code:

• As an initial step the mechanic will carefully inspect the vehicle with the help of a scanner.
• After this, the technician will connect a scanner to the diagnostic code so that he can recover all the codes and freeze frame data.
• Note down this information as it can clearly help for further diagnosis.
• After careful inspection, he will reset the code and test drive your vehicle to check for reappearance of the codes.
• He will know that an intermittent condition persist, if the code does not return instantly.
• But if the error code returns quickly, the vehicle is test driven, and then he has to inspect the transmission fluid.
• If any of the component is damaged, the mechanic will replace them quickly.
• Most often, whenever the mechanic carries out any repair work, he will reset the code and test drive your car, to check if the codes return immediately. This can preferably help the mechanic to know what caused this error code in the vehicle.

 Common Mistakes When Diagnosing The P0C36 Code

• Some issues related to the battery contactor assembly
• PCM and ECU faults
• Faults in the wiring and harness
• Failure in the battery energy control module
