Guide To P0C32 OBD Error Code Solutions
OBD Code P0C32 - Hybrid Battery Cooling System Performance
If the battery cooling system is at fault, the battery can overheat and
result in various performance issues. The most common symptoms include Check
Engine Light illumination, vehicle not starting due to overheating and faster
discharge from the battery. Thus, whenever the hybrid battery cooling system
doesn’t perform to its expectations, OBD code P0C32 gets stored in the
powertrain control module (PCM).

The hybrid battery contains 3 temperature sensors that continuously
measure the batter temperature using its thermistors. The resistance of the
thermistor tells the PCM about the battery temperatures. If the battery
temperature is less, the thermistor will have high resistance and if the
temperature is high, the resistance will get lowered. This resistance is
measured by the ECU which then determines the optimal flow of the blower fan to
keep the battery functioning properly. If the cooling system is not working
properly, the OBD code P0C32 will set in the system and the vehicle can go into
fail safe mode.
What causes this
problem with the Hybrid Battery Cooling System Performance?
- Hybrid battery thermistor faulty
- Battery smart unit failure
- Faulty battery temperature sensor
- Damaged wiring and connectors in relation to the sensor and circuit
Replace/Repair These Parts To Fix Code P0C32
- 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.
- 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!
- 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.
- Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
- Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
- Diagnostic Tools - Take help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment from us!

Easy Diagnosis Of Engine Error OBD Code P0C32
If you want to easily diagnose this P0C32 fault code, then all you have
to do is to follow the steps which are mentioned below:
- 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
retune the code and test drive the vehicle.
- On test driving, if the P0C32 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,
and fuses 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 P0C32 Code
- Battery contactor assembly issues
- Hybrid Battery circuit issue
- Faulty battery harness and connectors
- Energy Control Module faults
