P0BCE - OBD Trouble Code

<<See All OBD Codes

What does the P0BCE error code signify? How does this error gets stored in the vehicle? If you are looking for a solution, then proceed further. Updating the software of the transmission control module is generally known as the generator inverter temperature sensor circuit low. If a failure is found within the generator motor high voltage inverter, then the P0BCE error code gets stored in the vehicle.

The MG ECU which is placed in the inverter with converter assembly will look out for the temperature of the generator inverter with the help of temperature sensor that is inbuilt in the generator inverter. The inverter output will be limited by the MG ECU if there is a need so that, overheating of the generator inverter can be avoided. The power management control ECU (HV CPU) will also find out if there is any malfunctioning in the sensor depending on the values of the temperature sensor. Any faults will be identified by the inverter with converter assembly in the generator inverter temperature sensor as well as its electrical wires.

What causes this problem with the Generator Inverter Temperature Sensor Circuit Low?

• Damaged inverter with converter assembly.
• There might be an opening or the inverter with converter assembly harness might have a short circuit.
• The electrical connection of the inverter with converter assembly circuit might be weak.

1. Inverter Cooling System - Carefully check the inverter cooling system for any possible damages. If they are defective, replace them quickly.
2. Auto Cooling Fan - The auto cooling fan motor works along with the radiator to pull air. If the cooling fan fails then the vehicle will start malfunctioning. Get rid of the faulty cooling fan as soon as possible.
3. Inverter With Converter Assembly - P0BCE error can be avoided if the faulty inverter with converter assembly is replaced with a new one.
4. Inverter Water Pump Assembly - The P0BCE error code can be avoided if the defective inverter water pump assembly is instantly changed by getting a new one from Parts Avatar.
5. Inverter Temperature Sensor - P0BCE error code can get stored in your vehicle if the inverter temperature sensor is broken or damaged. Find the replacement for inverter temperature sensor from Parts Avatar at best prices online.
6. Engine Control Module - Does your car jump start on reverse polarity? It is an indication of damaged ECM. Repair / replace it soon to avoid P0BCE error.
7. Powertrain Control Module - If you find the check engine light on the display dashboard, then the PCM is faulty. Replace it as soon as possible to avoid the P0BCE error.

Common Symptoms

• You might find the engine light or else the warning light of the service engine turned on

We have listed out so ways which would help you to correct the occurrence of OBD Code P0BCE. They are mentioned here as follows:

• Fixing the defective inverter temperature sensor.
• Replacing the damaged cooling fan.
• Faulty inverter with converter assembly and inverter water pump assembly has to be changed.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of inverter with converter assembly, transmission control module, inverter temperature sensor and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• This is a general type of error code, where the mechanic will use a scanner to check for the stored error codes.
• To the diagnostic port, the mechanic will attach the scanner so that every of the stored codes and freeze frame data is retrieved.
• As a first step, the mechanic will start inspecting the inverter cooling system and inverter temperature sensor as they can give rise to issues in the vehicle.
• After this, the mechanic will start inspecting the components of inverter with converter assembly, transmission control module, inverter water pump assembly, cooling fan and so on for some possible damages or defects.
• If they are defective the mechanic will replace them as needed.
• As a very rare case, the mechanic may come across the faulty engine control module which has to be replaced.
• After every diagnostic process is carefully done, make sure that you reset the code and test drive the vehicle. This has to be done to see if the error codes still appear.
• This step will eventually help the mechanic or the technician to know if the code is still stored and help him to locate the area as to where the fault occurred.

Common Mistakes When Diagnosis the P0BCE Code

• Electrical wires might cause some issues.
• Failure of the inverter.
• Updating the transmission control module software.
• Faulty inverter temperature sensor.
