Guide To P0BCD OBD Error Code Solutions

<<See All OBD Codes

What are the symptoms for P0BCD error code? Is the inverter cooling system malfunctioning? Then there is a high chance that the P0BCD error code is stored in your vehicle. Improper functioning of the inverter is known as generator inverter temperature sensor circuit. If an issue is found in the generator motor high voltage inverter then the P0BCD error will get stored in the vehicle.

The temperature of the generator inverter will be found by the MG ECU which is placed in the inverter with converter assembly with the help of temperature sensor that is built in the generator inverter, if there is a need, the MG ECU will start limiting the inverter output so as to avoid the overheating of the generator inverter. Any malfunction in the sensor will also be found by the power management control ECU (HV CPU) depending on the readings of the temperature sensor. Any issue in the generator inverter temperature sensor as well as its wiring will be found out by the inverter with converter assembly.

What causes this problem with the Generator Inverter Temperature Sensor Circuit Range/performance?

• The inverter with converter assembly might be defective.
• There might be an opening in the inverter with converter assembly or the circuit might be shorted.
• The electrical connection of the inverter with converter assembly circuit might appear to be weak.
• Inverter cooling system might be broken.
• Malfunctioning of the cooling fan system.
• Inverter water pump assembly might have been damaged.

1. Inverter Cooling System - Do you find the inverter cooling system to be defective? Find the replacement for inverter cooling system at the best prices from Parts Avatar.
2. Auto Cooling Fan - If the auto cooling fan starts overheating, then the vehicle will start malfunctioning. Get rid of it as soon as possible by getting a new cooling fan from Parts Avatar.
3. Inverter With Converter Assembly - Visually inspect the inverter with converter assembly. If it is damaged, replace it as soon as possible to avoid the P0BCD error code.
4. Inverter Water Pump Assembly - The contaminated inverter water pump assembly has to be quickly replaced to avoid the P0BCD error.
5. Inverter Temperature Sensor - Find the replacement for the damaged inverter temperature sensor from Parts Avatar at best prices online to avoid the P0BCD error from getting stored.
6. Engine Control Module - Conditions of misfire indicates that the ECM is faulty which needs replacement as soon as possible.
7. Powertrain Control Module - Does your engine turn off without any reason? Then it’s a high time to replace your PCM as it can be faulty

It is essential 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 P0BCD here:

Common Symptoms

• You will notice either of the lights, that is the engine light or the warning light of the service engine turned on.

Here are some ways with the help of which you will be able to correct the OBD Code P0BCC.

• The damaged inverter temperature sensor will need immediate fixation.
• Replacing the faulty inverter with converter assembly and inverter water pump assembly.
• Defective cooling fan must be altered.

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

• This is a general type of error code, where the diagnosis process and the repair work is not difficult to execute.
• Whenever this error arises, the mechanic will use a scanner to check the trouble codes in the vehicle. But a trained professional will use an advanced scanner like Autohex- to check for advanced diagnostic process.
• The mechanic will carefully look into the inverter cooling system and inverter temperature sensor.
• If they are broken, damaged or corroded. If they are defective it will be replaced quickly.
• After this, the mechanic will look for possible damages in some of the electrical components like cooling fan system, inverter with converter assembly, inverter water pump assembly and so on.
• Any damage to these components can also result in the storing of the error code.
• As a very rare case, you will find the engine control module or the powertrain control module to be faulty which has to be replaced quickly.
• If there are any other error codes, they must be rectified first, before further proceeding with the P0BCD error code.
• After the diagnosis, it is good to always reset the code and the vehicle must be test driven to know if the issue is resolved.
• Test driving the vehicle will help the mechanic to know as to where the error occurred

Common Mistakes When Diagnosis the P0BCD Code

• Inverter might be broken.
• Problematic wires.
• Inverter temperature sensor might be malfunctioning
