P0BD0 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0BD0 can be elucidated as Generator Inverter Temperature Sensor Circuit Intermittent/Erratic. It is the MG ECU which is situated in the inverter with converter assembly which would detect the temperature of the generator inverter by utilizing the temperature sensor built into the generator inverter. If it is required, then the MG ECU would limit inverter output to help prevent generator inverter from overheating. The power management control ECU (HV CPU) would also detect malfunctions in the sensor depending upon the temperature sensor values. It is the inverter with converter assembly which would detect malfunctions in the generator inverter temperature sensor and its wiring.

The error code P0BD0 would be stored when a failure would be detected within the generator motor high voltage inverter. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle to another.

What causes this problem with the Generator Inverter Temperature Sensor Circuit Intermittent/Erratic?

• Some issues related to the inverter cooling system
• Flaws in the cooling fan system
• Defects in the inverter with converter assembly
• Faulty inverter water pump assembly

1. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times, a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
2. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration. Buy high grade PCM online from us.
3. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues? It's better to replace it with a brand new one.
4. Hybrid Battery - Whenever the hybrid battery fails, one is likely to experience a fall in the MPG. Apart from this, a failure in the hybrid battery is likely to trigger symptoms that may lead to an unusual MPG. in addition to these the driver is likely to observe a high mileage. So, in order to prevent expensive repairs, we recommend you to change the hybrid battery right away from Parts Avatar.
5. 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.
6. 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.
7. Cooling System - There can be many components in the cooling system that can be faulty, causing battery overheating and underperforming. So, replace the faulty components immediately.
8. 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 form us.

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

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Check for the damaged generator inverter temperature sensor circuit and its components for error. It the mechanic finds the fault in the connectors in relation to the generator inverter temperature sensor circuit, replace it immediately.
• Also check for the particular battery cells emitting high voltages and thus might need battery replacement as well.
• Parts or components should not be replaced with reference to only a P0BD0 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
• If all the components seem to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing The P0BD0 Code

• Inverter might start failing
• Issues with the inverter temperature sensor
