P0C41 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0C41 can be described as DC/DC Converter Temperature Sensor "B" Intermittent/Erratic. The temperature of the boost converter is detected by the MG ECU by utilizing the sensor built into the boost converter. The temperature sensor outputs voltage is used by the boost converter which would change between 0.5 and 4.5 V in response to a change in temperature. With the increase in the boost converter temperature, there would be a decrease in the output voltage. Similarly, decrease in the boost converter temperature, there would be an increase in the output voltage. The MG ECU limit load depends upon signals which are sent from the boost converter temperature sensor to help prevent excessive heating. All the malfunctions in the boost converter temperature sensor as well as wiring would be detected by the MG ECU.

Don’t worry if P0C41 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. 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 make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

What causes this problem with the DC/DC Converter Temperature Sensor "B" Intermittent/Erratic?

• There can be inoperative inverter with converter assembly

1. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have best auto parts for our customers.
2. Inverter Cooler Pump - As part of the cooling system, the inverter coolant pump translates high-voltage direct current generated by hybrid batteries into alternating current for the motor to keep the system at the proper operating temperature. Thus, if the cooler pump if faulty, it should be replacing immediately.
3. Battery Temperature Sensor - A symptom commonly associated with a failing battery temperature sensor is an engine that surges during operation. The battery temperature sensor helps the system continuously adjust the system voltage, and if it fails, this process may be disturbed. Thus, replace it now!
4. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
5. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So, it is very important to replace the defective electronic control unit with us at equitable prices.
6. Diagnostic Tool - Use high grade diagnostic tools and equipment to resolve OBD code error. Buy new tools and equipment form us now!

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

• Use an OBD-II scanner in order to verify that the code is present, and check for other codes for any other type of error or problem that might need attention.
• The current data along with freeze frame data are recorded, and the codes are then cleared to see if they reoccur.
• The vehicle is inspected for any problems with the wiring and connectors to check for loose connections, corrosion, or shorts.
• The tests related to the DC converter temperature sensor and components may help pinpoint the problem, as well as inspection of the current sensor and cut off switch will further be helping the cause.
• The P0C41 error is triggered if there is a physical problem with the DC converter temperature sensor which could cause the engine performance to go off.

Common Mistakes When Diagnosing The P0C41 Code

• Inverter/converter assembly might start failing
