The P0BD2: Drive Motor Inverter Temperature Sensor “C” Circuit Range/Performance fault code refers to a performance issue with the drive motor inverter temperature sensor labeled “C”. This problem may arise from a faulty sensor, wiring or circuit issues, or a malfunctioning control module, affecting the sensor’s ability to provide accurate temperature readings for the inverter.
P0BD2 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0BD2: Drive Motor Inverter Temperature Sensor “C” Circuit Range/Performance |
| Is it serious? | Yes, incorrect temperature readings can lead to overheating of the drive motor inverter, potentially causing damage to the hybrid system. |
| Possible causes | – Sensor “C” performance issue – Faulty sensor or control module – Wiring or circuit problems |
| How to diagnose? | – Verify the range and performance of sensor “C” – Test sensor and control module – Inspect wiring and connections |
P0BD2 Meaning
The P0BD2 code indicates that the drive motor inverter temperature sensor “C” is not performing within its expected range. This could lead to improper temperature monitoring of the inverter, resulting in inefficient cooling and potential overheating of the drive motor inverter.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related codes that could provide further insights into the inverter system or sensor performance issues. | OBD-II Scanner |
| Verify the Range and Performance of Sensor “C” | Use a multimeter to measure the resistance and output of temperature sensor “C”. Compare the readings to manufacturer specifications to ensure that the sensor is functioning within the proper range. | Multimeter, Diagnostic Tool |
| Test the Control Module | Check if the control module is correctly processing the data from temperature sensor “C”. Reprogram or replace the control module if it is malfunctioning. | Diagnostic Tool |
| Inspect Wiring and Connections | Visually inspect the wiring and connections related to sensor “C” for signs of damage, corrosion, or loose connections that could affect performance. | Flashlight, Multimeter |
| Check for Circuit Issues | Investigate any circuit issues, such as short circuits, open circuits, or blown fuses that could be disrupting sensor performance. | Multimeter, Circuit Tester |
| Replace Faulty Sensor | If sensor “C” is found to be faulty or not functioning within the specified range, replace it to restore proper temperature monitoring. | Replacement Sensor |
| Clear Codes and Test Drive | After repairs, clear the fault codes using an OBD-II scanner and take the vehicle for a test drive to verify that the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to confirm that the P0BD2 code does not return. | OBD-II Scanner |
