| Meaning | P0A6E: Drive Motor “B” Phase W Current High |
| Is it serious? | Yes, this issue can cause improper functioning of drive motor “B,” which may affect vehicle performance, especially in hybrid or electric vehicles. |
| Possible causes | – High phase W current in drive motor B – Faulty phase W current sensor – Signal processing issue |
| How to diagnose? | – Measure phase W current in drive motor B – Test phase W current sensor operation – Inspect signal processing module |
P0A6E Meaning
The P0A6E: Drive Motor “B” Phase W Current High code indicates that the current sensor for phase W in drive motor “B” is detecting a higher-than-expected current. This may lead to improper motor operation and affect the performance of the vehicle’s electric drive system. The issue could be due to a malfunctioning current sensor, wiring problems, or a fault in the signal processing module.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related fault codes that might provide additional insights. | OBD-II Scanner |
| Measure Phase W Current | Use a multimeter to measure the phase W current in drive motor “B” and compare it to manufacturer specifications to confirm if the current is too high. | Multimeter |
| Test Phase W Current Sensor | Use a diagnostic tool to test the phase W current sensor’s functionality and ensure it is operating correctly. | Diagnostic Tool, Multimeter |
| Inspect Signal Processing Module | Test the signal processing module to verify it is correctly interpreting the sensor data and not causing the high current readings. | Diagnostic Tool |
| Inspect Wiring for Damage | Visually inspect the wiring between the phase W current sensor and the signal processing module for signs of damage, disconnections, or corrosion. Repair or replace as necessary. | Flashlight, Multimeter |
| Clear the Code and Test Drive | After completing repairs, clear the fault code using an OBD-II scanner and take the vehicle for a test drive to confirm the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0A6E code does not return. | OBD-II Scanner |
