Drive Motor A Current Sensor Circuit Range/Performance

Where it lives

For P0A52, the description names the sensor as the part involved.

Check these first

• A drive motor A current sensor that drifts under load
• Chafed wiring in the sensor harness
• A sensor connector with a backed out pin
• Excessive current draw from drive motor A

What to do next

1. Compare drive motor A current sensor data to a known good value
2. Wiggle test the sensor harness and connector
3. Measure the sensor output across its operating range
4. Check drive motor A for excessive current draw
5. Replace the sensor if the reading drifts
6. Clear the code and retest
