Drive Motor A Current Sensor Circuit High

Where it lives

For P0A54, the circuit described runs through the sensor. The description of P0A54 reports a fault at the sensor.

Check these first

• A short to voltage in the sensor circuit
• A drive motor A current sensor reading high
• High resistance in the sensor return
• A drive motor A that draws excess current

What to do next

1. Read drive motor A current sensor voltage on a scan tool
2. Test the sensor signal circuit for a short to voltage
3. Measure resistance in the sensor return
4. Check drive motor A for a current draw fault
5. Replace the sensor if the signal reads high
6. Clear the code and retest
