Drive Motor B Inverter Voltage Sensor A” Circuit Low

Where it lives

For P0DA5, the circuit described runs through the sensor. The description of P0DA5 reports a fault at the sensor.

Check these first

• A short to ground on the drive motor B inverter voltage sensor signal
• A failed inverter voltage sensor reading low
• High resistance in the sensor circuit
• A corroded connector pin at the inverter

What to do next

1. Read the inverter voltage sensor on a scan tool
2. Check the sensor signal for a short to ground
3. Inspect the inverter connector for corrosion
4. Compare the reading to a meter at the supply
5. Service the inverter if the reading stays low
6. Clear the code and retest
