Drive Motor B Temperature Sensor Circuit Intermittent

Where it lives

For P0A34, the circuit described runs through the sensor. The description of P0A34 reports a fault at the sensor.

Check these first

• A drive motor B temperature sensor connector losing contact
• Chafed wiring in the sensor harness
• A sensor that fails when hot
• Electrical interference on the sensor circuit

What to do next

1. Road test and watch drive motor B temperature sensor data
2. Wiggle test the sensor connector and harness
3. Measure the sensor signal hot
4. Check for electrical interference nearby
5. Replace the sensor if the signal drops
6. Clear the code and retest
