Motor Electronics Coolant Temperature Sensor A Circuit

Where it lives

For P0A00, the sensor sits on the circuit this code reports. The description of P0A00 reports a fault at the sensor.

Check these first

• A failed motor electronics coolant temperature sensor A
• Open or short in the sensor A wiring
• Corrosion in the sensor A connector
• Low coolant level or degraded coolant
• Sensor A resistance drift out of range

What to do next

1. Check coolant level and condition
2. Inspect the motor electronics coolant temperature sensor A connector
3. Test sensor A resistance against the temperature chart
4. Read sensor A live data
5. Replace motor electronics coolant temperature sensor A if out of range
6. Clear the code and retest
