Pressure Control Solenoid C Control Circuit High

Where it lives

For P0971, the solenoid sits on the circuit this code reports. The description of P0971 reports a fault at the solenoid.

Check these first

• A short to power in the solenoid C control circuit
• An open in the solenoid C ground circuit
• A pressure control solenoid C that is stuck closed
• A TCM fault driving the circuit high
• Corrosion at the solenoid C connector

What to do next

1. Read solenoid C voltage on a scan tool
2. Check the circuit for a short to power
3. Test the ground circuit for an open
4. Inspect the connector pins
5. Replace solenoid C if it is stuck
6. Clear the code and retest
