Shift Solenoid G Control Circuit High

Where it lives

For P099C, the solenoid sits on the circuit this code reports. The description of P099C reports a fault at the solenoid.

Check these first

• Short to voltage in the shift solenoid G control circuit
• An open in the shift solenoid G circuit
• High resistance in the shift solenoid G circuit
• A failed shift solenoid G
• A fault in the TCM or PCM

What to do next

1. Check transmission fluid level and condition
2. Inspect shift solenoid G wiring and connector
3. Test the solenoid G circuit resistance
4. Command shift solenoid G with a scan tool
