What this code means
The TCC solenoid did not move when the PCM commanded it. This is an information code — there should be a more specific code stored in the Transmission Control Module. The TCC solenoid circuit performance is not as expected.
Symptoms
- Check Engine Light
- TCC not engaging
- Reduced fuel economy on highway
- Transmission overheating at highway speeds
Common causes
- Faulty TCC solenoid
- Wiring issue to TCC solenoid
- Low transmission fluid
- Internal transmission blockage
- Contaminated transmission fluid
Diagnostic steps
- Check for additional transmission DTCs in TCM
- Test TCC solenoid resistance
- Inspect TCC solenoid wiring
- Check transmission fluid level and condition
Repair notes
Check for companion DTCs. Replace TCC solenoid if faulty. Service transmission fluid.
