Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not condemn the controller before checking pressure solenoid C wiring and connector integrity.
Useful checks before replacing parts
- Check for short-to-voltage, open ground, poor connector contact, and pressure solenoid C control circuit faults.
- Compare solenoid command with circuit voltage or current and pressure behavior during shifts.
- Inspect transmission connector sealing, internal harness routing, and recent wiring repairs.
