P08C9 Pressure Control Solenoid M Control Circuit Range/Performance
The current through pressure control solenoid M does not match the commanded value within tolerance. Coil resistance drift or high-resistance contact.
Is it safe to drive with P08C9?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- PossibleCoil resistance changed by thermal stress
- PossibleHigh-resistance contact in solenoid connector
- Less likelySensor element aged beyond calibration window
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
