P0795
Pressure Control Solenoid C
Transmission / hydraulic control
Generic OBD-II
Medium
What it means
P0795 means the transmission control module detected a fault with pressure control solenoid C, which regulates hydraulic line pressure used to apply clutches and time shifts. When that pressure is wrong, the transmission can slip, shift harshly, or drop into limp mode. It's usually the solenoid or its wiring, but low fluid and the valve body are worth ruling out.
Medium
Can I keep driving? Drivable but expect harsh shifts or slipping — fix it soon, since sustained slipping from low apply pressure can damage internal clutches.
Common symptoms
What you'll notice
- Harsh or delayed shifting
- Transmission slipping
- Erratic or inconsistent shifting
- Limp mode (fixed gear)
- Check-engine light on
Common causes
Most likely first
- Failed pressure control solenoid CLikely
- Wiring or connector fault in the solenoid C circuitCommon
- Low or dirty transmission fluidCommon
- Stuck or worn valve bodyLess often
- Failed transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Check transmission fluid level and condition first.
- Scan for companion pressure or shift codes.
- Inspect the solenoid C connector and wiring for damage or corrosion.
- Electrically test pressure control solenoid C and compare to spec.
- Replace the solenoid or valve body as needed; evaluate the TCM last. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0795?+
For short trips, but wrong line pressure can make the transmission slip or shift harshly. Because slipping generates heat and wear, have it repaired soon.
Can I just clear P0795?+
You can, but it returns until the solenoid or its circuit is fixed — the TCM monitors line pressure continuously.
