P0969
Pressure Control Solenoid C Control Circuit Range/Performance
Transmission control
Generic OBD-II
Medium
What it means
P0969 means the signal from transmission pressure control solenoid C is outside its expected range. This solenoid regulates hydraulic line pressure, so a fault can cause harsh or erratic shifting, slipping, and extra heat. Check the fluid and the solenoid wiring first — low fluid and connector problems are common triggers before the solenoid itself.
Medium
Can I keep driving? Driveable but fix promptly — this solenoid regulates line pressure, so harsh shifting, slipping, or overheating can damage the transmission if ignored.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh, erratic, or delayed shifting
- Reduced acceleration or a slipping feel
- Transmission may run hotter than normal
- Possible failure to fully engage a gear
Common causes
Most likely first
- Faulty pressure control solenoid CLikely
- Wiring or connector fault in the solenoid circuitCommon
- Low or degraded transmission fluidCommon
- Internal hydraulic/mechanical problem in the transmissionLess often
- Faulty transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check transmission fluid level and condition first.
- Inspect the solenoid connector and wiring for damage, corrosion, or loose pins.
- Test pressure control solenoid C resistance and operation; replace if out of spec.
- If the electrical side is good, check line pressure and inspect for internal hydraulic faults.
- Have the TCM tested and replaced only if wiring, solenoid, and hydraulics check out.
FAQ
Quick answers
Is it safe to drive with P0969?+
For short distances yes, but slipping or overheating from bad line-pressure control can damage the transmission, so get it diagnosed soon.
Can I just clear P0969?+
It will come back until the solenoid, wiring, or fluid problem is fixed. Clearing it does not restore proper pressure control.
