P2829
Pressure Control Solenoid K Performance/Stuck Off
Transmission
Generic OBD-II
Medium
What it means
P2829 means pressure control solenoid K isn't regulating pressure as commanded and appears stuck off. Because that circuit's hydraulic pressure is lost, the transmission may shift harshly, slip, or fall back to limp mode. Common causes are low or dirty fluid, valve-body debris, or a failed solenoid rather than a no-start condition — start with fluid and the solenoid circuit.
Medium
Can I keep driving? Often driveable but degraded — with the solenoid stuck off, expect harsh shifts, slipping, or limp mode; prolonged slipping wears the transmission, so address it soon.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh, delayed, or flaring shifts (shift shock)
- Transmission slipping or not applying a clutch
- Transmission enters limp/failsafe mode
Common causes
Most likely first
- Pressure control solenoid K stuck off or mechanically hung upLikely
- Low or degraded transmission fluid affecting hydraulic pressureCommon
- Debris or wear in the valve body holding the valve openCommon
- Open, shorted, or corroded solenoid wiring/connectorLess often
- Faulty transmission control module (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check transmission fluid level and condition first — low or contaminated fluid can cause a solenoid to hang.
- Inspect the solenoid K connector and wiring, and measure its resistance against spec.
- If electrical checks pass, the solenoid or valve body is likely stuck — inspect for debris and free or replace the solenoid.
- Clear the code and road-test to confirm the solenoid now responds.
FAQ
Quick answers
Is it safe to drive with P2829?+
Short distances usually, but a stuck-off solenoid can cause slipping that damages clutches over time. Have it diagnosed soon.
Can I just clear P2829?+
'Stuck off' is a performance fault — clearing it won't free the solenoid, so it returns. Fix the fluid, wiring, or solenoid first.
