P2814
Pressure Control Solenoid G Control Circuit Low
Transmission
Generic OBD-II
Medium
What it means
P2814 means the transmission control module detected a low-voltage condition (short-to-ground or open) in the control circuit for pressure control solenoid G. That solenoid regulates hydraulic pressure for a clutch or shift element, so the fault typically shows up as harsh or erratic shifting and can put the transmission into limp mode. It's most often a wiring or solenoid problem.
Medium
Can I keep driving? Drivable with care — expect harsh or delayed shifts and possible limp mode; have the transmission solenoid circuit checked soon.
Common symptoms
What you'll notice
- Harsh, delayed, or erratic shifts
- Transmission slipping or not engaging a specific gear
- Limp mode (stuck in a single gear)
- Check-engine light on
Common causes
Most likely first
- Short-to-ground or open in the pressure control solenoid G control circuitLikely
- Failed pressure control solenoid GCommon
- Damaged wiring or corroded connector at the solenoidCommon
- Low or dirty transmission fluid affecting solenoid operationLess often
- Valve-body or transmission control module faultLess often
How to diagnose & fix
Work through it in order
- Scan and read freeze-frame data to confirm the circuit and fault type.
- Check transmission fluid level and condition first.
- Inspect the solenoid G wiring and connector for shorts to ground or open circuits.
- Measure the solenoid's resistance against spec.
- Replace the solenoid or valve body as needed, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2814?+
Short trips at moderate speed are usually possible, but harsh shifting or limp mode makes it unreliable. Have it diagnosed before extended driving to avoid further transmission wear.
Can I just clear P2814?+
It will return once the solenoid circuit is read again. The wiring, solenoid, or fluid issue must be fixed for the code to stay off.
