P0962
Pressure Control Solenoid A Control Circuit Low
Transmission controls
Generic OBD-II
Medium
What it means
P0962 means the transmission control module detected an abnormally low voltage in the control circuit for pressure control solenoid 'A', the solenoid that regulates transmission line pressure. It usually points to a wiring short or open, or a failed solenoid, and often shows up as harsh shifts or a limp-mode condition rather than a no-start.
Medium
Can I keep driving? Usually driveable, but the transmission may drop into limp mode with harsh or limited shifting — fix it soon to avoid added wear.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh, delayed, or erratic gear shifts
- Transmission stuck in a limited-gear limp mode
- Reduced fuel economy
Common causes
Most likely first
- Short-to-ground or open in the pressure control solenoid 'A' wiringLikely
- Failed pressure control (line-pressure) solenoid 'A'Common
- Loose or corroded connector at the solenoid or transmission harnessCommon
- Faulty transmission control module (TCM) — less commonLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the solenoid 'A' connector and wiring for shorts, opens, or corrosion.
- Measure the solenoid circuit for the correct resistance and check for a short to ground.
- Test the pressure control solenoid's resistance against spec and replace it if out of range.
- If wiring and solenoid are good, have the TCM diagnosed. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0962?+
Short trips are usually fine, but the transmission may shift harshly or enter limp mode. Prolonged driving with wrong line pressure can wear the transmission, so repair it promptly.
Can I just clear P0962?+
It will return once the circuit fault is present again. The low-voltage condition needs to be traced and repaired.
