Pressure Control Solenoid A Control Circuit Range/Performance
Powertrain system Generic code P09xx codes Check engine light
What P0961 means
Performance fault of pressure control solenoid A: the circuit is electrically intact, but the solenoid does not behave as commanded. On GM's six-speeds, where A is the line pressure solenoid, the Saab 9-4X 6T70 sets it when measured and commanded current differ for 5 s, GM's 2018 table after 4.4 of 5 s; both Type B, two trips. Allison 1000 flags a current error of 0.5 A or more in 40 of 80 samples (Type A). Ford's 2023 diesel summary lists it as a PC A current range fault. In GM's CVT, A feeds the secondary pulley: a pressure error above 500 kPa steady or 1,500 kPa transient, confirmed by a ratio error, sets it after 5 s. Electrical faults are P0960, P0962 and P0963. The module usually commands maximum line pressure and freezes adaptations.

- Repair difficultyHard
- Typical labor1 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P0961
- Harsh or erratic shifts
- MIL or transmission warning after the second drive
- Slipping or ratio flare on CVT applications
Common causes of P0961
- Most likelySolenoid with internal electrical or mechanical fault, current no longer follows the command
- PossibleDebris or varnish in the fluid sticking the solenoid or regulator valve
- PossibleHigh resistance at connector or pass-through distorting the current
- Less likelyLow fluid level causing pressure errors (CVT pulley monitor)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0961 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 61 | The exact fault in that area. |
What to do next
- Note P0961 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0961
What does P0961 mean?
P0961 means "Pressure Control Solenoid A Control Circuit Range/Performance". Performance fault of pressure control solenoid A: the circuit is electrically intact, but the solenoid does not behave as commanded. It is a generic code, so it means the same on every make.
Is it safe to drive with P0961?
Drive gently and only to a workshop. With P0961 the car can go into limp mode (reduced power) to protect itself.
Will P0961 fail an emissions test?
Yes, it can. P0961 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0961 to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P0961 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
