P0961Pressure Control Solenoid A Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Harsh or erratic shifts
- MIL or transmission warning after the second drive
- Slipping or ratio flare on CVT applications
- Likely causes
- 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
- RareLow fluid level causing pressure errors (CVT pulley monitor)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €200 – €2,500
