What P0965 means
Performance fault of pressure control solenoid B: wiring is intact, but current or resulting pressure does not match the command. In the Saab 9-4X 6T70, solenoid 2 feeds the 3-5-reverse clutch; a current mismatch for 5 s sets a Type C code without MIL and freezes that clutch's adaptations, and GM's 2016 six-speed table also lists it without MIL. Allison 1000 checks for a current error of 0.5 A or more within 250 ms windows (Type A). In GM's CVT, B controls the primary pulley: a pressure error above 500 kPa steady or 1,500 kPa transient, confirmed by a ratio error for 5 s, sets a Type A code. Electrical faults of B are P0964, P0966 and P0967. Symptoms range from none to rough 3rd, 5th or reverse, or CVT ratio problems.
P0965 at a glance

- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0965
- Rough or delayed 3rd, 5th or reverse engagement
- CVT ratio fluctuates, engine speed flares
- Often no warning light on six-speed applications
Common causes of P0965
- Most likelyWorn or internally faulty solenoid, current no longer matches the command
- PossibleDebris sticking the solenoid or its regulator valve
- PossibleInternal leak in the CVT primary pulley circuit
- Less likelyHigh resistance in connector or pass-through
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0965 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. |
| 65 | The exact fault in that area. |
What to do next
- Note P0965 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 P0965
What does P0965 mean?
P0965 means "Pressure Control Solenoid B Control Circuit Range/Performance". Performance fault of pressure control solenoid B: wiring is intact, but current or resulting pressure does not match the command. It is a generic code, so it means the same on every make.
Is it safe to drive with P0965?
Drive gently and only to a workshop. With P0965 the car can go into limp mode (reduced power) to protect itself.
Will P0965 fail an emissions test?
Yes, it can. P0965 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 P0965 to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P0965 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
