What P0967 means
Pressure control solenoid B circuit high: a short to voltage, and on GM six-speeds also an open, since they have no P0964.
How the engine computer detects it
For the Saab 9-4X 6T70, where B is clutch pressure solenoid 2 for the 3-5-reverse clutch, the module needs 1 s, stores a Type A code and limits the transmission to reverse and 3rd gear at maximum line pressure; GM's 2018 six-speed table uses 0.3 s and one trip. GM's 8-speed (clutch 2), the 9- and 10-speeds, Allison 1000 (power short within 75 ms) and GM's dual-clutch transmission (even-clutch valve) report the same fault on their solenoid B. Ford does not use it. Siblings: P0964 open, P0966 low, P0965 performance. Repairs usually involve the solenoid body or valve body module.
Written from public technical sources and not yet checked by a mechanic. How we write these pages
Symptoms
- MIL on, limp mode in a fixed gear
- Harsh engagements at maximum line pressure
- Dual-clutch transmission loses the even gears
Common causes
- Open coil or poor connection (reported as high on GM six-speeds) Most likely
- Control wire shorted to a supply voltage Possible
- Damaged or contaminated transmission connector Possible
- Faulty output stage in the control module Less likely
How to diagnose P0967
- Read every stored code with an OBD-II scanner. If misfire or fuel trim codes are there too, fix those first: they often cause this one.
- Inspect the parts involved: pressure control solenoid b, wiring harness, tcm.
- Work through the causes above from most to least likely, cheapest checks first.
- Clear the code and drive a full drive cycle to confirm the repair held.

Questions drivers ask
Can I drive with code P0967?
Drive gently and only as far as you need to. The engine computer may limit power to protect the engine, so avoid highways and heavy traffic until it's fixed. If the check engine light starts flashing, pull over.
Will my car pass an emissions inspection with P0967?
Probably not in states that test vehicles with an OBD-II scan: an emissions-related code that keeps the check engine light on is usually an automatic fail. Rules differ by state and county, so check yours.
