P0967Pressure Control Solenoid B Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Pressure control solenoid B circuit high: a short to voltage, and on GM six-speeds also an open, since they have no P0964. 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 gearbox (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.
- What you may notice
- MIL on, limp mode in a fixed gear
- Harsh engagements at maximum line pressure
- Dual-clutch gearbox loses the even gears
- Likely causes
- LikelyOpen coil or poor connection (reported as high on GM six-speeds)
- PossibleControl wire shorted to a supply voltage
- PossibleDamaged or contaminated transmission connector
- RareFaulty output stage in the control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
