The P0967 code indicates a Pressure Control Solenoid "B" Control Circuit High. This means the Transmission Control Module (TCM) has detected that the electrical signal to the "B" pressure control solenoid is higher than it should be, suggesting a short or a fault in the control circuit.
Common Causes
-
Faulty Pressure Control Solenoid: The "B" solenoid has failed internally, creating an electrical short.
-
Wiring/Connector Issues: Damaged, corroded, or loose wiring in the transmission harness is causing a voltage spike or short to ground.
-
Internal Transmission Contamination: Dirty or metal-filled transmission fluid can interfere with the solenoid's operation, causing it to draw excessive current.
-
TCM Fault: An internal failure within the Transmission Control Module itself is causing it to send incorrect voltage levels.
Signs to Watch For
-
Check Engine/Transmission Light: A warning will illuminate on your instrument cluster.
-
Harsh Shifting: The transmission may feel jerky or "slam" into gear during shifts.
-
Limp Mode: The transmission may stay locked in a single gear (usually 2nd or 3rd) to prevent damage.
-
Poor Acceleration: The vehicle may struggle to gain speed or hesitate when you step on the gas.
Diagnostic Tip: Inspect the transmission fluid color and smell. If it looks dark or smells burnt, the transmission may have internal mechanical damage that is causing the electrical solenoid failure.
