P0996Transmission Fluid Pressure Sensor/Switch F Circuit Intermittent
- Generic OBD-II code · Powertrain
- How the car detects it
- The signal of pressure sensor or switch F drops out or flickers for short moments without staying low or high. No manufacturer documents this code publicly, and no transmission with a sixth pressure switch was found: GM's six-speeds end at switch 5 (E), Mitsubishi's 2019 six-speed uses letters B, D and E. Because such switches are thin film-and-piston units inside the valve body module, as Sonnax shows, debris or a delaminated film can make the contact chatter, and connector or harness faults do the same electrically. CARB requires transmission inputs to be checked for circuit faults; an intermittent code is the slot for faults too short to set P0994 or P0995. Expect occasional rough shifts, often without a warning light.
