P0992Transmission Fluid Pressure Sensor/Switch F Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- General circuit fault of a sixth transmission pressure sensor or switch, labelled F. No manufacturer documents this code publicly, and no gearbox with a switch F was found. GM's six-speeds stop at TFP switch 5 (letter E, P0989/P0990), and Mitsubishi's 2019 six-speed monitors its 2-6 brake, high clutch and low-reverse brake switches under P0846, P0876 and P0988, which are letters B, D and E. Pressure switches like these sit in the valve body module and tell the module which clutch is applied; Sonnax describes them as normally closed film-and-piston switches. P0992 would be the code for an open or implausible circuit without a low/high split, as CARB requires circuit checks on transmission inputs. Range/performance, low, high and intermittent are P0993 to P0996.
- What you may notice
- Warning light depending on manufacturer calibration
- Harsh or delayed shifts
- Possible limp mode with a fixed gear
- Likely causes
- LikelyOpen or damaged signal wire or connector to the switch
- PossiblePressure switch or sensor failed inside the valve body module
- RareTransmission control module input fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
