What P0992 means
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.

Symptoms of P0992
- Warning light depending on manufacturer calibration
- Harsh or delayed shifts
- Possible limp mode with a fixed gear
Common causes of P0992
- Most likelyOpen or damaged signal wire or connector to the switch
- PossiblePressure switch or sensor failed inside the valve body module
- Less likelyTransmission control module input fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0992 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 92 | The exact fault in that area. |
What to do next
- Note P0992 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0992
What does P0992 mean?
P0992 means "Transmission Fluid Pressure Sensor/Switch F Circuit". General circuit fault of a sixth transmission pressure sensor or switch, labelled F. It is a generic code, so it means the same on every make.
Is it safe to drive with P0992?
Drive gently and only to a workshop. With P0992 the car can go into limp mode (reduced power) to protect itself.
Will P0992 fail an emissions test?
Yes, it can. P0992 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0992 to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0992 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
