What P0995 means
The signal of pressure sensor or switch F stays high: with a normally closed switch the contacts stay open, which looks like permanent pressure, or the wire is open or shorted to voltage. No manufacturer documents this use publicly. Hyundai/Genesis bulletins 17-AT-001-G and 21-AT-016HG list P0995 in their subject lines, but their tables pair it with Auto Shift Manual Mode Circuit (SBC), and 21-AT-016HG prints the DTC as P095500; this is a misprint for P0955 and does not count as a use of P0995. GM's matching switch E code P0990 is a Special No Trip without MIL; Saab's 9-4X text treats an open and a short to voltage alike as high. CARB requires such checks on transmission inputs. P0994 is the low side.

Symptoms of P0995
- Harsh or delayed shifts
- Shift adaptation frozen
- Possible limp mode
Common causes of P0995
- Most likelyOpen signal wire or unplugged connector
- PossibleSignal wire shorted to voltage
- PossibleSwitch stuck open inside the valve body module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0995 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. |
| 95 | The exact fault in that area. |
What to do next
- Note P0995 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 P0995
What does P0995 mean?
P0995 means "Transmission Fluid Pressure Sensor/Switch F Circuit High". The signal of pressure sensor or switch F stays high: with a normally closed switch the contacts stay open, which looks like permanent pressure, or the wire is open or shorted to voltage. It is a generic code, so it means the same on every make.
Is it safe to drive with P0995?
Drive gently and only to a workshop. With P0995 the car can go into limp mode (reduced power) to protect itself.
Will P0995 fail an emissions test?
Yes, it can. P0995 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 P0995 to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0995 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
