The transmission fluid pressure sensor F communicates the level of hydraulic pressure inside the transmission back to the ECU through a series of electrical pulses. If there is an unusually high-voltage signal coming along the transmission fluid pressure switch F circuit, a P0995 DTC will be saved.

How Serious is the Code?
Although it may seem like just a simple sensor, the transmission line pressure sensor actually helps the ECU to decide how to shift the transmission. So a P0995 diagnostic trouble code is very serious.
Symptoms
Symptoms of a P0995 include:
- Hard shifting
- Transmission fails to go into gear
- Limp Mode
Causes
- Dirty transmission fluid
- Low transmission fluid level
- Damaged wiring
- Corroded/broken connectors
- Transmission fluid pressure sensor/transmission line pressure sensor has failed
- Valve body issues
How to Diagnose the Code?
When trying to figure out what is causing a P0995 OBDII trouble code, it’s important to check the level and condition of the transmission fluid next, all of the wiring and connectors along the transmission wiring harness between the TFPS sensor and the ECU will also need to be checked for signs of damage and corrosion. The transmission fluid pressure sensor F itself should be checked at this point, if no problems have been found. If it works, then there is likely mechanical problem that is causing this OBD2 code.
