P2795: Gear Shift Direction Circuit High OBD-II Trouble Code

When the ECU sees what gear you have selected with the shifter, it sets the engine timing, fuel system and transmission shift strategy. If the computer thinks that you have selected the wrong gear because the voltage on the gear shift direction circuit is unusually high, a P2795 DTC will be set.

Because the vehicle’s Transmission Control Module (TCM) monitors the Gear Shift Direction Circuit signal. The TCM sets the OBDII code when the Gear Shift Direction Circuit Circuit signal is out of factory specifications.
