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.
How Serious is the Code?
A P2795 diagnostic trouble code tells you that there is a problem with the way the ECU sees the selected gear from the shifter. This can cause a number of transmission problems like slipping, abrupt shifts and it might not even go into gear.
Symptoms of a P2795 include:
- Unusually abrupt shifts
- Slipping between gears
- Delayed shifts
- Failed gear engagement
- Poor performance
- Limp Mode
- Damaged wiring/connectors
- Failed shifter assembly or components
- Failed/misadjusted transmission range sensor
How to Diagnose the Code?
When trying to diagnose a P2795 OBDII trouble code, it’s important to look at the condition of the wiring and connectors going from the transmission wiring harness to the shifter. The shifter itself may also need to be checked, along with the transmission range sensor (which may be out of adjustment).
What Repairs Will Fix P2795?
- Repair/replace damaged wiring or connectors
- Replace shifter assembly
- Adjust or replace transmission range sensor
