The gearshift reverse actuator responsible for helping you engage reverse when you move the shifter. If this vital component is not performing according to the preset parameters, a P0925 DTC will be saved.
How Serious is the Code?
If you’re unable to engage reverse when you need it, the P0925 diagnostic trouble code seriously impact the safety of your vehicle. So you should have these transmission problems diagnosed as soon as possible.
Symptoms of a P0925 include:
- Transmission behaves erratically
- Engaging or disengaging reverse becomes difficult or impossible
- Wiring/connector damage
- Gearshift reverse actuator has failed
- Gear guide real has become damaged
- Shift shaft has become damaged
- Internal mechanical failure
- ECU/TCM issues or failure
How to Diagnose the Code?
One of the first steps to diagnosing a P0925 OBDII trouble code, is to carefully inspect the wiring, connectors and relays. Gearshift reverse actuator itself will also need to be checked, along with the gear guide rail and shift shaft. Should no issues be found up to this point, further diagnosis of the transmission, ECU and TCM will be needed.
