How serious is the code?
The P0907 diagnostic code is actually quite serious, as without the information it provides, a number of serious driving problems can occur.
Symptoms
Symptoms of a P0907 include:
- The engine refuses to start
- Erratic shifting pattern
- Delayed and/or hard shifts
- Cruise control no longer working properly
Causes
- Misalignment of the gate select position sensor
- Shift linkage out of adjustment
- Faulty gate select position sensor
How to diagnose the code?
Often, the gate select position sensor can become misaligned after transmission repairs have been performed. So, when trying to diagnose the cause of a P0907 OBDII fault code, it is important to check the GSP sensor adjustment. It may also be necessary to check the shift linkage.
What repairs will fix P0907?
- Adjust the gate select position sensor
- Adjust the shift linkage
- Replace the GSP sensor
