When you place your automated manual/semi automatic transmission shifter into gear, a sensor tells the TCM what gear you have selected. It then uses an electric motor to activate that gear. If the shift position sensor/transmission position sensor is not performing according to the preset parameters, a P0915 DTC will be saved.
How Serious is the Code?
The P0915 diagnostic trouble code is extremely serious, because the transmission problems that cause it can lead to an inoperable vehicle if you can’t put it into gear.
Symptoms of a P0915 include:
- Harsh, erratic or delayed shifts
- Transmission will not go into gear
- Wiring damage
- Broken/corroded connectors
- Faulty sensor
How to Diagnose the Code?
In order to properly diagnose a P0915 OBDII trouble code, a series of electrical and mechanical tests will have to be performed. However, the technician will need to be using the manufacturer’s specific diagnostic process.
