The gear shift position sensor/transmission position sensor tells the TCM and ECU what gear you have selected with the shifter. If there is a low voltage signal on the transmission shift position sensor circuit, a P0916 DTC will be saved.
How Serious is the Code?
The P0916 diagnostic trouble code is actually pretty serious, because it means the vehicle’s computer cannot tell what gear you are trying to select. When this happens, the transmission may shifting erratically. Or, it may not go into gear and all, which will leave you with an inoperable vehicle.
Symptoms of a P0916 include:
- Erratic, harsh or delayed shifts
- Transmission won’t engage gears
- Wiring damage
- Broken/corroded connectors
- Faulty sensor
How to Diagnose the Code?
Diagnosing a P0916 OBDII trouble code will require the manufacturer’s specific diagnostic procedure. But it generally involves a series of electrical and mechanical tests to determine which transmission parts are at fault.
