If your vehicle has a manual shift function on its automatic transmission, you will be able to manually control gear shifts by placing the gear lever in a special gate next to the PRNDL labels. However, if there is a problem with the electrical circuit that allows this to happen, a DTC P0950 will be recorded.
How severe is the code?
Having a diagnostic code P0950 will not significantly impact the vehicle’s driving, nor cause internal damage. However, you will likely not be able to manually shift the transmission.
Symptoms
Symptoms of a P0950 include:
- The manual shift function is disabled
Causes
- Damaged wiring or connectors
- Failure of the shift switch
How to diagnose the code?
An OBDII trouble code P0950 is often caused by damaged wiring or corroded connectors, due to spilled fluids around the gear lever. Therefore, all cables and connectors around the shift mechanism should be checked for signs of damage and corrosion. The transmission shift switch itself should also be checked.
What repairs will fix P0950?
- Repair or replace damaged wiring and connectors
- Replace the transmission shift switch
