A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- The shift cable is adjusted wrongly
- The selector position switch on the transmission
- Sensor connector or wiring: corrosion, an open circuit, a chafed wire
What you can do yourself
- The dashboard may not show the gear, the engine may not start in P or N, and shifts may be harsh. You can drive gently and not far.
- Check that the lever position matches the letter on the dashboard in every position: if not, adjust the shift cable.
- Check the connectors on the transmission case: oil or water in a connector is a common cause.
Stop and don’t drive on if:
- The Check Engine light is flashing
- The temperature gauge is in the red or the overheating light is on
- The red oil pressure light is on
- Smoke from under the bonnet, a burning or petrol smell
- Strong jerking, knocking from the engine, or the car barely moves
OOleg’s tip: check the connector
Often the cause is simple — there is no contact in the connector (plug). Look at the connector from the back: remove the rubber seal and you will see whether a wire is corroded or has come off completely. Corrosion shows up as green deposits. Ideally, gently pull each wire towards you one at a time: a sound wire stays in place, while a corroded one simply comes off — it needs to be repaired.
Unplug and inspect connectors with the ignition off.

This is the meaning on GM 6T70 and 6T75 transmissions (GM bulletin PI0269B: Equinox, Malibu, Traverse, Captiva Sport 2009–2011). This is the GM meaning (Chevrolet, Cadillac, GMC). On other makes this number means something else: if your car isn’t made by GM, change the make at the top.
