Where is odometer cable located at on a '02 Pontiac Gran Prix?

Question

Just purchased this car w/ salvage title and the odometer dont work. Possibly disconnected by previous owner. No $$$ to pay shop to fix, so I'm going to try to fix myself.

Answer 1

Your ponitac doesn't have a cable. It's completely electronic.

there is a sensor that is located on your drivetrain, more than likely near the final drive gear, that registers speed and sends it to your PCM/ECM and from there to your instrument panel.

The sensor is located on the top side of the tranny case. I can't tell if it's on the top left or the top right.

Answer 2

No cable its a sensor on the trans .Sensor sends info to PCM form PCM goes to cluster control module then to int.cluster .Start with replacing the sensor after that take it to a repair shop because for them everything get pricey
