ABS and wheel hub


Recommended Posts

I'm getting code TC0027 and my ABS light is on. Sometimes it will come back if I wash the car or with some stroke of luck. Nice to have 1st gear back when it does come back. It's short lived when it does come back as I get may anywhere from 20 meters - 1km of distance before the ABS light shows.

Anyways, i will get the harness looked at, but does anyone know the GM/ACdelco part number?

The speed sensor connector for the left front wheel is loose or off, probably. If you need the sensor, it's changeable without a new hub.
