Hi all,
I'm new here.
I have a 2005 Impala 3.4 with about 150k miles on it.
Recently when I start the car and either back up and put it in gear forward, or take off from a stop forward. Wheels straight or turned (either direction). Light throttle, dry pavement or dirt ( My driveway is gravel). The traction control kicks in and the light comes on. Twice now I've had a message that read Service traction system. (shut the car off and restart, No message).
I searched the archives and saw people talk about a sensor on each side that might have a bad connection. Or maybe bad bearings.
Where are the sensors located? And am I on the right track?

TIA,

Glenn

Check the connections behind the wheel, kind of by the strut. Un snap them and clean the
connections. Hopefully it's that simple, if not go to plan b.

Ummm.... Plan b? What would be the next step if not the connections? Can you replace the sensor?

Thanks for the heads up on where to find the connection though. I really appreciate it.

I have had the harness replaced because of a broken wire inside. I noticed it first after I went through an automatic car wash. The dealer said water tends to get in there and cause problems.

I promised to NEVER wash it again:-)

It is not usually the sensor. It is the same sensor/wire assemble as your ABS system uses. You'll find it running along your lower control arm, a-frame I guess. It will trace back up front under the radiator and tie into the cars electrical. From what I can tell, the dealer just spliced into just past the suspension control arm and replaced with all new. I bet a dealer will know exactly what the p/n is.
