: Tc light comes on

11-27-12, 12:59 PM
Randomly at speeds over 50 the traction control goes off and the light comes on. I can't turn it off. And while its on the engine makes a weird wirr sound and the car shifts weird. It randomly goes on and off at speeds above 50. Any ideas. I think its a wheel hub but in my experience with wheel hubs Tc light abs light and others also come on.

I would also suspect a bad wheel speed sensor which is a part of the hub assembly.

Could be intermittent enough to not throw a DTC to trigger a dumby light.

But what's possibly causing the weird shifting and noise that occurs when the light is on. Now at the same time the check engine light came on throwing a p0024 code. Wtf.

Funny i replaced my l rear hub and tc still comes on but i can accelerate past 80mph before i couldn't. But i think my differential is moving (just replaced bushing earlier this year) i will put it in the air and have someone check movement as i go thru pnrd. I say check mounts too hopefully it's the pass engine mount lol driver side os a pita

Mine started doing that over bumps or railroad crossings.
Was a bad wheel sensor also.
