A couple weeks ago my car would randomly throw on these three lights but when I shut the car off they would go away for a couple days. I don’t notice any difference with how the car drives but the MPG has gotten better over the past couple months which makes me wonder if it is operating in all wheel drive or not. I got new tires and the car aligned at the end of the summer and I didn’t put runflats on it again. I recalibrated the wheel speed sensor on the scanner so I’m hoping this fixes the issue. Was wondering if anyone else has seen this. Hoping it’s not the TC.

Are those ALL the codes youre getting? Search the forums for “trifecta” this is usually caused by a faulty wheel speed sensor but you should have a specific code for those

Yep I got similar a while ago. Eventually the lights stayed on full time and now I have no abs or awd- pulled the sensor and it had been shaved down by the tone ring, which is likely swollen due to rust underneath it on the axle.

I plan to get a new axle by new years', can let you know how it goes. Remind me if I forget.

My other option is to cut off the old tone ring and wire wheel the rust, carefully reinstall a new tone ring from Amazon (they're not sold separately, officially)... There are youtube vids... But it's an old axle anyway, so I might as well just refresh it and save the potential headache.


Please keep us updated too, if you remember.
