ABS, Traction Control, and Check Engine Lights

Recommended Posts

Im back with another new issue on my wife's Edge. We recently replaced the passenger side axle due to a broken tone ring and recently had a coolant leak due to faulty radiator fans.

 

The new issue is is that the ABS, Traction Control, and Check Engine lights all come on while she is driving on the highway. It only happens at highway speeds around 70MPH. They all go away once she parks and comes back later. Driving on roads at less than high way speeds the lights never come on. So far we havent been able to tie it to hitting bumps.

 

Any ideas? My first thought was a wheel bearing or wheel speed sensor or another bad tone ring somewhere.

Not a wheel bearing. If it's intermittent then I would suspect the wheel speed sensor wiring. Check for loose things or chafed wires.

I was thinking the same thing, but if it was loose wires bumps would also set it off. It currently seems to be speed related.

You should pull the codes to see what the check engine light represents. That she's losing ABS and traction comtrol could be isolated to one or more sensor's triggered by speed. (These systems are very complex interconnected).

I'm thinking wind would be pushing the wires in a different direction (horizontal?) than a bump (vertical).

 

Hard to say though. Maybe the sensor is flaky and can't keep up with the speed above 70.
