This vehicle has just completed 126,000 miles. Recently the Service Engine Soon light illuminates in tandem with the Trac Off and ABS light. Any possible ideas of the cause? These warnings appear after a few miles into a journey.

Many Thanks

more than likely it is to do with a wheel speed sensor. but just to be safe you should take it someplace that can scan for abs and body codes then report back here with your findings.

If the engine and the abs/trac are connected being on i would say its prolly a tranny code possible a bad sensor. If their not connected then the abs light is prolly a speed sensor like eltatertoto said.
