You need to diagnose and replace whatever is causing the problem and causing the ECU to give of that check engine signal. If possible have it hooked up to an OBD2 reader and find the error code. Then decode the error code and it will tell you what needs to be replaced.

I have a 2001 Oldsmobile Alero. What does it mean when the anti brake light, service engine soon, and traction off light comes on at the same time?


I am assuming its not the service engine soon light it is probably the service vehicle soon light, There are 2 lights service vehicle soon upper left side, and service engine soon upper right side.

When all these come on at the same time it is the wheel bearing sensor. Usually the wheel bearing needs to be replaced which houses the sensor. A sure way to check is to press your sls button by your shifter and see if the light goes out, If it does not, u will need to have a wheel bearing put in.

When I start my 2001 alero the anti-lock, traction light, service engine soon, service vehicle soon lights all stay on all the time. But my car seems to be running fine. Why is this?


the anti-lock and traction lights will come on together if there is a common problem with the two, since they are closely related. may be a wheel speed sensor or something similar. the service engine soon light indicates a problem with the engine computer, can be anything from an emission system problem or an engine performance problem. all of these lights can come on with no apparent running problems on the car. the service vehicle soon light is basically a maintenance reminder, an oil change light. take the car into a shop and have the codes read for these lights.
