One or more of the engine electrical plugs is now wet and shorting out the circuits.
Without taking each and every plug apart and drying with a hair dryer,,you are just going to have to wait this one out.

Trac off light on oldsmobile alero 2001


first and most important, check your oil level...make sure it is at full and is clear (not dark).

Your conditions normally suggest an electrical problem mostly seen if the battery and or alternator is not at full operating range. Try to get a digital voltmeter and measure the battery resting (not running), it should be about 12.4 volts or higher. With the engine running, it should read 13.9 to 14.7 volts. A cheap meter can be found for less than $10 and if you need to, go to a commercial auto parts store like Autozone, Advance auto or PepBoys and they will test your battery and alternator for free.

Check engine light, traction off, & winding out


my wife's car does the same. Changing the ignition switch will fix it, however i've changed them three times. my best advice would be get to rid of the alero. Lemmons is the best way to describe those cars. They are by far one of the poorest vehicles ever made and i will never buy another gm vehicle because of it.

My car has several lights on and im not sure why. I have 2001 olds alero with 125,000 miles on it. The service engine light and the anti- lock and abs lights come on and stay on here lately. any clues why?...


I'll try to answer these as asked.
1. check engine light is telling you that you have an emission control problem and needs to be scanned for codes.
2. The abs and traction control light are connected and when the abs sets a problem code it will turn both on , It also needs to be scanned for codes.
3. Having a tire that is a diffrent size or more worn than others will set the tire pressure lamp and it can be cleared by removing the fuse panel door on the side of the dash and holding the red button in with the key on engine off untill it flashes or beeps and goes out.

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.

Lights on for service engine soon anti lock and trac off


Id have to know what code has triggered the Service Engine Soon light in order to diagnose that. It could be related to the anti-lock and traction control system being off or it could be something separate.

That said, it is common for the anti-lock and traction control to be turned off if one or more of the wheel speed sensors goes bad. In some cases the wheel speed sensors are separate from the wheel bearings but in your case I believe they are integrated with the wheel bearing, so in order to replace the sensor you have to replace the wheel bearing.

In order to know which wheel bearing is the culprit, you'd have to have the car hooked up to a scan tool capable of reading ABS codes.

Anti-Lock and Trac Off lights are lit on my 1999 Alero, as well. They usually come on after about 5 minutes of driving, but are not always on when I start the car.
