Hello and welcome to FixYa!

This warning serves as like a maintenance warning. It can just be a simple oil and filter change. Not a big deal but definitely you need to have an oil change.

Hope this helps and thank you for using FixYa! Have a good one!

the check engine light alerts you that there are problems. There will be a code or codes stored in the engines computer. You can retrieve these codes one of three ways.

1. call your local auto parts store. Many times they will do this for free.

2. buy an inexpensive code reader. Available just about anywhere that has an automotive department. They will start at about $50.

3. Bring it in to a shop to have a check engine light diagnostic done.

Once you know the code you can then start to focus on a repair. Once a repair is made the codes will be cleared and the check engine light will turn off. If you do not make the repairs the light will not stay off. It will continue to come on and stay on until the proper repair is made.

the only way to clear the faults is with a scan tool.they can be bought for cheap and work on all obd cars

should have two lights check engine and service engine soon.check engine means there is a malfunction.service soon is reprogrammable,when you change you oil. check you owners manual for reset.

I just put in new fron pads in my 2000 buick century and the track off and the anti lock brake light and the service engine soon stays on

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.

TAKE IT TO AN AUTO ZONE & THEY WILL RUN A SCAN ON IT & TELL YOU WHAT THE CODE IT IS, THEN YOU CAN REPLACE WHAT PART YOU NEED.

most any sensor going bad can cause the check engine light to come on,try disconnecting the posative battery cable for 15 seconds ,then put it back on,will reset the codes, or take it to auto zone,they will test your computer for codes at no charge to you.i had a venture van my was ox. sensor. thanks robert b.
