Hi,

I have a 2001 S40 1.6

Last week when the engine was started for a time,ckeck engine light comes on. I tried to stop and restart engine and the check engine light still on. When I stop engine for a long time, check engine light comes off.

Today check engine light comes on again.

I ask to my volvo dealer and tells that nothihg happends if the check engine light turns off.

Annyone knows what's happening to my volvo ?

Thank's, and sorry for my english

Your oxygen sensors may be in need of replacement. It's one of the most common reasons for the Check Engine light.

The Check Engine light tells you that there's a problem with a part that is related to emissions control.

Thank's matthew1 for your quick answer.

My dealer is too busy , and tells me that i have to wait next week to they can check my car.

They says that are more than 300 different failures can set on check engine light , and to check all sensors they need at least 2 hours.

Next week i tell you more.

It takes actually 5 minutes. Take it to an auto parts store (call first) and ask if they'll read the codes. Ususally free.

Write them down then post them back to this thread and we'll go from there.
