Car Forum / Chevrolet / Chevrolet Malibu / February 2004Engine Light - Could it be associated with cold weather?
My engine light just started coming on. It comes on as soon as the car is started (along with all of the other warning lights), but it does not turn off. It may be a coincidence, but it was -40 when I noticed the problem. This may be another red herring, but for the past month, I would say fuel economy has been about 25% lower than expected. Any thoughts? Chris >>My engine light just started coming on.

Mine came on awhile ago, and it turned out to be a faulty fuel pressure sensor. My fuel economy has dropped as well...the air is too cold for the engines to work optimally I'm guessing. Once the temp goes back up to reasonable, the mileage will likely go up as well. Re: Engine Light - Could it be associated with cold weather?

The only way to know for sure is to scan for codes.....The temp might have somthing to do with it but its unlikely...First we need codes to be able to determine what the problem really is.. Steve C I know that some cars have a "cheat" method of determining the engine codes without the fancy monitors you plug in. Is there a "cheat" method for a Malibu?

Steve C The engine light went out today. I changed the air filter (it didn't appear too bad). I also opened the gas tank (I've had this cause one of the lights to go on before....). I have no idea if this is why the light went out, but I'm thankful none-the-less.

At first we thought it might have something to do with opening the gas cap. Quite a mystery. Anyway, it finally stayed on and we found out the EGR SOLENOID had to be replaced....$525.00!!

This is why we need the codes...The gas cap is part of the EVAP system and the EGR is part of the emissions...Both of which has different sets of codes....Sometimes its best to just pay someone to pull out the codes then fix it your self then .....Makes life alot easier..
