Your car has a computer that is telling you your gas cap needs to be tightened or replaced. All newer cars have this for pollution control. Google your make and put in check gas cap ant it will explain all about it. If this sensor is not reset then here it won't pas an E TEST. which is the law in Ontario.

What does the orange light that shapes like an engine on the dash panel mean?

It is your check engine light. U can go to a local auto parts store and they will plug in a code reader that will tell you why the light is on. On newer cars, always check your gas cap and make sure it is tight as a loose cap will give an emissions control code and set the light off. Hope this helps

My exhaust system warning light is on. What could this mean? I have just had the oil changed and use regular gas. I always tightened the gas cap fully after several "clicks". thanks

could be one of two things either your cat is failing or the lamba sensor on the cat which measures gasses in the exhaust system has failed which will illuminate the light on the dash

this happens because most time most people forget to tighten the Gas cap after fueling the vehicle. It is also mentioned in side the Gas cap compartment.
pls turn the Gas cap atleast three time with the clicking noise loud enough to turn head of the guy fueling by next pump.

Now, once u get these lights on what to do? well it should disappear next morning when u r starting it to get back to work. if now, find ur self a driveway or a road which is quite a bit of uphill or downhill and park the car there, turn the engine off, keys out and wait for 5 minutes. get back in and enjoy the clear dash.

My service engine light on the dash has come on and stayed on. We took it in to have it hooked up to find out why the light is on. The guy told us there might be a fuse out some where because when he...

just make sure your gas cap is on tight there is no fuse...i wish everything could be fixed with fuse..the gas cap is the number one trouble code for the light just drive it a couple of miles and see what happens.they have a rubber seal that once warn has air leak making light come on good luck

Light on my dashboard

ford taurus's are well known for this. the seal on the gas cap goes bad. before you replace the gas cap make sure when you close the gas cap you are turning it at least 5 clicks. if light stays on get a new gas cap. they are easy to install all you need to do is remove the gas cap.remove the gas cap strap. put ******** the new cap, close cap and turn 5 clicks. not clicking 5 time can set a p400 or p401 evap code causing the check enging /ses light to come on.
