Your leaking gas fumes into the atmosphere. Its a health risk. All cars leak a little. Even new ones. Your leak is larger than your computer will allow. If the mechanic did not recommend a new fuel cap that would be my first choice since you can do that yourself for about 10 bucks.

Code 0456

You mean check engine light? If so, the P0456 code is an emmisions leak code. You will need to take the vehicle to a qualified repair facility and have them run an emmisions leakage test on it.

Very low miles 1995 Hyundai ELANTRA 1800 cc 16 dohc. CHECK ENGINE LIGHT frequently comes on. Stop engine, retart after light goes off...sometimes goes for hundred miles and three times new timing belt...

If the timing belt keeps breaking and bending valves, the timing belt and cylinder head repair is not being done correctly. It's as simple as that. Are you changing the tensioner and idler pullies when replacing the belt? Is it timed correctly? Was the timing belt tension adjusted properly? Were the cam journals checked for damage? If not, you are asking for another belt failure.

If you want to know why the check engine light is coming on, you will have to ask your engine computer. Every time the light comes on it is storing a fault code to tell you why. You must scan your engine control module to retrieve the fault code(s) so you can get it properly diagnosed and repaired.

Why is the check light on on my 2002 pontiac sunfire. and when i take the battery cables off the light comes off but then comes back on in a few days

There is a continuing problem occuring. You need to hook up an OB11 meter to the port under the dash to access the info needed to make the necessary repair. Often it is a simple thing like a leaking gas cap i.e. an emmisions code. OB11's are relatively cheap from $50-$300. Bottom end ones will work fine. Good luck!

Engine light remains on.

Their is a fault with the electronics on the engine. This will bring up the engine light, you will need to see a dealer with an electronics reader to find out what this fault code. Most dealers will read it for free, and then charge for the repair from that point. If it is an orange light, just get it to a dealer when you are able to. If it is a red light, avoid driving it and get to a dealer ASAP. this will prevent any possible engine damage.

How do i turn off a check engine light on my 2007 gmc yukon

The dealer will have to do this for you. If you had a problem and it is fixed, the light will go out after several days of use, if the light doesn't go out after a while, then you still have a problem and the dealer will have to help you read the codes and come up with a solution. Most of the time a check engine light will be set off by faulty emmission sensors, or some type of failure in the emmision controls.

I need a ecm software upgrade for my 2007 kia sportage, cannot be repaired for a few days. Can i still drive it?

This depends on what the problem is, if the car runs good and there are no preformance problems or overheating then i would say yes you can drive, if its just an emmisions upgrade or check engine light then go ahead and drive, also if its a dealer recall yes drive it.

Emissions warning light stays illuminated while driving vehicle is a holden vectra 2001 and not oldsmobile as below. could not find a listing for holden.

The warning light has two states. A blinking light indicates a critical problem with gaseous emissions from the engine that is likely to cause permenant damage to the engine, exhaust sytem or catalytic converter. A blinking light must be remedied immediately, and the car should not be driven in this state, at the risk of causing serious and permenant damage to the engine, exhaust and/or catalytic converter. Repairing or replacing these parts can be extremely expensive. A reputable garage or a Vauxall/Opel garage should be able to diagnose and repair the problem.

A solid (unblinking) light indicates a non-critical fault in the emmisions exhaust system. Many faults are covered by this light including failures in emssions sensors, temperature sensors and a variety of other parts. This usually results in a higher than average amount of environmentally harmful pollutants being expelled from the car, loss of power and/or gradual damage to the engine, exhaust and catalytic converter. While the car can still be driven with a non-critical emmisions problem, it is highly recommended that the fault is diagnosed and repaired at a reputable garage or Vauxhall/Opel garage.

Anti-lock brakes and 4wd lights are on

This is likely a wheel sensor problem, which when it fails, the car goes into a limp mode. Allowing you to drive it safely until you can get it repaired.

well this old trick might work.disconnect your battery for about 5 minutes and hook it back up,that work for me.or you can take it to an autozone and they have a code reader to read and turn off the engine light.let me if the check engine light is on it wont pass emissions.
