I've had that roblem twice for my car, they changed 2 sensors, first was the crankshaft position sensor and the other was the mass air sensor. my car was still under warranty so it didn't cost me but if it weren't then the whole thing would have cost me about $600.

Check Engine Light On, Accompanied by the Gas Cap Warning Light


I'm not sure what you mean by "kick". But the gas cap light will not affect the performance of the engine or transmission.
I would recommend having the computer scanned for trouble codes next.
The gas cap light means the computer has found a vac leak in the venting system for the gas tank and it could be allowing fumes into the air. The most common reason is the gas cap has been left off or is not tight. But if you have replaced it the problem is elsewhere in the venting system. The trouble code stored for the check engine light would point a mechanic in the direction of the actual problem.

Check light on for kia opirus 2008


Scanned the PCM; If the check-engine light comes on, here are some tips on what you should do:
- Look for a serious problem that requires immediate attention. Check your dashboard gauges and lights for indications of low oil pressure or overheating. These conditions mean you should pull over and shut off the engine as soon as you can find a safe place to do so. On some cars, a yellow "check engine" means investigate the problem, while a red "check engine" means stop right now.
- Try tightening your gas cap. This often solves the problem. Keep in mind that it may take several trips before the light resets. Some vehicles have a separate indicator that warns of a loose gas cap before the condition sets off the "check engine" light.
- Reduce speed and load. If the "check engine" light is blinking or you notice any serious performance problems, such as a loss of power, reduce your speed and try to reduce the load on the engine. For example, it would be a good idea to stop towing a trailer. Have the car checked as soon as possible to prevent expensive damage.
- Contact OnStar, if available. If you have a 1997 or later General Motors vehicle equipped with OnStar and an active OnStar subscription, contact an advisor who can read the trouble code remotely and advise you about what to do.
- Have the code read and the problem fixed. If you want to diagnose the malfunction yourself, you can buy a scan tool at most auto parts stores. Prices range from about $40 to several hundred, depending on the model and the features. The tools come with instructions on how to hook them up and decipher the codes. But unless you have a good knowledge of automotive diagnostics, you're probably better off taking the vehicle to a professional. Some automotive parts stores will read and interpret the code for you without charge. Unless there is an easy fix, they may simply refer you to a mechanic.
- Don't go for a state emissions test. In a late-model car, an illuminated "check engine" light probably is a sure sign your car will fail the test. In some states, it's an automatic failure, even if the problem was nothing more than a loose gas cap. By the way, don't bother trying to fool the inspection station by disconnecting the battery or using any other method to erase the trouble code and turn off the "check engine" light. Your vehicle's computer will let the inspection station know that its codes have been erased, and you'll just have to go back again.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

I have a 1999 Saturn sc3. It was fine until the hurricane this past weekend. As soon as I turned the car on, the l"Service Engine Soon" light came on. I am wondering if it is safe to drive or...


The Service Engine soon light indicates that something is likely wrong with your emissions system. It could be any number of things but it is OK to drive to a repair shop or parts shop to get the codes read. Some of these issues can cause damage if you don't get the vehicle repaired soon but you can drive it a little bit (you won't need to get it towed).
I would recommend an Autozone or Pep Boys to get the code read as it may be something as simple as replacing the gas cap.

I think someone loosened my gas cap on my 07 silverado, would like to know if there is a way to reset engine light.


Once you tighten the gas cap the engine light will reset itself after it has gone threw the necessary drive cycles, but only if the problem has been fixed. So yes if the check engine light came on for the reason of a loose gas cap, once you tighten it it will go off on its own.

I have the same car and if the gas cap is loos for any reason the service engine light will come on so check that. If it is it will turn off in a few days after you tighten it.

I need a maual for a 2003 Suzuki Limited Edition XL-7


You might be mistaken about the check engine light. I have done all the oil changes on my wife's 2003 XL7 and never once have I had to reset anything. If you mean the SERVICE ENGINE SOON lamp, that means the computer detected a problem with the emission control (or someone didn't put the gas cap back on correctly during the last trip to the gas station). Check the gas cap 1st, just take it off and put it back on, making sure to give it a few "clicks" past the stop. If after a few days the light doesn't go out head over to a suzuki dealership and have your ECS checked out.
