Question about 1997 Buick LeSabre

2 Answers

How do I reset the check engine light? Auto Zone said it was a bad gas cap. I bought a new one & it still stayed on. They re-checked it and turned it off for me, but now it popped back up. Same reading. Car runs fantastic. Absolutely no problems. Ideas for how to reset?

    Thank you, Russ. I'll give that a try and see if it works. If I can't do it myself, do you have any idea how much it might cost to do that at a mechanic? Or with someone advertised as a mechanic on craigslist?

I know of 3 ways to clear it:
1. Disconect the battery
2. Use a computer(Autozone)
3. If the problem is really gone, it will go away on it's own after so many key cycles (used to be about 50 on my dodges). It usually takes about a week on my Buicks.

Should not need a new cap ? there is a vent in the tank that is controlled by the engine being started. underneath the back of the car there is a pipe that comes from the top of the petrol/diesel tank follow the pipe to the engine bay looking at the pipe looking for damage. in the engine bay it will go to a vacuum pipe with a valve on it. that would be the fault has 2 wire on it to say when it is open. on some models its electric controlled and have 4 wires. some times the part were it vents out can get blocked and the ecu will read it is closed. it is mostly down to dirt and grim blocking it up just will need a clean out.

Hello Reina.
It isn't going to hurt anything unless your fuel tank is leaking fuel. In which case you should get it fixed.
It could be a fuel cap and if it seems loose or worn you should replace it anyway. It may cure the problem.
It may take a while for the light to turn off though, as it will need to run the test and pass before it goes out.
If you need more help, leave a message and I will return to assist.

Lost gas cap and check engine light came on. got new gas cap but light won't go off.


Sometimes for this light to turn off you will need to reset the computer system that logged the code. Advance Auto and Auto Zone have a free service that will do this for you, they will also be able to tell you if the check engine light has logged a code for some other then the gas cap. Just go into Advance Auto or Auto Zone and say "Could you reset my check engine light for me?" they will grab their scanner tool and ask you to lead them to your vehicle, they will need to turn your car to the ON position but not start it.

Got numerous "tighten gas cap" messages. finally


computer is seeing a large evap leak. most common cause is gas cap left loose this is why it is throwing up that message. since you have already done that we know there is a leak somewhere else. look underr vehicle and should see a black rectangular box close to gas tank this is the evap canister check the lines hooked to this and just do a visual inspection of hoses see if one has come off. may need to have it checked out we have a machine that hooks into system and pressurizes with "smoke" the smoke leaks out of the problem area and helps diagnose .

Just disconnect the battery (negative terminal) and turn the headlight switch on for about 15 minutes. This should reset the PCM. Otherwise go to Advance and have them hookup the code reader and reset the codes. Thanks
