If you just want to get through the smog test,they usually allow one monitor test to be incomplete and still pass.
If your area does,clear the codes and fill the fuel tank to the top.The other monitors should run and complete but the fuel tank monitor will not run with a full tank of gas so will not turn on the check engine light related to a tank vac leak.KEEP THE TANK FULL,and go get your smog test!

How can I reset the service engine soon light on a 2000 Oldsmobile Intrigue


Hi,
The service light is indicating there is a fault code either in the ECM or BCM system. The only way in which this can be switched off is to have these codes checked and cleared in these to control unit with a diagnostic tool.

If they forgot to tighten the hose clamps on the hose from the tank to the filler cap it could be setting it off. If they are all tight it was probably just the gas cap. The gas cap is usually ALWAYS the culprit. Let me know if this helps

the eec is the sensor for the evap system, either the gas cap is leakin or one of the hoses, the system is made to keep the gas tank at minus 1 lbs pressure, anything that disrupts this will send a message, could also be the fuel tank itself

Replaced o2 sensosor, SES light back on


If he used a "universal" O2 sensor, you could have a wiring problem. I had the exact same behavior on a Mazda MPV. The universal O2 sensors have to be crimped to the old sensor connector, which can cause problems. You can check the wiring closely, or insist that he use an OEM sensor, which will have the proper connector attached.

"Service enging soon" light stays on....


This could be a number of things causing this ...most common is that after you fill up the gas cap is not fully tightened...make sure it "clicks" 3 times while turning.The other common problem is that the gasket on the gas cap is old and thus does not seal the tank/fuel filler area...check with replacing the cap.If neither correct then you will need to bring to a service center or dealer to run a code check...maybe a bad O2 sensor or a code for the transmission.

Jeep Grand Cherokee Service engine light soon on


A loose gas cap will sometimes trigger the service light to come on.  Since this appears to have happened on multiple occasions I can assume that this is not the problem but may be associated with it.  The level of gas in the tank affects the amount of atmospheric pressure in the tank. There are multiple things that could set off the light, one being a loose or defective gas cap, and the other is a fuel vapor return valve.  I'm not sure of the exact type of fuel system you have so I cant give a more exact answer.  If you wanted to give something a shot before bringing it into the shop, you can simply replace the gas cap first, a very cheap try.
