2003 vibe emission light

There are several monitors in your computer and whenever the computer is reset to turn off the check engine light, the monitors have to run a full cycle to show that they are good. Even though your check engine light might not be lit, the state will not pass emissions unless all drive cycles have been cleared. If you reset the check engine light, you might as well fix the error that caused it to light or you will not be able to pass the emission test. If there isn't an issue, you should be able to just drive for a couple of days for the cycles to complete.

If you disconnect the battery, you need to reset the security system. You need to find out why it didn't start when you came out of the store though, and for that you need an auto electrician with a pro grade scan tool computer.

Whenever power is completely removed from a vehicle (disconnect the battery), active trouble codes are erased and all system monitors are reset. This is primarily to prevent 'turning off' the check engine light just before emissions inspection. Most states require that all monitors (or a specific number of them) be in a 'ready' status.
For the monitors to 'pass' checks and attain a 'ready' status, specific conditions must be met, usually involving 'drive cycles'. Some system monitors will reset very quickly - one drive cycle or less. Some take longer - more drive cycles or other conditions (usually the evaporative emission cycle requires fuel be between 1/4 and 3/4 of a tank of fuel).
If your car recently had the battery disconnected or replaced, you may have to drive it a few more times to get all monitors into a 'ready' status. If the EGR (exhaust gas recirculation) monitor does not reset, check with a dealer or a good garage on what parameters must be met to reset this monitor.

you have to drive at least 125 miles to reset and cycle computer some try the drive cycles they dont always work but the following links show you how to perform them

Drive Cycle and Emissions Readiness Monitors

you probably can find a tech to do this for you but keep in mind that you will be paying for however long it takes for all the drive cycles to run.

The light could be blinking because you haven't driven it enough for it to register. Drive it for awhile and check again. If the light still blinks, you will need to know what code it has.

After tightening the gas cap, you will have to drive the car a few 'cycles' before the light goes off. If that doesn't work, have the trouble codes read to find out exactly what is wrong and causing the light to illuminate.

Clear the codes per factory specs, you must drive the car for at least a week normal driving in order for the computer to reset itself to have all sensors in ready mode to be scanned for emissions testing or it will fail emissions due to the computer sensors showing NOT READY MODE, which the mechanic may not tell you about in order to sell you services you don't need.

That code is "evaporative emission control system leakage. (evap. canister system)"

this code takes at least two drive cycles to set. You can try to reset the engine light and emission computer and clear the code and see if the code resets. If it stays clear, it was probably a spurious code. To reset the engine light and emission computer, pull the No. 13 "clock/backup" (7.5A) fuse in the front passenger's kick panel fuse box. Wait at least 10 seconds. Put the fuse back in. This should put the check engine light out. If the light comes back on after two drive cycles (that is; start, run for a while, turn off X 2) have it checked out by a mechanic.

for more safe u need to take ur car for a delar or garage but it cuold be leak from the fuel tank or maybe from the evap system
thanx for asking us
