2001 Plymouth Neon?

Some states use a scanner to check OBDII (on board diagnostic II, a computer program thats sole function is to test the function of the emission systems) monitors to verify correct function and if a code is present, they will not pass you, other states use only a sample test ( test probe placed in the exhaust streem) , to verify emission levels, and then some areas use a mass emission test (IM240, total mass collection) to measure the actual weight and type of the emissions produced by a vehicle, so without knowing what type of test they will use it's hard to say if you will pass or not.

Simply taking the bulb out will not erase the code , and some testers check the function of the "tell tail" feature, a bulb check when first starting the vehicle. If you clear the code and try to drive directly to the test facility , and the site is looking at scan data, the OBDII monitors may not have had enough drive time to complete (typically take more than one drive cycle).

Disconnect the battery for a few minutes will reset the PCM and all the OBDII monitors, If the fault is an intermittent condition it will not reset until it's seen again by the PCM, if it is a hard code, the light will illuminate almost immediately. Most codes will require more that one failure event to keep the light illuminated for more that a single "trip cycle".

you could have someone use a scanner on it and turn the light off,but if the problem is still their it will automatically come back on again,other than taking the bulb out there is no way to turn it off without repairing the problem,i wish there was a quick way i could tell you to do this,but there isnt,good luck with it.

HAI,

I HAD THIS PROBLEM LAST WEEK,AFTER I GOT MY CAR WASHED IN STATION THE CHECK ENHINE LIGHT WAS ON.I WAS VERY SCARED AND IMMEDIATLY TOOK IT TO A WORKSHOP.THE MECHANIC TOLD ME TO CHANGE THE ENGINE OIL AND SEE IF IT GOES OFF.BUT IT DIDNT HAPPEN.THEN IT WAS TOO LATE IN THE EVENING AND MYSELF REMOVED FEW CONNECTORS IN THE BONNETT AND CLEANED WITH CONTACT CLEANER.THEN I REMOVED THE BATTERY CONNECTION AND REFIXED IT BACK SO THAT IT WILL GET RESETTED.AFTER THAT IT HAS NOT COME,U CAN TRY THIS.HOPE IT WILL WORK FOR U TOO.EXPECTING YOUR REPLY SOON.WITH REGARDS.

if you know some one that own an auto repair shop take it in and have them hook it up to the diagnostic computer and have them take it from there. just only if you know the person.
