Hi Lisa, The fault codes which are stored and displayed from the management system in the vehicle indicate defects which need attending to. Once the defects have been rectified the codes should be erased via the scanner and the vehicle should be derivable. If the anti theft codes have been erased and the workshop does not have the reset equipment, they may be hoping that they will reset by leaving the battery disconnected for a period of time. They may be lucky, but I'm doubtful. Best that they should call the agent and have it reset. There is no delay! Regards John

SOURCE: my 1996 grand am ,pontiac fail inspection due to

Here's a site to view what the part looks like, it's about $40. This info is assuming you have the 3.1 V-6, not sure if you have the 4 cyl. There is a charcoal canister that stores gas vapors so they won't be released into the atmosphere. These stored vapors are diverted to be burned by the engine. A defective purge solenoid valve won't allow the vapors to be burned, and the canister will eventually fill with gas. I changed one some time ago, and don't remember too well the procedure, but I believe it's just 1 or 2 bolts mounted on the upper engine area, I think it's on one of the valve covers, and a plug in (electrical). When you purchase the part, the parts store should be able to tell you the exact location. I remember the canister itself is under the coolant recovery tank. If you can see it (I seem to remember it was hidden) you can try to follow connections to the purge solenoid valve. Hope this helps, sorry to be somewhat vague, it's been a while since I changed it!

Normally you would have it scanned find out what the problem is and fix it then with the same scanner erase the code which would turn off your light but if you dont fix the problem the lights just going to come back on.There are two ways to clear the codes the best is with the scanner the other is disconnecting the battery for a couple of minutes.

2000 Pontiac grand am keep getting trouble code 113 air intake sensor high temp

If you have replaced the sensor then you will need to reset the cpu with a fault reader or the fault will continually reappear. If you have done that then if you have used an aftermarket unit to save money then some OEM computers will not correctly read the new unit and so will put up the fault code.

My 02 grand am gt is acting up engine light is on went to autoparts store to get it checked out it threw codes p1404, p0404 and p0300 i already changed the egr valve twice and it wont help can someone plz...

code p0404 refers to Exhaust gas recirculation system (EGR)--range performance problem--- causes---hose leakage--wiring---EGR valve/solenoid
code p0300 refers to random/multiple cylinder/s ---misfire detected.---causes---spark plugs---ht leads---injectors--ignition coils---low compression ---wiring. Remember it is best to use genuine sensors/solenoids as the cpu is set to them. Try changing the egr solenoid

Why is my Grand Prix surging/stalling when ideling?

If you did not disconnect the battery and drain the voltage from the ECM, it could be using old settings when the problem existed.
When a problem occurs, the computer tries to correct it or find new settings to work around the problem. When you fix a problem you have to clear the codes and sometimes erase the memory from the computer to allow it to start back at the factory settings.
When you disconnect something and the check engine light comes on, the computer goes into limp mode and uses values for the sensors preset by the factory. The car will almost always run rich to ensure the driver can get back to a place for repairs.

How do i reset the computer in my 2005 pontiac grand prix

If you need to clear the codes after changing something where the check engine light had been on you will need to get with someone or a shop that has the right diagnostic tool to reset it. Unhooking the battery won't do it.
