Most any ODB-II scanner should be able to clear the code. Has your shop connected a scanner to scan for codes?

Ditto...if your shop can read the OBD II codes...then they should be able to reset the SES light. If they did, and the light returned...it means that there's still an issue. Reread the codes to see what it says this time. Even if they didn't reset the light...if the issue was fixed, or even went away on it's own...after a few drive cycles where the fault is no longer present...the light will turn itself off.

If you don't have a scanner/reader...I believe (in your state) that you can take your car to the local AutoZone or Advanced Auto or Pep Boys etc...and they can read your codes for free...many times they may reset the light for you (sometimes not). But at least you'll know which area (or sensor) is throwing the fault code.

In the chart below...you can see the various FTP (federal test protocols) that occur at different stages...all test may not be conducted during a drive...as you can see in the chart below:



The SES (service engine soon) and/or CEL (check engine light) illuminate for the same reason..engine electronic emissions. You can see which areas of your engine's management system that OBD II covers...it is a sensor in one of these areas that has registered a fault...which is the reason your SES light illuminated.


(take note of the 3rd & 4th bullet in the image below)
