2 ways
\015\012the only way to clear it immediately is to take it someplace that has a scanner to clear codes
\015\012the other way is-
\015\012the CEL illuminates when the PCM(powertrain control module)recieves a faulty signal from a sensor. at this time it basically takes a picture(freeze frame data)of every sensor and every value the vehicle puts out. once these values are reached again, at the same moment the problem occured with no malfunction it records it. after severa drive cycles with no malfunction the CEL will shut off. the could may however still stay in the system as a history code-the light will not be on.
