The correct way would be to hook it up to a scanner and reset it. You can also disconnect the battery for ten or fifteen minutes. It will come back on until the problem has been fixed (gas cap replaced or evap leak repaired).

How can I reset the service engine soon light on a 2000 Oldsmobile Intrigue


Hi,
The service light is indicating there is a fault code either in the ECM or BCM system. The only way in which this can be switched off is to have these codes checked and cleared in these to control unit with a diagnostic tool.

Check engine light came on. Code P1456.


Did you change the gas cap with a Honda gas cap? Tighten it at least three clicks?
Also, Honda recommends that you never top off the tank when getting gas (only go to the click-off of the pump; otherwise you can get back flow into the system that will cause the code).
Tightening or replacing the cap will not immediately cause the light to go off; it can take up to three days of driving for the light to reset.
To check if your readiness codes (emission system) are set, turn the ignition to ON (II), without starting the engine. The Malfunction Indicator Lamp will come on for 20 seconds. If it then goes off, the readiness codes are set. If it blinks 5 times, the readiness codes are not set.
You can, of course, try resetting your engine light to see if it will come back on (which it probably will). I believe the procedure is:
Turn off the engine.
Press and hold the Select/Reset knob (odometer) in the instrument panel, then turn the ignition switch to ON (II).
Hold the knob for approximately ten seconds until the indicator resets.

Hope this helps you.

Check engine light went on


More than likely, it is the factory preset service interval indicator. You can usually take the car to a parts store that does electrical testing and they will tell you if it is a legitimate trouble code or just reset the service indicator for you.
