How to reset service engine soon light

Put the key into the ignition and turn it to "Run." Don't start the engine. Press down slowly and fully on the gas pedal, then release it. Do this three times in five seconds. Watch for the "Service Engine Soon" light to start blinking. This indicates that the system is resetting itself. Turn the ignition to "Off" and wait one minute. Start the engine. The Service Engine Soon light will flash for a moment, then turn off. If it doesn't do this, repeat the process.
