Re: How do you reset the "check engine" light?
in the fuse box under the dash you will see a fure spot thats a little lower than the rest of the fuse spots, its toward the front of the car. with fuse in and key on will blink out codes. error code 31 is MAP sensor, located on firewall by the wiper motor. make sure hose going to it is good and not plugged or cracked, plug and unplug the wire a couple times. unhook battery for at least a minute. pull the fuse out of the fuse box, hook pattery up and start car. if check engine light is out and stays out your fine, if it come back on and you get code 31 again your map sensor is bad
