Check what code is causing the light to come on, and that will correspond to a fault. If you press off and warmer on your climate panel, it will display 'E' codes in the fuel data center. Record the codes and report back. If you changed your map sensor, check to make sure the vacuum line is good or connected to it as well as the connector. Pull the fuse for the ecm for 30 seconds then reinstall. Start the vehicle up and see if the light comes back on. If it does have a pro take a look at it as it may have a bad connection.
