I have a 03 DT 150 that is sounding the alarm for two seconds straight and flashing the rev limit light every ten min. or so at idle. Any ideas whats causing this. Its not storing codes or anything. How would one go about finding what sensor is causing this unplugging each one until it stops? Its running around 160 degrees. Would appreciate any ideas. Thanks...
