The motor is a 02 496 ho. The alarm is going off at any time. The problem was traced to the exhaust sensor,that was replaced still have the same problem. Went further to a pin in the wiring harness and it was ok for almost 2 weeks now it started again. Hooked the computer back up and it still says it is the sensor. Any ideas or if there are any recalls? On these motors evan if you unplug the sensor it still won't stop!! Thanx...
