Models: DY41, DY42
In certain conditions, such as high humidity, salty air, etc, the oil sensor solenoid on the DY41 & DY42 can become stuck and fails to operate. This usually happens over a period of time.
Note: At the time of manufacture the solenoid is lubricated and should always be checked as part of regular servicing (ie. make sure the engine turns off at key) of the engine.
