Engine Cuts Out 900

Hi Brian,

The most likely culprit I can think of is the crank sensor

The most likely scenario for THIS intermittent shut down but able to restart immediately after was a speedbump or undulation on the road where the engine did shake a lot

Reason: The crank sensor's wiring has a hairline break (referring not to the plastic insulation but the inside electrical wire itself)

Remedy: Replace the sensor

OBD code: May be there or not be there. Intermittent fault rarely triggers OBD code

Experiment/Test: Try driving the car over any large speedbump and symptom recur. Or a better one, take out the crank sensor (the 900 series has ample hand space for this) connect to multimeter in continuity mode and shake it

Why did I suspect that: Had experienced this before


Hope that helps,
Amarin
