When performing engine repair or maintenance on any Mitsubishi model, there is a chance that engine coolant or water may leak into the crank angle sensor, causing the engine to stall.

This may be due to coolant or water ingress into the crank angle sensor harness connector, resulting in an internal short circuit.

To prevent this, during service work, cover any exposed coolant connections and/or drain plug as well as covering the crank angle sensor connector.
