Engine oil inside the sensor wiring connector could cause expansion due to the heat of the engine and could deform the sensor wiring connector. The connector may become disconnected, which could cause the engine to stall while driving and not be able to be restarted increasing the risk of a crash.
On certain passenger vehicles, due to improper molding of the resin body of the crankshaft position senor installed on the engine block, engine oil may penetrate the seal and enter the sensor wiring connector. The wire harness connector may not be sufficiently attached to the locking tab of the sensor wiring connector.
