Crank Shaft Position Sensor (CKPS) is magnetic inductive type. Mounted on cylinder block, it senses tone wheel position of crank shaft. As tone wheel is divided with 58 teeth and 2 missing teeth (reference point), 1 tooth corresponds to 6 degree. CKPS which calculates RPM and crank angle is important to determine fuel injection quantity and injection timing with APS. Crank shaft position is closely related to engine starting.
P0336 is set corresponding to the condition of ECM internal counter when 1). engine speed detected by CKPS is above 6000RPM, or 2). CKPS signal pulse is abnormal. For repair, check temporary poor connection in CKPS circuit, component failure or deformation of tone wheel.
