A customer complains that their vehicle cranks but does not start. A scan tool reveals a P0335 (Crankshaft Position Sensor Circuit Malfunction) trouble code. Technician A says that a faulty CKP sensor can prevent the engine from starting because the ECM won't receive crankshaft position data to trigger spark and fuel injection Technician B says that if the CMP sensor fails, the engine may still start but could experience extended cranking ,rough idle, or improper fuel injection timing. Technician A Technician B Both A and B Neither A nor B
