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

Question

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

Answer 1

Both A and BExplanation:- Technician A is correct in stating that a faulty Crankshaft Position Sensor (CKP) can prevent the engine from starting because the Engine Control Module (ECM) won't receive crankshaft position data to trigger spark and fuel injection.- Technician B is also correct in stating that if the Camshaft Position Sensor (CMP) fails, the engine may still start but could experience extended cranking, rough idle, or improper fuel injection timing.Therefore, both Technician A B are correct.
