Crankshaft Sensor Symptoms: Diagnosis & Replacement

Quick Answer: Bad crankshaft position sensor (CPS) = one of 7 signs: (1) check engine light (codes P0335, P0336), (2) engine won’t start (no signal = no fuel/spark), (3) rough idling (misfires from timing issues), (4) stalling while driving (intermittent signal dropout), (5) poor acceleration (ECU can’t calculate timing), (6) ticking/knocking (timing way

can a bad tensioner cause loss of power

Bad Tensioner Loss of Power: Symptoms & Diagnosis

Quick Answer: Bad tensioner = one of 7 signs: (1) squealing noise (belt slipping on pulley), (2) visible pulley wobble (bearing failure), (3) rough idling (belt tension unstable), (4) poor acceleration (2-5 hp loss from drag), (5) belt fraying (loose belt whipping), (6) alternator dimming lights (belt slip reduces charging), (7) engine vibration (loose belt
