Common Symptoms of a Faulty Crankshaft:

A malfunctioning crankshaft can significantly affect engine performance. The most common symptoms include:

1. Illuminated Check Engine Light:
   A defective crankshaft sensor may activate the check engine light, indicating that the engine control module has detected issues with the crankshaft’s position or speed readings.
2. Decreased Fuel Efficiency:
   A faulty crankshaft can cause inefficient fuel combustion, forcing the engine to work harder and consume more fuel, leading to reduced gas mileage.
3. Engine Stalling:
   The crankshaft sensor provides crucial timing information. If it malfunctions, the engine might lose synchronization, causing unexpected stalling during operation.
4. Excessive Engine Vibrations:
   A damaged or unbalanced crankshaft disrupts the engine’s smooth rotation, leading to noticeable vibrations, particularly when idling or at low RPMs.
5. Engine Misfires:
   Incorrect data from the crankshaft sensor can lead to improper ignition timing or fuel injection, resulting in misfires and diminished performance.
6. Sluggish Acceleration:
   When the crankshaft sensor fails to transmit accurate signals, the engine may struggle to respond to acceleration demands, resulting in poor performance.
7. Low Oil Pressure:
   A malfunctioning crankshaft can disrupt the engine’s oil flow, reducing oil pressure and potentially leading to severe engine damage if unresolved.
