What are the symptoms of a crankshaft sensor going out?


The symptoms of a failing or faulty crankshaft sensor can vary depending on the severity of the problem, but here are some common signs to look out for:

1. Engine stalling or hesitation: A malfunctioning crankshaft sensor can cause the engine to stall or hesitate during acceleration due to a lack of accurate timing information being sent to the engine control module (ECM).

2. Difficulty starting the engine: If the crankshaft sensor is failing, it may prevent the engine from starting or make it difficult to start, since the ECM won't be receiving accurate information about the engine's position and timing.

3. Rough idling: A faulty crankshaft sensor can cause the engine to run rough or have an uneven idle due to the incorrect timing of fuel and air delivery to the cylinders.

4. Check engine light: A failing crankshaft sensor can trigger the check engine light to come on, indicating a problem with the engine's sensors or control system.

5. Decreased fuel economy: If the crankshaft sensor is failing, it may cause the engine to run inefficiently, which can result in decreased fuel economy.

If you experience any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic to diagnose the problem and make any necessary repairs. Ignoring a faulty crankshaft sensor can lead to more significant engine problems and potentially leave you stranded on the road.
