FAQS

What happens when a crankshaft sensor goes bad?

When a crankshaft sensor goes bad, it can lead to various issues with your vehicle's engine performance. You might experience problems such as difficulty starting the engine, rough idling, stalling, misfiring, and a noticeable decrease in fuel efficiency. These symptoms can significantly affect your driving experience and the overall health of your vehicle.

What does a crankshaft position sensor do?

A crankshaft position sensor is a crucial component of a vehicle's engine management system. It's responsible for monitoring the position and speed of the crankshaft, which helps the engine control unit (ECU) determine the ignition timing and fuel injection timing. In simpler terms, the crankshaft position sensor ensures that the engine operates smoothly by providing essential data for precise fuel delivery and ignition timing.
What are the 7 symptoms of a bad camshaft position sensor?

Here are seven symptoms that may indicate a bad camshaft position sensor:

Engine misfires or runs roughly: A faulty camshaft position sensor can cause erratic engine operation, leading to misfires and rough idling.

Difficulty starting the engine: A bad camshaft position sensor can make it challenging to start the engine, especially when cold.

Decreased fuel efficiency: If the sensor is malfunctioning, it can affect the engine's fuel delivery, resulting in lower fuel efficiency.

Engine stalling: A failing camshaft position sensor may cause the engine to stall unexpectedly, especially during acceleration or at idle.

Illuminated check engine light: A malfunctioning camshaft position sensor can trigger the check engine light on your dashboard.

Loss of power or hesitation: You may notice a lack of power or hesitation during acceleration, indicating a potential issue with the sensor.

Rough engine performance: The engine may run roughly or exhibit vibration due to irregular camshaft position readings.

How do I know if my crankshaft is bad?

​Determining if your crankshaft is bad requires a thorough inspection by a qualified mechanic. However, several signs could indicate a problematic crankshaft:

Loud knocking or banging noises from the engine: This could indicate worn-out bearings or a damaged crankshaft.
Engine vibration or shaking: A faulty crankshaft can cause vibrations that are felt throughout the vehicle.
Oil leaks: A damaged crankshaft can lead to oil leaks, which may be visible under the engine or near the crankshaft area.
Engine performance issues: If your engine experiences power loss, rough idling, or struggles to maintain consistent RPMs, it could be due to a bad crankshaft.
