Exhaust System Noise

Noise from the exhaust system should never be ignored, as this can indicate a problem with the vehicle. Some of the most common sources include a damaged muffler or exhaust pipe. To identify the noise, start the engine and listen for any unusual sounds.

Decreased Fuel Efficiency

If the sensor is damaged or malfunctioning, it can send incorrect motions to the engine, leading to increased fuel consumption.
