A camshaft sensor is designed to last for a long time, often mirroring the lifespan of the vehicle itself. Under normal conditions, a camshaft sensor can easily last between 75,000 to 100,000 miles, if not longer. However, the actual longevity of the sensor can vary based on several factors, including the quality of the sensor itself, the driving conditions it’s exposed to, and how well the vehicle is maintained. While these sensors are built to be durable, external factors like oil leaks, extreme temperatures, or contaminants can affect their lifespan.
