• Monitors and adjusts the position and rotation of the camshaft
• A failing sensor will likely trigger the check engine light
• Replace at the first sign of failing to avoid additional or long-term damage

Your Nissan's Engine Camshaft Position Sensor is responsible for monitoring and helping adjust the position and rotation of the camshaft — an engine rod that controls engine valve movement and helps with the critical ignition function in your Nissan. The Engine Camshaft Position Sensor on your vehicle helps the camshaft rotate correctly to ensure your engine provides optimal fuel efficiency.

The Engine Camshaft Position Sensor helps give the right amount of spark and fuel to the engine by determining which cylinders are in their power stroke — when the pistons are pushed down by the fuel and air mixture combustion.

Your Nissan's Engine Camshaft Position Sensor is crucial to the operation of the engine. A malfunctioning Engine Camshaft Position Sensor might cause several symptoms, including an illuminated check engine light, transmission issues when the vehicle is shifting gears, decreased driving performance, a difference in fuel economy, and an engine knocking sound due to inaccurate fuel ratios in the engine.

A failing Engine Camshaft Position Sensor should be replaced right away to avoid further issues. Purchase a genuine OEM replacement Engine Camshaft Position Sensor custom-designed for your vehicle. Plus, every genuine Nissan Part includes a 12-month/12,000-mile warranty (whichever comes first) so you can feel confident you're receiving a quality product.
