The Engine Camshaft Position Sensor in your INFINITI monitors and adjusts the position and rotation of the camshaft — an engine rod that controls engine valve movement and directly assists in the essential ignition function of your INFINITI. The Engine Camshaft Position Sensor helps the camshaft rotate properly to make sure your engine has optimal fuel efficiency.

The Engine Camshaft Position Sensor helps give the right amount of spark and fuel to the engine by assessing which cylinders are in their power stroke — when the piston is being pushed down by the combusting fuel and air mixture.

Your INFINITI Engine Camshaft Position Sensor is an essential component in your vehicle's engine operation. A failing Engine Camshaft Position Sensor could result in several noticeable symptoms, including an illuminated check engine light, transmission issues when shifting, a decrease in driving performance, changes in fuel economy, or a knocking sound in the engine due to inaccurate fuel ratios in the engine.

To help avoid further issues, a malfunctioning Engine Camshaft Position Sensor should be replaced as soon as possible. Shop for a replacement OEM Engine Camshaft Position Sensor designed to fit your INFINITI. Additionally, every part purchased from INFINITI Parts comes with a 12,000-mile/12-month warranty, whichever comes first, so you can know you're getting a quality product.
