• 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 INFINITI Engine Camshaft Position Sensor monitors and helps adjust the position and rotation of the camshaft — a rod in your engine in charge of controlling engine valve movement which helps with the critical ignition function. The Engine Camshaft Position Sensor on your vehicle helps the camshaft rotate correctly to make sure your engine has optimal fuel efficiency.

The Engine Camshaft Position Sensor helps send the correct amount of fuel and spark to the engine by assessing which cylinders are in their power stroke — when the combusting fuel and air push the piston down.

Your INFINITI Engine Camshaft Position Sensor is crucial to the operation of the engine. A failing Engine Camshaft Position Sensor could result in several noticeable symptoms, like a check engine light that's illuminated, transmission issues when the vehicle is shifting gears, decreased driving performance, a decrease in fuel economy, and a knocking sound coming from the engine due to incorrect ratios of fuel in the engine.

A faulty or malfunctioning Engine Camshaft Position Sensor should be replaced immediately to help avoid any further issues. Shop for a replacement OEM Engine Camshaft Position Sensor designed to fit your vehicle. In addition, you'll get a 12-month/12,000-mile warranty, whichever occurs first, when you purchase your replacement part from INFINITI Parts so you can know you're getting a quality product.
