• 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

The Engine Camshaft Position Sensor in your INFINITI monitors and adjusts the position and rotation of the camshaft — a rod in your engine that controls engine valve movement and helps with the critical ignition function. The Engine Camshaft Position Sensor helps the camshaft rotate correctly to ensure your engine gets the best fuel efficiency.

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

The Engine Camshaft Position Sensor on your INFINITI 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, and a knocking sound in the engine due to improper ratios of fuel.

A failing Engine Camshaft Position Sensor should be replaced right away to help avoid 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.
