• 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 is responsible for monitoring and helping adjust the camshaft's position and rotation — 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 correctly to ensure 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 piston is being pushed down by the combusting fuel and air mixture.

The Engine Camshaft Position Sensor is crucial to engine operation. 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, changes in fuel economy, and a knocking sound in the engine due to improper ratios of fuel in the engine.

A faulty or malfunctioning Engine Camshaft Position Sensor should be replaced immediately to help avoid any further issues.
