Nissan Altima Crankshaft Position Sensor

The Crankshaft Position Sensor of the Nissan Altima sends information to the engine computer to allow the timing of fuel and ignition. The module makes use of an electronic sensor. This sensor is positioned close to the pulley, flywheel, camshaft, or the crankshaft itself. It sends electronic impulses that make it possible for the module to control several engine parameters. This helps the Nissan Altima engine start and run smoothly. An underperforming Crankshaft Position Sensor can lead to hard starting, stalling, poor idle, misfires, or hesitant acceleration. The Crankshaft Position Sensor has four main styles: the inductive style, Hall effect style, magnetoresistive style, and optical style. The crankshaft rotates passively in an inductive style to create its own signal. The Hall effect and magnetoresistive styles can read static magnetic fields. The optical style has very accurate edge detection but can be influenced by fouling. Each Crankshaft Position Sensor is sealed to prevent damage from heat, vibration, corrosion, and fluids found in the engine bay. The Crankshaft Position Sensor gives reliable data which helps keep the Nissan Altima powertrain synchronized and every Nissan Altima equipped system working properly.

All our parts are offered at unbeatable prices and are supported by the manufacturer's warranty. In addition, we offer quick shipping to have your parts delivered to your door step in a matter of days.
