The Genuine 237311CA0B is an OEM crankshaft position sensor designed for select Nissan and Infiniti vehicles equipped with VK50VE and VK56VD engines. This factory-direct sensor monitors the rotational position and speed of the crankshaft, providing critical data to the Engine Control Unit (ECU) for precise ignition timing and fuel injection control.

Key Features:

• Genuine OEM part manufactured to factory specifications
• Monitors crankshaft position and rotational speed in real-time
• Essential for proper engine timing and performance
• Direct replacement for part numbers 23731-1CA0A and 237311CA0B

The crankshaft position sensor is one of the most important sensors in modern engine management systems. It works by detecting the rotation of a reluctor ring or toothed wheel attached to the crankshaft, generating electrical signals that the ECU uses to calculate engine RPM and determine optimal spark and fuel injection timing. Without a functioning crankshaft position sensor, the engine will not start or may cut out while running.

This sensor replaces superseded part number 23731-1CA0A and is designed for precise fitment and reliable operation in your vehicle's demanding engine environment.
