Airtex 5S11521 Engine Crankshaft Position Sensor CKP Sensor

The Airtex 5S11521 Engine Crankshaft Position Sensor (also called a crank sensor, CKP sensor or crankshaft speed sensor) is a replacement part for the engine management system. It monitors crankshaft position and rotational speed. It sends that signal to the engine computer, which uses it to set ignition timing and fuel delivery and to detect engine RPM.

Key Features:

• Validation tested from -40 to 300 degrees Fahrenheit
• Life-cycle tested to meet or exceed OE specifications
• Designed to restore accurate timing signals and consistent engine performance
• OE-style design for straightforward installation

A failing crankshaft position sensor can cause a check engine light, rough running, stalling or a no-start condition. Replacing it with a quality sensor helps restore reliable starting and smooth engine operation.
