Crankshaft Position Sensor (CKP) > FORD FIESTA & ECOSPORT & FOCUS 1.4L / 1.5L / 1.6L Duratec TI-VCT GASOLINE ENGINE > YS6A-6C-315AB | GENUINE PART (Ford Original Equipment)

This is a Genuine OEM Crankshaft Position Sensor (CKP Sensor), identified by the Ford part number YS6A-6C-315AB. This sensor is a factory-original component designed for the popular Duratec TI-VCT (Twin Independent Variable Camshaft Timing) Gasoline engine family used extensively in smaller Ford models like the Fiesta and Ecosport across various global markets.

The CKP sensor is a critical part of the engine management system:

Engine Timing Foundation: The sensor monitors the rotation of the crankshaft's reluctor wheel, supplying the ECM with the high-resolution data needed for engine speed and piston position.
VVT Synchronization: In TI-VCT engines, this timing data is vital for the ECM to correctly synchronize the crankshaft position with the camshaft position, allowing the Variable Valve Timing system to operate effectively for optimized power and fuel efficiency.
Genuine Quality: Installing a Genuine Ford Part ensures the sensor's signal output meets the strict tolerances required by the ECM, preventing common timing errors or difficult-to-diagnose intermittent issues associated with faulty sensors (like codes P0335 or rough idling).
Fitment Assurance: The part number YS6A-6C-315AB is consistently verified as the correct genuine CKP sensor for the 1.4L, 1.5L, and 1.6L Duratec TI-VCT Gasoline engine variants in the Ford Fiesta and Ecosport models you listed.
