Crankshaft Position Sensor Ford Focus 2.0L 2011-2018 Location and Replacement

In this video, you will see the process of locating and replacing the Crankshaft Position (CKP) Sensor on a Ford Focus 2.0L engine. If your car is cranking over but refuses to start, stalls out completely once the engine warms up, or is throwing a timing pulse code, this visual guide shows you exactly where to look on the engine to find the sensor and how to swap it out.

How this video helps you: The crankshaft position sensor is positioned at the bottom of the engine assembly to read the teeth on the crankshaft pulse wheel. Because it is hidden down in a dark, tight workspace near the engine oil pan, drive pulley, and lower structural frames, it is completely impossible to see from the top of the engine bay. This video points directly to its exact location on the vehicle so you can see it clearly from the proper angle underneath. You will see how to safely disconnect the locking electrical wiring connector, how to clear enough working room, and how to unbolt the sensor cleanly.

Common symptoms of a bad Crankshaft Position Sensor: The CKP sensor calculates the exact speed and position of the crankshaft, passing this vital signal to the computer so it knows exactly when to fire the spark plugs and inject fuel. If this sensor fails or drops its signal, the computer shuts down the engine instantly to prevent timing damage, causing these issues:

• Engine Cranks but Won’t Start: The starter motor turns the engine over perfectly fine, but the car completely refuses to fire up and run because the computer has cut off spark and fuel delivery without a valid RPM signal.
• Sudden Stalling When Warm: The car drives perfectly fine for the first 15 to 20 minutes, but as soon as the engine bay reaches full operating temperature, the car dies instantly (as if someone pulled the plug). Often, it will refuse to restart until the sensor body cools down for an hour.
• Check Engine Light & CKP Codes: Circuit failures or missing timing pulses will instantly trigger the light, storing trouble codes like P0335, P0336, or P0339.
• Severe Engine Misfires & Shaking: If the sensor signal is weak or erratic, the engine will experience random misfires, bucking, or violent shaking during acceleration.
