Component Location Overview
In this video, I provide a clear and direct look at the location of the Crankshaft Position (CKP) sensor for the 2015–2018 Lincoln MKC with the 2.0L EcoBoost engine. On this turbocharged engine, the CKP sensor is located low on the engine block, typically near the timing cover/crankshaft pulley area. It is designed to read the reluctor wheel on the crankshaft to determine engine speed and piston position. This visual guide will help you identify the sensor housing and the electrical connector, which are critical for an efficient, error-free replacement.
Benefits for DIY Repairs
The CKP sensor is fundamental to your engine’s management system. If it fails, the Engine Control Module (ECM) cannot determine the timing required to fire the spark plugs or inject fuel, leading to an immediate “no-start” condition or sudden stalling while driving. Replacing this sensor yourself is a very high-value DIY task; it is inexpensive and simple, but shops often charge significant diagnostic fees to locate and replace this specific part. Using this guide allows you to bypass the dealership experience and get your MKC back on the road confidently.
Common Symptoms of Failure
If your Lincoln is struggling with a faulty crankshaft position sensor, keep an eye out for these symptoms:
- Engine Cranks but Won’t Start: This is the most definitive sign. The starter motor turns the engine over, but there is no spark or fuel delivery to allow it to run.
- Sudden Stalling: The engine may shut off abruptly while driving, often without warning, and may restart only after it has cooled down.
- Erratic Tachometer: You may notice the RPM gauge on your instrument cluster jumping sporadically or remaining at zero while you are cranking the engine.
- Check Engine Light: You will almost certainly have diagnostic trouble codes (DTCs) related to the crankshaft position sensor circuit, such as P0335 or P0336.
Safety Precautions
Because you are working in the lower engine bay, safety is paramount:
- Disconnect the Battery: Mandatory. Always disconnect the negative (-) battery terminal before beginning. You do not want the engine to attempt a start while your hands are working near the spinning components or sensitive electrical sensors.
- Secure Vehicle Support: Because the sensor is located low on the block, you will likely need to work through the wheel well or from underneath the vehicle. Always use rated jack stands. Never trust a floor jack alone.
- Cleanliness is Key: Before you unbolt the old sensor, use a brush or compressed air to clean the area around the base. You must prevent dirt, road grit, or oil from falling into the sensor port on the engine block, as this can interfere with the new sensor’s ability to read the reluctor wheel.
- Protective Gear: Wear safety glasses to keep debris from falling into your eyes, and use work gloves to protect your hands from sharp metal edges under the vehicle.
