Component Location Overview
In this video, I provide a clear and direct look at the location of the Crankshaft Position (CKP) sensor for the 2012–2016 Lincoln MKZ 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 responsible for reading the reluctor wheel on the crankshaft to provide the engine computer with precise data on engine speed and piston position. This guide will help you identify the sensor housing and the electrical connector, ensuring you can navigate the tight confines of the lower engine bay without confusion.
Benefits for DIY Repairs
The CKP sensor is one of the most critical components in 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, resulting in an immediate “no-start” condition or sudden stalling while driving. Replacing this sensor yourself is a high-value DIY task: it is inexpensive and physically simple, yet repair shops often charge significant fees for diagnostic time. Using this guide allows you to skip the shop and get your MKZ back on the road with confidence.
Common Symptoms of Failure
If your Lincoln is struggling with a faulty crankshaft position sensor, watch for these common indicators:
- Engine Cranks but Won’t Start: This is the most common symptom—the starter motor spins the engine, but there is no spark or fuel delivery, preventing the car from running.
- Sudden Stalling: The engine may shut off abruptly while driving, often without warning, and might only restart once the engine has cooled down.
- Erratic Tachometer: You may notice your RPM gauge on the instrument cluster jumping sporadically or remaining at zero while you are cranking the engine.
- Check Engine Light: You will almost certainly trigger diagnostic trouble codes (DTCs) related to the crankshaft position sensor circuit, such as P0335 or P0336.
Safety Precautions
Working in the lower engine bay requires prioritizing safety:
- Disconnect the Battery: Mandatory. Always disconnect the negative (-) battery terminal before beginning. You never want the engine to attempt to crank while your hands are working near the spinning components or sensitive electrical sensors.
- Secure Vehicle Support: Because the sensor is located low on the engine 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 while under the car.
- Maintain Cleanliness: Before you unbolt the old sensor, use a brush or compressed air to clear the area around the base. It is critical to 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 crankshaft reluctor wheel.
- Protective Gear: Wear safety glasses to protect your eyes from falling debris, and use work gloves to protect your hands from sharp metal edges under the vehicle.
