A Guide to the Engine Oil Pressure Switch for the 2015-2019 Lincoln MKC
Learn the symptoms of a bad oil pressure sensor and how to choose the right replacement for your Lincoln MKC.
- A flickering or constant oil light is the primary symptom; check for code P0520 if the Check Engine Light is also on.
- For reliability, using the OEM Motorcraft brand is highly recommended by owners and mechanics.
- Never ignore an oil pressure warning, as it could be signaling a real condition that can destroy your engine.
- Check if the critical NHTSA recall #23V-378 for a potential fire risk has been performed on your vehicle.
Is Your Lincoln MKC Oil Pressure Light On?
A warning light on your dashboard can be stressful. If it's the oil pressure light in your 2015-2019 Lincoln MKC, you need to pay attention. The problem could be as simple as a faulty sensor, or it could be a sign of a serious engine issue. This guide will help you understand the symptoms, choose the right replacement part, and decide if this is a repair you can handle yourself.
Important Safety Recall Information (NHTSA #23V-378)
All 2015-2019 Lincoln MKC models are under a safety recall for an issue unrelated to the oil pressure switch. The battery monitor sensor can short-circuit and cause an engine compartment fire, even when the vehicle is parked and turned off. The fix involves a dealer installing a fuse for the sensor circuit. It is strongly recommended that you contact a Lincoln dealer to ensure this free recall service has been performed on your vehicle.
Symptoms of a Failing Oil Pressure Switch
When an oil pressure switch goes bad, it can give false signals. Here are the most common signs:
- Oil Pressure Light On: The light may flicker, stay on constantly, or come on and off randomly. This is the most common symptom.
- Check Engine Light: A faulty switch can trigger the check engine light, often storing the diagnostic trouble code P0520 (Engine Oil Pressure Sensor/Switch Circuit).
- Incorrect Gauge Reading: If your MKC has a digital oil pressure gauge, it might read zero, show an unusually high reading, or jump around erratically.
- Oil Leaks: The switch itself can fail and leak oil. You might see oily residue on the sensor or drips under the engine. 🎬 See more warning signs of a failing oil pressure sensor here.
Choosing the Right Aftermarket Switch for Your MKC
When replacing this sensor, you have a few options. For electronic parts, quality and reliability are key to avoiding future problems.
Tier 1: OEM (Motorcraft)
Motorcraft is the original parts supplier for Lincoln. Choosing a Motorcraft switch ensures perfect compatibility and the highest reliability. Many professional mechanics and owners recommend sticking with the OEM part for critical sensors to avoid issues like premature failure or inaccurate readings that are sometimes seen with cheaper alternatives.
Tier 2: Premium Aftermarket (Hella, Standard Ignition)
Brands like Hella and Standard Ignition are reputable aftermarket manufacturers. They design their parts to meet or exceed original equipment standards and perform extensive testing. These are solid choices if you are looking for a high-quality part that may be more readily available or slightly less expensive than the OEM option.
Tier 3: Budget-Friendly (True Tech)
Budget brands offer a low-cost alternative. While functional, they may not have the same long-term durability or precise calibration as premium brands. A budget part can be a solution if cost is the primary concern, but be aware of the trade-off in potential lifespan and performance.
Pro Tip: Check for Leaks
Some Ford vehicles with similar EcoBoost engines have had issues with oil leaking from the sensor's threads, not from the sensor itself. When replacing your switch, make sure the engine surface is clean. If your new switch does not have thread sealant pre-applied, use a small amount of appropriate sealant on the threads to ensure a leak-free installation.

Frequently Asked Questions
Can I replace the oil pressure switch myself?
Yes, this is a manageable DIY job for someone with basic tools. The switch is located on the bottom of the engine, near the oil filter. You will need to safely raise the vehicle, disconnect the wire, and use a deep socket (like a 21mm) to unscrew the old sensor. Be prepared for a small amount of oil to spill.
🎬 Follow this guide to replace the switch using basic hand tools.What does the code P0520 mean?
P0520 is a generic diagnostic trouble code that means the vehicle's computer has detected a problem with the engine oil pressure sensor or its circuit. This could be a bad sensor, a wiring issue, or an actual oil pressure problem. A faulty sensor is a very common cause for this code.
Where is the oil pressure switch located on the 2015-2019 Lincoln MKC?
For the 2.0L and 2.3L EcoBoost engines used in the MKC, the oil pressure switch is located on the front, lower, passenger side of the engine block. It is typically found near the oil filter housing and may be underneath the starter motor.

Ignoring the issue is risky. If the switch is faulty and giving false warnings, it's an annoyance. But if the switch has failed and can no longer warn you of a *real* low oil pressure problem, you could suffer catastrophic engine failure without any warning. It is always best to diagnose the problem promptly.
