2020-2023 Lincoln Aviator Engine Oil Pressure Switch: A Complete Guide
Is your oil light on? Here’s what every 2020-2023 Lincoln Aviator owner needs to know about the engine oil pressure switch.
- The second-generation Lincoln Aviator covers model years 2020-2023, not 2017-2019.
- A low oil pressure warning can be caused by a simple faulty sensor, but it must be diagnosed properly to rule out serious internal engine issues mentioned in TSB SSM 51764.
- Do not drive if the oil pressure light is on, as it could signal a true low-pressure condition that can destroy your engine.
- Standard Ignition (SMP) is a reputable aftermarket brand that offers a cost-effective and reliable replacement for the OEM sensor.
Understanding the Oil Pressure Light in Your Aviator
Seeing the red oil pressure light turn on in your 2020-2023 Lincoln Aviator can be alarming. While it can indicate a serious problem like low oil level or a failing oil pump, it often points to a much simpler issue: a faulty engine oil pressure switch. This sensor is a common failure point that can send false signals, causing the light to come on even when the oil pressure is perfectly fine. Before assuming the worst, it's important to understand the symptoms and what to do next.
Symptoms of a Failing Engine Oil Pressure Switch
A bad oil pressure switch can show several signs. You might see the oil pressure warning light flickering or staying on constantly. In some cases, the oil pressure gauge on your instrument panel might give erratic readings, jumping from high to low, or showing zero pressure. You may also notice a small oil leak from the sensor itself. If you see any of these symptoms, the first step is always to check your engine oil level to rule out a true low-oil situation.
TSB for Low Oil Pressure Warnings
Ford has issued Technical Service Bulletin (TSB) SSM 51764 for some 2020-2023 Aviator models with the 3.0L EcoBoost engine that show a low oil pressure warning and have diagnostic trouble codes P0521 or P0524. This TSB notes that the cause could be an internal oil pressure leak, which is a more serious issue than a faulty sensor. It is critical to have a professional diagnose the problem to determine if the issue is the sensor or a more significant internal engine problem.
Choosing an Aftermarket Replacement: Standard Ignition
When it's time to replace the switch, you have options. While the original equipment (OEM) part from Lincoln is available, a quality aftermarket part can offer reliable performance at a better price. For the 2020-2023 Aviator, Standard Ignition (also known as Standard Motor Products or SMP) is a widely available aftermarket brand.
Standard Motor Products has been a long-standing name in the aftermarket and is generally considered a quality brand that often supplies parts that meet or exceed original specifications. Many users have had positive experiences with SMP parts, finding them to be reliable and a good value compared to more expensive dealer parts. For a simple but critical sensor like the oil pressure switch, a Standard Ignition replacement is a solid choice for your Aviator.
Pro Tip: Check for Leaks
When replacing the sensor, it's a good time to inspect the area for any oil residue. A leaking switch is a clear sign of failure. Ensure the new sensor is threaded correctly and tightened to the proper specification to prevent leaks. Some new sensors come with thread sealant already applied.
Cost to Replace an Engine Oil Pressure Switch
The cost of replacing the oil pressure switch is relatively low, especially if you do the work yourself. The main cost is the part itself, with labor being a smaller factor due to the easy accessibility of the sensor on the 3.0L engine.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Part (Standard Ignition) | $30 - $50 |
| Shop Labor | $91 - $134 |
| Total Estimated Cost (Aftermarket) | $121 - $184 |
Frequently Asked Questions (FAQ)
Where is the oil pressure switch located on a 2020-2023 Lincoln Aviator?

Can I drive my Aviator with a bad oil pressure switch?
It is not recommended. The switch's job is to warn you of low oil pressure, which can cause catastrophic engine damage. If the light is on, you cannot be sure if it's a faulty sensor or a real, engine-destroying pressure problem. You should stop driving, check your oil level, and have the vehicle diagnosed immediately.
Is replacing the oil pressure switch a DIY job?
Yes, for someone with basic mechanical skills, this is a feasible DIY repair. 🎬 Watch a similar oil pressure switch replacement on a Ford engine. It involves safely raising the vehicle, unplugging the electrical connector, and using a socket or wrench to unscrew the old sensor and install the new one. The job typically takes less than an hour.
Are there any recalls for the oil pressure switch on the Lincoln Aviator?
No, there are no specific recalls for the engine oil pressure switch itself. However, TSB SSM 51764 was issued for low oil pressure warnings, which could be related to the sensor or more serious internal leaks. There have been other unrelated recalls for the Aviator.
