Lexus LC500 (2018-2024) Engine Oil Pressure Switch: A Complete Guide
Don't let a simple switch cause major engine anxiety; know the signs and how to choose the right replacement.
- If the oil light comes on, always check the oil level first before assuming the switch is bad.
- There are no known common issues or recalls for this specific part on the LC500, so failure is not expected.
- Choosing a premium aftermarket brand like Beck Arnley or a quality brand like Standard Ignition is a reliable, cost-effective repair.
- The replacement is simple and low-cost, making it a wise preventative repair if you suspect a failure.
Is Your Oil Pressure Light On? What It Means for Your LC500
Seeing the red oil can symbol light up on your LC500's dashboard can be alarming. The cause could be two very different things: a simple, inexpensive failed switch, or a serious, engine-threatening loss of oil pressure. The first step is always to stop the car safely, turn off the engine, and check the oil level using the dipstick. If the oil level is correct, the problem is very likely a faulty oil pressure switch.
Symptoms of a Failing Oil Pressure Switch
- Oil Pressure Light Stays On: The most common symptom is the oil pressure warning light illuminating on the dash, even when the engine oil level is full.
- Flickering Oil Light: The light may flicker intermittently, especially at idle or during turns, as the switch begins to fail and sends inconsistent signals.
- Incorrect Gauge Reading: If your vehicle has a pressure gauge, it might read zero or fluctuate wildly, which is a strong sign of a bad sensor if the oil level is normal.
- Visible Oil Leak: The switch itself can fail and leak oil. If you notice a small oil drip from the area around the sensor, it needs to be replaced.
Warning: Do Not Ignore the Oil Pressure Light
Never assume the warning light is just a bad switch. Always verify your engine's oil level immediately. Driving with low oil pressure can cause catastrophic engine damage in a very short amount of time.
Choosing the Right Aftermarket Oil Pressure Switch
For the 2018-2024 Lexus LC500, there are no widespread recalls or service bulletins for premature oil pressure switch failure, suggesting the original part is reliable. However, when a replacement is needed, you have a choice between OEM and several aftermarket brands. For a simple but critical part like this, quality matters.
Aftermarket Brand Tiers for Your Lexus
Not all aftermarket parts are created equal. Here’s a breakdown of the available brands based on general reputation:
- Premium Aftermarket (OEM-Equivalent): Brands like Beck Arnley are often considered top-tier. They are known for sourcing parts from original equipment manufacturers and re-boxing them, giving you OEM quality without the dealer price tag.
- Quality Aftermarket: Brands such as Standard Ignition (SMP) and Holstein are reputable manufacturers with a history of producing reliable sensors. Standard manufactures many of its parts in North America, and Holstein promotes a low failure rate and a strong warranty. These are solid choices for a reliable repair.
- Standard/Budget Tier: Brands like Facet, Global Parts, and True Tech may offer a lower price point. While they can be functional, for a critical sensor on a high-performance engine like the LC500's, sticking with a more established, reputable brand is a safer investment.
Pro Tip: OEM vs. Aftermarket
Because this part is not a common failure point on the LC500, a high-quality aftermarket switch from a brand like Beck Arnley or Standard Ignition is a perfectly acceptable and cost-effective alternative to an OEM part from a Lexus dealership.

Frequently Asked Questions
Where is the oil pressure switch located on the 2018-2024 Lexus LC500?
The oil pressure switch on the 2UR-GSE engine is located on the front of the engine block, down low near the crankshaft pulley and oil filter assembly. A technician will typically access it from under the vehicle by removing the engine splash shield.
Can I replace the oil pressure switch myself?
Yes, this is a DIY-feasible job for someone with basic mechanical skills and tools. You will need to safely lift the vehicle, remove the lower splash shield, and use the correct socket to replace the switch. A service manual for the 2UR-GSE engine specifies applying an adhesive to the threads and torquing the switch to a specific value (around 11 ft-lbf).
Is there a recall on the LC500 for oil pressure issues?
No, there are no active recalls or common Technical Service Bulletins (TSBs) for the engine oil pressure switch on the 2018-2024 Lexus LC500. A recall for a low-pressure fuel pump was issued for some 2018-2020 models, but this is an unrelated part.
What happens if I ignore a bad oil pressure switch?
The biggest risk is that you won't be alerted if your engine develops a real oil pressure problem. If the switch has failed and the warning light is always on, you might ignore it. If a real leak or pump failure occurs, you won't get a new warning, and you could end up with severe engine damage.
