2013-2021 Lexus LX570 Engine Oil Pressure Switch Replacement Guide
Is your oil pressure light on? This guide will help you understand if a faulty engine oil pressure switch is the problem.
- Never drive your vehicle if the oil pressure warning light is on; always check the oil level first to rule out actual low oil pressure.
- A faulty switch is the most common cause of a false oil pressure warning when the oil level is normal.
- Replacement is a simple and affordable DIY job for most owners.
- For this critical sensor, choosing a Genuine Lexus part or a top-tier aftermarket brand like Standard Ignition is recommended.
Is Your LX570 Engine Oil Pressure Switch Failing?
A failing oil pressure switch can be alarming because its symptoms mimic actual low oil pressure. The key difference is that a bad switch provides a false reading. Here are the most common signs that the switch itself is the problem.
Symptoms of a Bad Oil Pressure Switch
- Oil Pressure Warning Light: The red oil can symbol on your dashboard may light up, flicker, or stay on, even when the oil level is correct. This is the most frequent symptom.
- Incorrect Gauge Reading: The oil pressure gauge on your instrument cluster might behave erratically. It could be stuck at zero, maxed out, or jump around randomly.
- Check Engine Light: In some cases, a faulty oil pressure sensor can trigger the Check Engine Light.
- Visible Oil Leak: The switch itself can develop a leak over time. You may notice oil residue on the sensor or small drips underneath the vehicle.
Choosing the Right Aftermarket Part
For a premium vehicle like the Lexus LX570, part quality is important. While the original Lexus (OEM) part is always a safe bet, high-quality aftermarket parts offer a reliable and more affordable alternative.
- OEM (Original Equipment Manufacturer): The genuine Lexus part (part numbers 83520-60051 or 83530-60020) offers a guaranteed fit and the same performance as the one installed at the factory. The cost is higher but provides peace of mind.
- Top-Tier Aftermarket (Rostra, Standard Ignition): Brands like Standard Motor Products (SMP) and Rostra are well-regarded in the industry. SMP, a company with over 100 years of experience, manufactures its parts in certified facilities and performs extensive testing. These brands are a solid choice for a balance of quality and value.
- Standard Aftermarket (True Tech): True Tech is a brand line from Standard Motor Products, offering a dependable replacement part that meets quality standards for a lower price point.
Cost of Replacing the Engine Oil Pressure Switch
The total cost depends on whether you do the job yourself or take it to a repair shop. The part itself is not very expensive.

Frequently Asked Questions
Can I replace the LX570 oil pressure switch myself?
Yes, this is a good DIY task for a beginner. The process involves safely raising the vehicle, locating the sensor on the engine block, unplugging the electrical connector, and unscrewing the old switch to install the new one. It typically requires basic hand tools and should take less than an hour.
What happens if I ignore a bad oil pressure switch?
Ignoring it is risky. If the switch is faulty and constantly triggers the warning light, you might ignore a real low-oil-pressure event in the future, leading to catastrophic engine failure. If the switch has failed and can no longer detect a problem, your engine is left unprotected without a warning system.
My oil pressure light came on, but my oil level is full. Is it the switch?
If your oil level is full and the engine is running smoothly with no unusual noises, a faulty oil pressure switch is the most likely culprit. However, the problem could also be a failing oil pump or clogged oil passages, which a mechanic should diagnose properly.
Are there any recalls for the LX570 oil pressure switch?
No, as of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) for the engine oil pressure switch on the 2013-2021 Lexus LX570. Recalls for this vehicle have focused on other components like the fuel pump and airbag sensors.
