Oil Pressure Sensor for Chevrolet GMC Buick Cadillac Yukon

ADdormorn PS508 oil pressure sensor is a direct-fit replacement sensor and socket kit that restores accurate oil pressure readings for Chevrolet, GMC, Buick and Cadillac 4.8–6.2L engines from 2009–2020.

If your dashboard oil pressure warning or gauge behaves erratically, a failing oil pressure switch can be the cause. The ADdormorn PS508 assembly is engineered as an OE-style replacement for many GM vehicles, supplying the sensor, a protective filter, and a dedicated socket to make swap-out quicker. It’s built to withstand common failure modes like high under-hood temperatures and internal wear that degrade original sensors over time.

How will this sensor fix oil pressure warnings or inaccurate gauges?

Replacing a faulty switch with the ADdormorn PS508 restores the electrical signal the ECM and dash cluster expect, returning steady readings and removing false warnings. The kit’s filter helps prevent contamination-related failures that can cause intermittent signals.

• Direct-fit design matched to GM OE dimensions and connectors
• Includes filter to reduce particle ingress and prolong life
• Socket tool provided to remove the old sensor without extra parts
• Two-year replacement warranty for added confidence

Which vehicles and engines is this part compatible with?

The PS508 is validated for a wide range of GM platforms that use the 4.8L, 5.3L, 6.0L and 6.2L V8 engines across model years 2009 through 2020. It covers Chevrolet, GMC, Buick and Cadillac passenger and light-duty truck applications, plus select Hummer models that share the same sensor footprint.

• Fits Silverado 1500, Sierra, Suburban, Tahoe, Yukon, Escalade and Escalade ESV
• Compatible with Avalanche, Camaro, Corvette, Impala and Express applications
• Also fits Buick LaCrosse, Rainier; Cadillac CTS, CT6 and other GM sedans
• Check photos and vehicle-year compatibility before ordering to confirm connector type

How difficult is installation and what comes in the package?

Installation is straightforward for anyone comfortable working under the hood or with basic hand tools. ADdormorn includes the oil pressure sensor, a small protective filter, and a socket designed to access the switch location, which is commonly behind plastic covers or near the intake manifold.

• Package includes sensor, filter and removal socket for faster replacement
• Socket helps access switches located above the engine or behind covers
• Recommended: verify plug shape and compare with old sensor prior to install
• Follow vehicle service manual for proper torque and connector seating

What reliability and support can I expect after purchase?

ADdormorn designs and tests parts to match OE fit and function; the PS508 aims to resist heat-related failures and internal wear common to original switches. If the part arrives damaged or fails early, the included two-year replacement policy covers defects.

• OE-style validation for fit and electrical performance
• 2-year free replacement for eligible early-life faults
• Inspect connector and wiring during install to avoid false faults
• Contact seller with vehicle and part photos for fit confirmation if unsure

Who is this for? The ADdormorn PS508 oil pressure sensor kit is aimed at DIY mechanics, independent repair shops and fleet maintainers running GM 4.8–6.2L engines from model years 2009–2020 who need a reliable, OE-style replacement. If you’re troubleshooting an intermittent oil pressure light, an unstable gauge, or planning preventive maintenance on compatible Chevrolet, GMC, Buick, Cadillac or select Hummer vehicles, this kit supplies the sensor, filter and a removal socket to streamline replacement and help restore correct oil pressure signaling.
