ENA Oil Pressure Sensor Switch for Chevrolet & GMC V8 Trucks (Direct-Fit, 1999–2002 Compatible)

ENA oil pressure sensor switch replaces factory part numbers like 12562267 and D1818A to restore accurate oil-pressure readings on compatible Chevrolet and GMC V8 engines.

If your oil pressure gauge or warning light is behaving erratically, a faulty pressure switch is a common and repairable cause. The ENA Oil Pressure Sensor Switch is built to match OE fitment for a range of Chevy and GMC V8 trucks and SUVs from late 1990s to early 2000s, offering a direct-fit replacement that simplifies installation and helps avoid false alerts.

Which vehicles will this ENA oil pressure sensor fit?

This sensor is manufactured to fit many Chevrolet and GMC V8 applications. It covers Silverado, Sierra, Tahoe, Suburban, Yukon, Avalanche, Camaro and select Pontiac Firebird models with engine displacements listed below. Always confirm compatibility with your VIN, vehicle year, and original part number before purchasing.

• Chevy Silverado 1500/2500/3500 (4.8L, 5.3L, 5.7L, 6.0L) model years 1999–2002 where specified.
• GMC Sierra 1500/2500/3500 and Yukon/Yukon XL for 1999–2002 V8 engines noted in fitment list.
• Other applications include Tahoe, Suburban, Avalanche 1500, Camaro and Pontiac Firebird 1999–2002 where indicated.
• Cross-references: 12562267, 19244505, PS303T, D1818A — verify against your vehicle’s part number.

How does the ENA sensor perform under real driving conditions?

ENA designed this switch for durability and consistent electrical performance in harsh under-hood environments. The metal housing and leak-proof threads protect internal components from oil and vibration, helping maintain reliable readings over time. It’s intended as a robust OE-style replacement rather than an upgraded performance sensor.

• Durable metal construction resists corrosion and mechanical wear.
• Leak-proof thread design minimizes chance of oil seepage after installation.
• Electrically compatible with original wiring harnesses for plug-and-play fit.

What should I expect during installation and setup?

The ENA oil pressure sensor switch is a direct-replacement part that installs in the original sensor location with standard tools. Installation generally requires basic hand tools, a safe lift or jack stands to access the sender, and care to torque the sensor to manufacturer specifications. No programming is necessary—once installed and tightened, the sensor communicates with the stock gauge or ECM the same way the original did.

• Direct-fit replacement — no special adapters required.
• Typical install time: 15–45 minutes depending on vehicle access.
• Includes one sensor and a 12-month warranty for peace of mind.

How do I confirm compatibility before buying?

Because multiple sensors and revisions exist across model years, verify fitment using your vehicle year, engine size, and original part number. Use the dealer or online VIN lookup tools or compare the old sensor’s numbers with ENA’s cross-reference list. If in doubt, consult a mechanic to avoid ordering the wrong component.

• Confirm original part numbers like 12562267, 19244505, D1818A before purchase.
• Use VIN or online fitment tools to double-check model-year compatibility.
• Contact ENA support or a trusted installer for fitment questions.

Who is this for: The ENA Oil Pressure Sensor Switch is aimed at owners and mechanics servicing late-1990s to early-2000s Chevrolet and GMC trucks and SUVs with the listed V8 engines who need a reliable, OE-style replacement sensor. It suits DIY installers seeking a direct-fit part and professional shops requiring a usable cross-reference to factory numbers. Please verify fitment with your vehicle details to ensure correct selection.
