KoiLuvGo Oil Pressure Sensor 12673134 — Direct-Fit OE Replacement for GM Trucks & SUVs

If your oil pressure gauge is erratic or the oil light is on, a failed sensor is a common cause. This KoiLuvGo assembly replaces OEM part 12673134 and compatible numbers, fitting a wide range of Chevrolet, GMC, Cadillac and related GM-platform vehicles from model years roughly 2003–2020. Built from durable components intended for engine-bay conditions, it restores correct pressure feedback to the instrument cluster without modification.

How does this sensor restore correct oil pressure readings?

The sensor converts mechanical oil pressure into an electrical signal the vehicle’s ECU or gauge cluster can interpret. When the original sensor fails, readings can become intermittent or constant, triggering dashboard warnings.

• Direct electrical fit for OEM connectors and harnesses.
• Designed to match OEM pressure-response characteristics.
• Corrosion-resistant materials for reliable contact and sealing.

Which vehicles and part numbers is this compatible with?

KoiLuvGo’s assembly is engineered as a direct replacement for part 12673134 and many equivalent numbers. It's compatible with numerous GM cars, trucks and SUVs across Chevrolet, GMC, Cadillac, Buick, Pontiac, Hummer, Saab and Isuzu model families covering several engine sizes.

• Replaces OEM numbers such as 12673134, PS690, 12596951 and others.
• Fits Chevy Silverado, Tahoe, Suburban, Avalanche, Express and Corvette variants listed by year and engine.
• Also compatible with GMC Sierra/Yukon/Savana, Cadillac Escalade/CTS, Buick, Pontiac, Hummer, Saab and Isuzu models where listed.

What should I expect during installation and maintenance?

Installation is straightforward for most mechanically inclined owners or a quick job for a technician: unplug the electrical connector, remove the old sensor, install the replacement with proper torque, and reconnect the wiring. No additional programming is typically required because the unit is an electrical analog replacement for OEM sensors.

• Simple plug-and-play electrical connector match.
• Replace with correct torque and sealant where recommended by vehicle manual.
• Inspect wiring and mounting threads for oil contamination before fitting.

How do I tell if I need this sensor now?

Symptoms pointing to a faulty oil pressure sensor include a sudden or persistent oil-pressure warning light, fluctuating gauge needle, or incorrect low/high pressure readings without mechanical loss of oil. Diagnosing may involve checking wiring and using a mechanical gauge to verify actual oil pressure.

• Intermittent or constant oil warning light illumination.
• Gauge jumps, sticks, or shows implausible pressure values.
• No external oil leaks yet dashboard warns about pressure.

Who is this for: Owners, technicians and fleet managers of GM-platform vehicles who need a reliable, OEM-compatible oil pressure sensing solution. If you own a compatible Silverado, Sierra, Tahoe, Suburban, Escalade, or any listed model experiencing inaccurate oil-pressure indications, this KoiLuvGo replacement is intended to restore dashboard accuracy without custom wiring or programming.
