12573107 Oil Pressure Sensor with Socket for Chevy

RICHWEI 12573107 oil pressure sensor kit is a direct-fit replacement sensor and installation socket for many GM V6 and V8 models from the early 2000s, restoring accurate oil-pressure reporting.

This kit includes one oil pressure sensor, an inline filter, and a 1 1/16" socket that fits a 3/8" drive or 1 1/8" hex wrench. It replaces part numbers such as 12573107, 12677836 and 12616646 and is manufactured to match the original sensor's electrical and thread specifications. The sensor is commonly used across Chevrolet, GMC, Cadillac, Buick, Pontiac, Isuzu, Hummer and Saab models equipped with 4.8L–7.0L engines from the 2000s era. Before ordering, confirm fitment with your vehicle year, engine displacement and the dropdown selector to ensure compatibility.

How will this sensor affect my dash readings and engine monitoring?

Replacing a faulty sensor with a properly matched unit helps restore accurate oil pressure readings to the instrument cluster or ECM. That means more reliable oil-pressure warning lights and better diagnostic clarity when troubleshooting engine oil circulation concerns.

• Restores accurate voltage/pressure signal to the ECU and dash gauge.
• Helps prevent false oil-pressure warnings that can mask real issues.
• Maintains OEM thread and connector fit for consistent electrical contact.
