02 Sensor Plug

The 02 Sensor Plug from FAST Electronics is a precision-engineered oxygen sensor connector designed for engine management systems requiring reliable exhaust gas monitoring. This stainless steel plug serves as a critical interface between your vehicle's oxygen sensor and the engine control unit, ensuring accurate fuel mixture feedback and optimal combustion efficiency. Engine technicians and automotive enthusiasts rely on quality sensor plugs to maintain proper sensor operation and prevent diagnostic trouble codes that can trigger check engine lights.

Constructed from stainless steel for superior corrosion resistance, this 02 Sensor Plug features an 18 mm × 1.50 male thread configuration that provides a secure, leak-free connection in high-temperature exhaust environments. The natural finish preserves the material's inherent durability while resisting oxidation from thermal cycling and moisture exposure. The compact design—measuring 1.65 × 0.95 × 4.05 inches and weighing just 0.08 lbs—enables easy installation in tight engine bay spaces without compromising structural integrity or sensor signal clarity.

This sensor plug is ideal for technicians rebuilding fuel injection systems, performing oxygen sensor replacements, or diagnosing emission system faults on vehicles equipped with standard threaded sensor bosses. The 18 mm × 1.50 thread pattern is commonly found across domestic and import platforms, making this a versatile replacement component for fleet maintenance shops and individual rebuilders. Proper installation ensures uninterrupted sensor functionality, stable lambda readings, and compliance with OBD-II monitoring protocols—critical for vehicle performance and emissions certification.
