Oxygen Sensors

Oxygen Sensors, found within the Electrical & Lighting > Engine Electronics section, are critical components in your vehicle's emissions control system. These sensors monitor the amount of oxygen in the exhaust gases, providing vital data to the engine control unit (ECU) to maintain the correct air-fuel mixture for optimal combustion and reduced emissions. Typically located before and after the catalytic converter, oxygen sensors ensure efficient engine performance, fuel economy, and compliance with emissions standards. Common sensor types include zirconia and titania, differing in construction and signal output. Examples in this assortment include Bosch sensors with part numbers 0281006282, 0281006009, and 0281002662, suitable for a wide range of passenger cars and commercial vehicles. Replacing faulty oxygen sensors can resolve issues like check engine lights and decreased fuel efficiency.
