Pentius Oxygen Sensors are designed to measure the proportion of oxygen in the vehicle exhaust gases. The sensor transmits signals to the Engine Control Unit (ECU) including air and fuel ratios, in order to establish the optimum operating range for the engine. A properly functioning oxygen sensor will improve fuel economy, maximize engine response and performance, and serve to reduce harmful or toxic emissions. Pentius Oxygen Sensors are constructed from durable materials that are corrosion and abrasion resistant, and meet or exceed OE specifications. Pentius offers nearly 700 premium quality, OEM-based, direct-fit Oxygen Sensors to facilitate quick installation while ensuring maximum longevity.
