Walker Products Oxygen Sensors

Walker Products Oxygen Sensors play a critical role in maintaining optimal engine performance and fuel efficiency. Positioned in the exhaust system, these sensors continuously monitor the oxygen levels in exhaust gases, generating a voltage signal that helps the vehicle's onboard computer regulate the air-fuel mixture. When the mixture is lean (<150 mV) or rich (>750 mV), the sensor sends real-time feedback, ensuring the engine maintains a near-stoichiometric balance for maximum efficiency. Depending on the vehicle, this process occurs anywhere from 4 to 100 times per second, allowing for precise fuel adjustments via PORT or TFI injectors and carburetors. Each Walker Oxygen Sensor is engineered with a high-quality ceramic body made from stabilized zirconium dioxide (zirconia). This durable material is encased in a protective housing to prevent mechanical damage and ensure reliable mounting. The sensor's platinum-coated electrodes are designed to allow optimal gas permeability, while a porous ceramic coating shields the unit from contaminants, combustion residue, and particulates, extending sensor life and performance. Built to meet and exceed OEM specifications, Walker Oxygen Sensors provide enhanced engine response and performance, lower emissions for environmental compliance, improved fuel economy, and extended sensor lifespan. When it's time to replace a worn-out oxygen sensor, trust Walker Products for a direct-fit, high-performance solution that restores fuel efficiency, reduces emissions, and optimizes engine function for the long haul.
