The basic job of the sensor is to monitor the air fuel mixture under idle, moderate Acceleration and cruise conditions. Under heavy Acceleration the oxygen sensor goes into open loop, which basically means that the engine management computer system ignores the oxygen sensor. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio. Oxygen sensors, also known as Lambda sensors or oxygen sensors among some vehicle manufacturers, are among the most sensitive and critical components on your car's engine. Earlier fuel injection systems employed one oxygen sensor in the exhaust system to maintain closed-loop air/fuel mixture control. However, today's engines may use as many as four sensors, which monitor not only exhaust gas oxygen content but catalytic converter efficiency as well. In order to perform these functions properly, the sensors must adhere to OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt driveability and illuminate the malfunction indicator, resulting in costly and time-consuming repairs. DENSO First Time Fit® oxygen sensors are designed to meet those tolerances and more.Features & Benefits Corrosion-Resistant Stainless Steel Construction Porous PTFE Filter - Allows Atmospheric Oxygen To Enter The Sensor Without Permitting Water Or Engine Contaminants To Seep Into The Casing Refined Zirconia Element Improves Sensor Response Robotic Laser Weld Double Protection Cover - Maintains Proper Unit Temperature For Quicker Response Times And Protects The Ceramic Element Against Silicone And Lead Poisoning Stainless Steel Housing - Resists Corrosion And Contamination With A Rugged, Watertight Body Aluminum-Oxide Trap Layer - Keeps Silicone And Lead Outside The Ceramic Element Through DENSO's Exclusive Design, Preventing Damage To The Platinum Electrode Superior Design Maximizes Engine Performance While Reducing Fuel Consumption And Harmful Emissions Ensures Smog Test Compliance Limited 90 Day Warranty This Fits1979-1981 Buick Century1980-1981 Buick Electra1980-1981 Buick Estate Wagon1979-1981 Buick LeSabre1979-1981 Buick Regal1979-1981 Buick Riviera1979-1980 Buick Skyhawk1982-1982 Buick Skyhawk1979-1981 Buick Skylark1993-1993 Cadillac 60 Special1987-1992 Cadillac Allante1980-1984 Cadillac Commercial Chassis1980-1984 Cadillac DeVille1988-1995 Cadillac DeVille1980-1984 Cadillac Eldorado1987-1993 Cadillac Eldorado1980-1984 Cadillac Fleetwood1986-1992 Cadillac Fleetwood1980-1984 Cadillac Seville1988-1993 Cadillac Seville1980-1981 Chevrolet Camaro1980-1981 Chevrolet Caprice1980-1981 Chevrolet Chevette1980-1981 Chevrolet Citation1980-1981 Chevrolet Corvette1979-1981 Chevrolet El Camino1980-1981 Chevrolet Impala1980-1981 Chevrolet LUV1979-1981 Chevrolet Malibu1979-1981 Chevrolet Monte Carlo1979-1980 Chevrolet Monza1999-2002 Daewoo Lanos1999-2002 Daewoo Leganza1999-2002 Daewoo Nubira1979-1981 GMC Caballero1979-1981 Oldsmobile 981979-1981 Oldsmobile Custom Cruiser1979-1981 Oldsmobile Cutlass1979-1981 Oldsmobile Cutlass Calais1980-1981 Oldsmobile Cutlass Cruiser1979-1980 Oldsmobile Cutlass Salon1979-1981 Oldsmobile Cutlass Supreme1979-1981 Oldsmobile Delta 881982-1982 Oldsmobile Firenza1979-1981 Oldsmobile Omega1979-1980 Oldsmobile Starfire1979-1981 Oldsmobile Toronado1979-1981 Pontiac Bonneville1979-1981 Pontiac Catalina1979-1981 Pontiac Firebird1979-1980 Pontiac Grand Am1979-1981 Pontiac Grand LeMans1979-1981 Pontiac Grand Prix1982-1982 Pontiac J20001979-1981 Pontiac LeMans1979-1981 Pontiac Phoenix1979-1980 Pontiac Sunbird1981-1981 Pontiac T1000 14259221 042511120013 0.5000lbs 0.00 0.00 0.00
