Rear Othermotive™ Premium Oxygen Sensor (932-14066) by Walker Products®. Walker oxygen sensors are precision made for outstanding performance and manufactured to meet or exceed all original equipment specifications and test requirements. The oxygen sensor is a device which determines the oxygen content of the exhaust gas. Since the amount of oxygen in the exhaust gas is a very good indicator of combustion efficiency, it is also the best place to monitor the air fuel ratio. Walker products, an ISO 9001-2008 / ts16949 certified company, specializes in the manufacturing and distribution of fuel system components and automotive engine management products. Walker is committed to meeting or exceeding OEM or equivalent standards and specifications. This effort is backed by walker's own manufacturing, product management and engineering expertise.

Walker premium oxygen sensors are 100% oem quality. Oxygen sensors are designed to determine the oxygen concentration in exhaust gas. Walker oxygen sensors are precision made for outstanding performance and manufactured to meet or exceed all original equipment specifications and test requirements. These superior sensors feature only the highest quality material available. Replacing an improperly functioning oxygen sensor with a walker sensor will increase fuel economy, improve engine performance, and produce lower emissions.
They are an automotive iso9001/ts 16949 certified company, with un-paralleled customer service, marketing, and shipping. Walker products electronic and paper catalogs are designed for today's fast paced marketplace, along with walker products eye catching packaging. since 1946, Walker products has been the number one choice for the engine management sensors and fuel system components needed for your vehicle.
Located in the exhaust system, the oxygen sensor produces a voltage proportional to the amount of oxygen in the exhaust versus the air (<150 mv lean & >750 mv rich). This data is used to control the air-fuel mixture through port or tfi injectors and carburetors. Sensors are monitored or checked anywhere from 4 to 100 times per 2nd. The air-fuel mixture is thus always moving from rich to lean averaging very close to stoichiometric (ideal) ratios.
The ceramic sensor body is contained in a housing which protects it against mechanical effects and facilitates mounting. The ceramic body is made of stabilized zirconium dioxide (zirconia). Its surfaces are coated with electrodes made of a gas-permeable platinum layer. in addition, a porous ceramic coating has been applied to the side exposed to the exhaust gas. This coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
Walker oxygen sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements.
