Description

The oxygen sensor measures combustion efficiency based off the amount of oxygen in the exhaust gas.Walker Products Engine Management and Oxygen/Air-Fuel sensors have been engineered and developed to be an Original Equipment Manufacturers replacement for many vehicles worldwide. Every part number is manufactured for the specific application, fitment position on the vehicle, and will provide the relevant diagnostic system feedback as required by the ECU. Newer vehicles will store fault codes in the ECU, some will relate to the affected sensor and its associated systems. A failed sensor might make itself known by causing the engine to run poorly, increase fuel consumption, exhaust emissions, or illuminating a (MIL) malfunction indicator light. The sensor, wiring harness, and connector should also be checked for physical damage. This will most likely also cause their operational life to be shortened. We are an Automotive ISO9001/TS 16949 certified company, with un-paralleled customer service, marketing, and shipping. Our electronic and paper catalogs are designed for todays fast paced marketplace, along with our 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. -¬ 2023 Walker Products Inc. All rights reserved.

Features

• Coated in with electrodes made of a gas-permeable platinum layer.
• Measures oxygen levels to fine-tune air-fuel mixture, improving fuel economy and saving costs.
• Monitors exhaust gases and reduces pollutants for a cleaner environment.
• Coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
• Determines the oxygen content of the exhaust gas, monitoring the air fuel ratio for combustion efficiency.
