Oxygen Sensor Buyer’s Guide

What Is an Oxygen Sensor?

Modern vehicles are equipped with oxygen sensors, which monitor the amount of oxygen in the exhaust pipe. This part works with the engine control module to maintain your vehicle’s performance and keep its emissions in check.

An automotive oxygen sensor detects the amount of unburned oxygen in the engine exhaust and references it to the amount of oxygen in the atmosphere. It creates a voltage signal based on the difference that is sent to the engine control computer. The amount of voltage indicates whether the air/fuel mixture is rich or lean. In response, the computer varies fuel injector pulse width (on time) to control the air/fuel mixture. Although the computer also relies on inputs from other sensors regarding engine temperature, engine load, and throttle position, the oxygen sensor is the one that provides feedback and allows the engine control system to operate in “closed loop”, the operating mode that provides optimal catalytic converter efficiency and minimal exhaust emissions. When an oxygen sensor gets old or is damaged by contaminants, it may not be able to provide a timely signal to the computer. Without accurate feedback the computer can’t adjust the air/fuel mixture to suit engine operating conditions, which may result in increased emissions. If you’re in need of a replacement oxygen sensor, you’ll find what you need to restore performance and emissions compliance here on our digital shelves.

An oxygen sensor has a zirconium dioxide sensing element coated on both sides with platinum, which also serves as electrodes, encased in ceramic. The electrodes are connected to wire leads that attach to the vehicle wiring harness and the ceramic enclosure is encased in a steel shell. The steel shell is threaded for installation in the exhaust and it protects the sensing element. Openings in the steel shell adjacent to the sensing element tip allow the sensor to be exposed to exhaust gas. All modern oxygen sensors contain a heating element that is also connected to the wiring harness. Openings at the top of the sensor allow outside air to enter the sensor, which is then heated. When heated, oxygen ions move from the inside to the outside platinum layer, and the potential difference generates a voltage. When the air/fuel mixture is rich and there is little unburned oxygen in the exhaust, up to 0.9V is generated. When the mixture is lean and there is a high concentration of unburned oxygen in the exhaust, the voltage signal will fall to 0.1V.

Oxygen sensors operate at approximately 600°F (315°C), and the heater is included in modern sensors to allow them to heat up faster so the system can quickly go into closed loop. When viewed on a diagnostic oscilloscope, an upstream oxygen sensor at operating temperature should produce a uniform waveform that varies between 0.1V and 0.9V with a midpoint of approximately 0.45V. The downstream oxygen sensor is also known as a catalyst monitor because it indicates converter efficiency. In contrast to the upstream sensor, the downstream sensor should have a relatively flat waveform at approximately 0.45 volts if the catalytic converter is functioning properly. If the downstream sensor signal and diagnostic scope waveform are similar to the upstream sensor, it means that the converter is not functioning efficiently. If this occurs a Diagnostic Trouble Code (DTC) will be set in the computer and the CHECK ENGINE light will illuminate.

 

No matter what vehicle you’re working on or the type or position of the defective oxygen sensor, we have the replacement sensor needed to restore proper performance, reliability, fuel economy, and emissions compliance. We offer components that are manufactured to original equipment specifications, so when repairs are completed you can count on the performance your vehicle was designed to deliver. In addition to oxygen sensors, we have related components that may be needed to affect a complete repair including connectors, relays, wiring harnesses, extension harnesses, bungs, nuts, plugs, gaskets, and more.
