Deep within the heart of your engine compartment lives two parts that are dedicated to fighting the war on pollution. They will exist until the last fuel using vehicle has been replaced with electric transportation. Introducing the oxygen sensor; a silent monitor of air-fuel mixture, dedicated to help your engine use fuel as cleanly as possible.
If you're a Torrance driver that routinely gets their tune-up, it is important to check and document the status of all your fuel and emission parts, including your o2 sensors. Click here if you're experiencing check engine lights, erratic engine behavior, or simply need a tune-up.
The oxygen sensors police the exhaust coming out of the engine to help make sure the right amount of fuel is being used. A working oxygen sensor means:
Optimal performance.
Fuel economy.
Less pollution.
The oxygen sensor connects into the exhaust system of your vehicle. It monitors the amount of oxygen that remains in the exhaust after the engine has burned its fuel. If there were more than normal oxygen levels present then the fuel mixture was too lean. If there were not enough oxygen levels leftover then the fuel mixture was too rich.
The oxygen sensor reports this exhaust oxygen level to the engine computer in real time. Based on that data, the computer can instantly adjust the fuel mixture for the most optimal level at that moment. This keeps the engine running as efficiently as possible. Without the constant fine tuning from the oxygen sensor, the engine computer would have to guess at the right fuel mixture. Keep in mind that a check engine light is merely a warning that there is an issue that something needs to be diagnosed. For example you may have a bad O2 sensor that causes an engine light warning or it could be something as simple as a bad PCV valve that's causing you engine woes. Always use a qualified mechanic with a professional diagnostics scanner before arriving to any conclusions or changing out parts.
Let’s take a closer look at how South bay drivers in Torrance can make sure their oxygen sensors are in good working order at their next scheduled tune-up. We’ll talk about signs of a failing sensor and the steps for replacing one yourself or having it done professionally. Keeping your oxygen sensor working properly is one of the best investments to protect your ride and the air you breathe.
What Is The History Of Oxygen Sensors?
The 40’s and 50’s gave us hot rods, but the 60’s and early 70’s gave us sexy muscle cars. However, with great power comes great smog! Californians, for example, noticed that they couldn’t “notice” things in the sky like they used to. Our rose colored glasses that filtered our visions during the industrial revolution were replaced with the brownish/ yellowish tint of pollution. Cars switched from leaded to unleaded gas and California ultimately led the charge towards the strictest emission standards in the nation. Cars by the late 70’s came with smog devices in an effort to minimize the transportation sector's carbon footprint. However, one of the components that became part of the automobile smog systems were created earlier on.
In the 1960s, Robert Bosch GmbH began development of O2 sensor technology. These sensors were designed to address the air pollution fiasco by measuring the amount of unburned oxygen in a vehicle's exhaust, providing feedback to the ECU. In 1976, Robert Bosch introduced the first automotive lambda sensor, which was initially used by Volvo and Saab. The introduction of oxygen sensors enabling more car manufacturers efficient combustion solutions that reduced emissions. Most cars have at least two oxygen sensors - one before and one after the catalytic converter. The first one measures the raw exhaust from the engine to optimize combustion. The second one checks the converter’s cleanup performance. Inside the sensor is a special material that generates a small electrical voltage based on the oxygen concentration. The higher the exhaust oxygen, the higher the voltage signal to the computer. A constantly changing signal means the computer can make constant mixture corrections.
The following list explains the advancements of oxygen sensors from past to present:
Electronic fuel injection (EFI) emerged in the 1970s/1980s and relied on oxygen sensors for precise air-fuel measurement.
Oxygen sensors became integral to EFI systems for optimizing efficiency and emissions.
Hot wire sensors were used first but had limitations.
Digital oxygen sensors later provided enhanced precision by outputting a direct digital signal.
MEMS technology stands for Microelectromechanical Systems. It is a technology that integrates tiny mechanical and electrical elements on silicon chips to create miniaturized sensors and actuators. Mems technology was later introduced to O2 sensors.
Today, oxygen sensors are a crucial component in modern EFI engines.
They optimize performance, fuel economy, and emissions reduction.
Oxygen sensors will remain essential for fossil fuel burning engines until they are retired.
What Are Oxygen Sensors Made Of?
Oxygen sensors are made from durable and quality materials. The specific materials used vary depending on the type of oxygen sensor and the manufacturer. Here's a breakdown of the key components and their materials:
Sensing Element: The sensing element is the heart of the oxygen sensor, responsible for measuring the amount of unburned oxygen in the exhaust system. It’s usually made from zirconia ceramic and a platinum film. Zirconia conducts oxygen ions at high temperatures. The platinum film on the sensor acts as an electrode that generates an electrical signal that is based on the amount of oxygen found present in the exhaust.
Housing: The housing protects the sensing element from:
Moisture.
Debris.
Extreme temperatures.
It is typically made of stainless steel or aluminum, helping the O2 sensor resist corrosion.
Electrical Connections: The electrical connections that connect to the ECU are typically made of insulated copper wires.
Protective Layer: The sensing element is protected by a ceramic or epoxy coating.
Heater Element (Some Vehicles): Some oxygen sensors, particularly those used in cold climates, incorporate a heater element to maintain a consistent operating temperature and accurate oxygen measurements. This heater is typically made of a nickel-chromium alloy.
What Are The Signs That Your Oxygen Sensors Are Going Bad?
Torrance drivers should find an auto repair shop that specializes in tune-ups if they can. Here are some signs that your oxygen sensors may be going bad:
Check Engine Light: The Check Engine Light is a general warning that something is wrong with your car's engine. If your Check Engine Light is on, it could be a sign that your oxygen sensor is malfunctioning.
Decreased Fuel Economy: If you're noticing that your car is getting worse gas mileage than usual, it could be a sign that your oxygen sensor is not working properly.
Increased Emissions: If your car is producing more exhaust smoke than usual, it could be a sign that your oxygen sensor is not working properly.
Engine Performance Issues: If you're noticing that your car is running rough, hesitates when you accelerate, or has lost power, it could be a sign that your oxygen sensor is not working properly.
Sulfur Smell: If you notice a sulfur smell coming from your exhaust, it could be a sign that your oxygen sensor is malfunctioning.
If you are experiencing any of these signs, it is important to have your oxygen sensor checked by a qualified mechanic. They can diagnose the problem and recommend the appropriate course of action. Here are some additional things to keep in mind about oxygen sensors:
Oxygen sensors typically last between 30,000 and 60,000 miles.
Oxygen sensors can be damaged by contamination, aging, and mechanical damage.
