Exhaust Systems

Oxygen sensors have been installed on Nissan trucks since the early 1980s. In 1995 and 1996, an additional sensor was added to monitor the catalyst efficiency. V-6 and V-8 engines in Nissan trucks...

Oxygen sensors have been integrated on vehicles for more than 30 years. Located in the exhaust system, they monitor fuel-to-air ratio and catalyst efficiency. While working in a hostile...

The Hyundai Elantra has been around since 1991, but wasn't made available in North America or Europe until 1993. Featuring different four-cylinder engines throughout its generational redesigns,...

While a catalytic converter is designed to last 10 years or more, several variables can make it die sooner. Nowadays, vehicles employ more than one converter, which increases the chances of...

The oxygen sensor monitors the fuel-to-air ratio in the spent exhaust near or on the manifold. Since the integration of OBD II (on-board diagnostics) in 1996, the amount of oxygen sensors on...

The Lexus S430 is actually classified as an SC430. The "C" stands for "coupe," which is the only way the S430 model is available. The 430 is related to the 4.3-liter V-8 engine. First manufactured...

Oxygen sensors have two basic functions: upstream sensors close to the manifold meter the amount of oxygen and burned fuel mixture in the exhaust; downstream sensors located near the catalytic...

Because oxygen sensors monitor the fuel-to-air mix ratio, most cars that did not integrate catalytic converters in their exhaust systems did not have oxygen sensors. The sensor not only regulates...

Depending on the year of the Ford Taurus, there may be two or more oxygen sensors present in the exhaust system. In the common 3.0-liter 6-cylinder models, there are four sensors. Read and...

The common engine in the Chevy Cavalier is the 2.2 liter four cylinder. A few models have a 2.4 liter engine. Both engines use two oxygen sensors. Oxygen sensors read the amount of air and burned...

The oxygen sensor(s) in a vehicle, simply put, are clever devices that monitor the amount of pollution the vehicle dispels from the exhaust system. Although the function of the oxygen sensor goes...

The oxygen sensor in a car is now an integral part of the exhaust system. Although it has been around for many years--since the implementation of On-Board-Diagnostics II in 1996--the amount of...

When one of the multiple oxygen sensors detect a lean mix of burned fuel to oxygen ratio or a bad circuit relay in your Ford Explorer Sport Trac, it will trip the "check engine" light. Finding the...

There are commonly two oxygen sensors in the 4.3 liter engine exhaust system on a Chevy truck. One is the "upstream" sensor located on the driver's side Y-pipe near the manifold and the other...

In 1996, GMC had 26 varieties of eight baseline models, all of which were pickup trucks, vans or SUVs. These models ranged in size from a quarter-ton to 1 ton, and though they had different...

The catalytic converters on the Chevy S10 has undergone many changes throughout the years. The older style S10s had the converter installed downstream in the exhaust system and were...

The oxygen sensors on your Jeep meter the amount of oxygen to fuel burning and communicate to the computer of the Jeep when there is a variance of rich or lean mixture. After a while, due to heat...

Most likely you have multiple oxygen sensors in your Jeep Cherokee. Figuring out which one needs to be replaced will be more challenging than actually replacing it. A code reader can condemn and...

Oxygen sensors are an integral part of the engine of today's cars. Not only do oxygen sensors help with gas mileage and the overall performance of the car, but they also decrease pollution and...

The Chevy Blazer has the same 4.3 liter engine, the same chassis and the same exhaust components from 1994 to 1999. This includes the two oxygen sensors. The bank one sensor is located on the left...

All vehicles come equipped with small engine components called engine oxygen sensors. While there are many different types of oxygen sensors that perform an array of different functions, a faulty...

The catalytic converter is part of a vehicle's exhaust system and serves to reduce the amount of toxic gases emitted into the atmosphere. These surprisingly simple components have served to...

The oxygen sensor informs a car computer of the level of oxygen being burned into the fuel. The computer utilizes this information to regulate the mixture of fuel to oxygen. Installing the oxygen...
