Research on Air Fuel Ratio Sensor for Mazda RX8

The RX-8 was manufactured by Mazda between 2003 and 2012. It is valued by drivers for being sporty and yet economical. Its most impressive feature is the exceptional handling that Mazda is famous for. Zipping in and out of city traffic is a breeze in the Mazda RX8. But despite its popularity, Mazda announced that the RX-8 was to be discontinued in 2011. As of 2011, the RX8 was taken off the European market for failing to meet emissions standards.

Your Mazda RX8 air fuel ratio sensor is vital to meeting emissions standards. To understand why this is true, it is important to know how it functions and why it is so important.

It's All in the Mix

Meeting stringent exhaust emissions standards depend upon having the right air to fuel mixture. The Mazda RX8 air fuel ratio sensor, or AFR sensor, continuously monitors the air to fuel ratio of your exhaust. It sends a precise signal to the engine computer so that it can make adjustments in real-time relating to fuel mixture and timing. Since the air-fuel ratio sensor has a key role in the adjustment and tuning of the engine, signs of trouble are often related to performance.

How Can I Tell I Have a Faulty Mazda RX8 Air Fuel Ratio Sensor?

In addition to a lighter wallet because of all of the money you spend at the fuel pump, you might also notice a drop in power. A bad AFR sensor may delay sending the proper signal to your Mazda's computer and this will result in a delayed response for the entire engine. You might notice sluggish acceleration or loss of speed. Rough idling is another symptom of a bad AFR sensor. The incorrect messages being relayed to your computer can throw off the idle, causing it to fluctuate or drop below the correct level. If the problem is severe, you might even get to the point where your car completely stalls out.

Keep Your Mazda RX8 on the Road

Some states require that vehicles pass emissions tests. A malfunctioning Mazda RX8 air fuel ratio sensor may mean your car stays in the garage because of a failed test. It is always a good idea to be proactive and get a replacement ASAP, if you suspect a problem.

RX8 O2 sensor replacement or AFR replacement does not have to be expensive or complicated at partsgeek.com. For example, Mazda RX8 front O2 sensor average prices are between $154 and $220.
