Many drivers of modern vehicles are oblivious to the critical role oxygen sensors play

Instead, they simply enjoy the benefits of the contemporary electronics which are seamlessly integrated with the unparalleled driving experience brought to modern vehicles by technological advancements. At the same time, the development of EFI has provided a whole range of new parts and a new wave of thinking, with function and quality new key considerations.
While this may be the case, the astute motor-vehicle repairer knows that the sole purpose and existence for the oxygen sensor (two-step and wide band only to name a few) is to ‘fine-tune’ the air to fuel mixture as you drive, taking the role of a very sophisticated computerised ‘pseudo-exhaust-gas-analyser’. As such, it is a significant part of the fuel efficiency system as well as the environmental management system.
Motospecs says the perceptive motor mechanic also knows that the ‘fidelity’ of the generated signal by the oxygen sensor is of the utmost importance. This is because the Engine Control Module (ECM) uses this signal as a feedback to ‘fine-tune’ the fuel mixture as one drives. Therefore, using nonspecific parts can adversely affect vehicle performance.
There are many oxygen sensors available, with the most common ones being the Two Step Oxygen Sensors which operate within the ECM’s ‘closed-loop’ mode, generating an alternating DC voltage varying from 0.1v to 0.9v signifying an air-fuel ratio of lean and rich respectfully.
The other most common oxygen sensors, explains Motospecs, are the sophisticated wide band sensors which send a current of +2 and –2 milliamps to and fro (Nernst cell). These are now used to linearly control the air fuel ratio between 0.7 to 2.2, maintaining the correct air fuel ratio control.
Across the many different makes and models of vehicles, each is fitted with a different type of Oxygen Sensor which varies in physical shape, size and the length of wire as well as the correct interfacing connecting terminals and the wide bands with their calibrated trimming resistors within the connectors.
All of these factors can make replacement very difficult and time-wasting for the mechanic. Now however, Motospecs says the search for exact parts has been solved by the Fuelmiser Oxygen Sensor range, which now includes an additional 400 part numbers to bring the range to in excess of 860 part numbers.

Fuelmiser – the broadest range sourced from world leading manufacturers
Motospecs explains that Fuelmiser is a trusted brand name across Australia, with a proud reputation for supplying the automotive aftermarket with an extensive range of high-quality parts. In fact, it says, it has the broadest range sourced from world leading manufacturers.
Across more than 20 years, the wide range of engine management, ignition and fuel system components has grown to more than 5,500 individual parts across over 40 product groups, which the company says reflects the confidence mechanics and workshops have in its products.
“Engine management and fuel system components are critical in keeping vehicles on the road, and when you choose Fuelmiser, you can be 100 percent confident in the quality and reliability of each and every product,” Fuelmiser Category Manager, George Soultis, said.
“With Fuelmiser, you are not only purchasing OE standard components, you are choosing a brand with a proven ability and long history supplying the market with top quality parts at very competitive prices.”
Motospecs says its Fuelmiser range of Oxygen Sensors are direct fit, and meet or exceed OEM specifications in length and plug type, making Fuelmiser the ultimate choice for direct replacement of failed sensors. Further, this doesn’t compromise the integrity of ECM’s ‘closed-loop’ operation, thus maximising fuel mixture control, it says.
Mechanics have looked for a simple solution to a complex problem for years. Finding the correct part “first time-every time” means less waste and greater efficiencies for everyone in the supply chain. Motospecs says its resources have replaced the trial and error process to a comprehensive, methodical and accurate process that makes it much more efficient for finding the right parts.

Inside the box: labels highlight product caliber
Motospecs says it has gone one step further to assure customers of the exceptional quality of every component that bears the Fuelmiser name.
“To highlight to our customers just what they’re getting when they choose Fuelmiser, we have introduced product labels that showcase exactly what’s in each box,” George said.
“Did you know that Fuelmiser has always sourced the complete range of products from world-leading OEM brand manufacturers such as Hyundai, Kia, Mitsubishi and Toyota? Or that Fuelmiser also sources quality branded parts from VDO, Delphi, Facet, FAE, Valeo and YEC?
“The labels allow for quick, easy identification of the superior brand(s) that have been included in each product box, providing mechanics and workshop owners with total confidence in the quality and reliability of Fuelmiser components.
“Fuelmiser has always sourced products from world-leading brands, and we have strong, ongoing relationships with these manufacturers. With our new easy-to-read labelling, mechanics and workshop owners can clearly see the quality that’s contained in every Fuelmiser box. This approach differentiates us even further from our competitors.”

A constantly developing range
Motospecs is continuously reviewing and sourcing new Oxygen Sensors from the world’s leading manufacturers including Denso, Delphi, FAE Europe, Facet Europe and Walker USA. This range covers everything from traditional two wires, up to the latest technology six wire sensors.
Furthermore, where applicable, these manufacturers are producing sensors compliant with the latest stringent Euro 6 Emission Standard. To achieve this, the latest and most exact equipment is used, says Motospecs.
The enhanced range of Fuelmiser products, now totaling over 860 part numbers, is available to mechanics via all electronic catalogues and includes a complete range of images and identification drawings.
