Mobiletron has launched a brand new range of 5 wire oxygen sensors filling a gap that it has identified in the aftermarket. Using a 5 wire sensor will help to increase fuel economy as a result of the sensor mediating the optimum fuel mix and the vehicle will perform better due to a lower carbon build up in the engine.

Mobiletron say the main advantage of using a 5 wire oxygen, or Lambda, sensor is that it gives an exact reading as to what degree of rich or lean the fuel mix is, using the current sensing cell. Vehicles that use 4 wire sensors can only send a basic signal to the ECU which can recognize that the fuel mix is lean or rich, but not by how much.

The 5 wire sensor sends a more complex message to the ECU. The signal no longer simply tells the ECU the fuel mix is rich or lean, its signal gives the ECU a constant and variable voltage from 0 to 5 volts (with 0 indicating an extremely lean mixture and 5 volts indicating a very rich mixture). This enables the engine to maintain a better air to fuel mixture, because the ECU can adjust fuel injection according to these measurements provided by the oxygen sensor. By adjusting the fuel mix to the optimum level the engine will run more effectively and the emissions of the vehicle will be reduced.

Marketing Manager Mark Wilson says, "Mobiletron identified a gap in the market for 5 wire oxygen sensor supply after receiving many enquiries from our customers.  The addition of these new products allows us to cover this gap caused by the limited aftermarket supply”

The addition of the 5 wire sensors takes Mobiletron’s total Oxygen sensor vehicle coverage to over 89% and has added 70 new product lines to the current oxygen sensor range. This means the range now features over 650 parts, covering almost 15,000 vehicles types. Some of the popular models covered by the new 5 wire sensors are;

• BMW: 1 Series E87, 3 Series E90
• Citroen: Berlingo, C3, C4, DS3 and DS4,
• Mini: R56, R57, R55, .
• Peugeot: 206, 2008, 208, 3008, 308.
• Vauxhall: Astra MK5, Vectra, Zafira.

The new sensors will be on display at Mobiletron’s stand at Automechanika Frankfurt (Hall 3.0, stand E11) along with other new products such as the BMS Battery Management Solution and the COM02 Voltage Regulator Tester.
