removed. Options meeting this criteria include the. Most manufacturers of aftermarket wide-band Lambda controllers, pass this point on in their instruction manual in one form or another. The following comments come directly from Bosch: In the warm-up phase at engine start, the sensor is operated with reduced heater power. Without them, fuel injection management is essentially flying blind and has to resort to other less-desirable means to determine how much air and fuel need to be mixed. In contrast, most stand-alone aftermarket wide-band Lambda sensor controllers have the Lambda sensor itself as their only input. Excessive EGT While LSU4.9 sensors are actually rated to be able to withstand exhaust gas temperatures as high as 980 degrees C, if the sensing element goes too far above the controlled target temperature, then many aftermarket controllers will enter a fault mode. Eventually at high enough engine speed and load the heating circuit will be turned off completely. Wideband, these quantitatively measure lambda. Important warning: We are upgrading this part.4541.4301.4571 stainless steel. The voltage range may vary between car manufacturers.

One way to guarantee this is to power the forex-pankin oulun controller off of its own relay which is not turned on until after the engine is started. Their common use as a mass-produced part has driven the cost of these sensors down significantly over the years and they have become very popular in the after-market performance tuning industry. The ceramic sensing element consists of both a sensing circuit and a heater circuit. You get inventory warning during checkout and we recommend NOT to order this part until this text is updated (if you do order, the zinc-plated might be disappointing). Without engine speed information, they generally assume that the engine is started as soon as the ignition is turned on and the controller is powered. In the fault mode the controller may stop controlling the sensor which is effectively like not having the controller turned on at all while the sensor is fitted to the exhaust. The sensing circuit should ideally be kept at a constant temperature of 780 degrees C, which is where the heater comes into play. Their LSU range of wide-band sensors has been widely adopted by the OEMs and can be found on a huge number of production vehicles to accurately measure Lambda or the air/fuel ratio (AFR) in the exhaust system. But that is exactly what often happens in so many installations using after-market air/fuel ratio or lambda controllers designed specifically to work with these sensors. Never switch on sensor heating or the control unit before engine start. This process is known as thick-film technology and the end result is you effectively end up with a small electrical circuit that can survive in very high temperature environments like inside an exhaust system.
