Trending wide band o2 sensor wiring diagram - Lsu 4.9 is superior to lsu 4.2. The essential difference between lsu four.Nine and four.2 is that lsu 4.9 makes use of the reference pumping-current, whilst lsu 4.2 uses the reference air. What does this suggest? Let’s study this actual tale from the automobile industries: when bosch first designed a wideband oxygen sensor, a reference air mobile became used to provide a reference of stoic air-gasoline-ratio, or afr. The generation changed into to maintain the pumping cell balanced with the reference air cell, with the aid of pumping the oxygen out of the pumping mobile. The pumping present day turned into the indication of the actual afr in the exhaust gasoline. The larger the pumping contemporary, the extra the oxygen within the exhaust, and vice versa. Consequently the reference air was critical to the accuracy of the sensor, as it changed into the reference. It worked nicely inside the lab, but now not so accurate within the actual life, because the surroundings across the sensor on a car changed into a great deal worse. The reference air cell will be contaminated by way of the encompassing pollutants. As soon as the reference air turned into contaminated, the whole characteristics of the sensor have been shifted to the lower facet. It was known as “feature shifted down”, or csd, within the industries. This became the biggest problem of lsu four.2 that passed off in a few early oem programs. And it precipitated the big nice issue to bosch. To restore this hassle, bosch redesigned the lsu sensor, and came up with lsu four.Nine model. The lsu 4.Nine sensor got rid of the reference air. As an alternative, it used a reference pumping present day which turned into equal to the reference air, however without having the bodily air in the cell. So the technology became: the real pumping modern-day become compared to the reference pumping current to maintain the stability. The actual pumping cutting-edge become nonetheless the indication of the real afr, but the reference changed into a calibrated electrical signal, and stayed identical all the time, all the conditions. 1x new proper bosch lsu 4 9 5 cord wide band oxygen sensor lovable bosch wideband o2 wiring diagram 1x new proper bosch lsu 4 nine 5 wire huge band oxygen sensor lovely bosch wideband o2 wiring diagram 1x new genuine bosch lsu four 9 five wire extensive band oxygen sensor lovely bosch wideband o2 wiring diagram.
