AdBlue Sensor

An AdBlue sensor is a crucial component in modern diesel vehicles equipped with selective catalytic reduction (SCR) systems. AdBlue, also known as diesel exhaust fluid (DEF), is a solution consisting of urea and deionized water. It's injected into the exhaust stream of diesel vehicles to reduce harmful nitrogen oxide (NOx) emissions. The AdBlue sensor monitors the level and quality of the AdBlue fluid in the vehicle's tank.
