The AF sensor is also known as the NOx sensor control unit for emissions control and is used before the catalytic converter (catalytic converter).
Replacing your 759040202 5WK96650 sensor probe with our unit will save you a fortune, solve your NOX problems, and get you back in compliance with environmental emissions laws.
