Used in exhaust aftertreatment systems for emissions control.

FAQ
Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide (NOx) levels in the exhaust system and sends data to the ECU to control AdBlue injection and reduce emissions.

Q2: Where is it installed?
A2: It is mounted on the exhaust system, typically before or after the SCR catalytic converter depending on configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue system warnings, NOx sensor fault codes, reduced engine performance, or limp mode activation.

Q4: Is it compatible with all Transit Custom MK2 models?
A4: No, compatibility depends on engine type (2.0 EcoBlue diesel variants), model year, and SCR system setup.
