FAQ

Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide levels in exhaust gases before the SCR catalyst to help control DEF dosing and emission performance.

Q2: Where is this sensor installed?
A2: It is installed in the inlet (pre-SCR) position of the exhaust aftertreatment system.

Q3: Is this a 12V sensor?
A3: Yes, it is typically designed for 12V heavy-duty diesel aftertreatment systems.

Q4: Is part number matching required?
A4: Yes, exact OEM part number matching is required because inlet and outlet sensors are not interchangeable.

Q5: What are common failure symptoms?
A5: Engine warning light, SCR efficiency faults, NOx sensor codes, or engine derate/limp mode.
