FAQ

Q1: Are 68067521AA and 5WK96684 the same sensor?
A1: Yes. 68067521AA is the Mopar OEM part number, and 5WK96684 is the Continental NOx sensor reference used in RAM 6.7L SCR systems.

Q2: What vehicles use this sensor?
A2: It is used on RAM 2500, 3500, 4500, and 5500 trucks with the 6.7L Cummins diesel engine (2011–2012) equipped with SCR emissions systems.

Q3: Is this inlet or outlet sensor?
A3: This specific part is typically the upstream (inlet) NOx sensor, mounted before the SCR catalyst.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases before the SCR system and sends data to the ECU to control AdBlue dosing and emissions reduction efficiency.
