FAQ

Q1: Are 5WK96684A and 68067521AA the same sensor?
A1: Yes. 68067521AA is the Mopar OEM number, and 5WK96684A 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 equipped with the 6.7L Cummins diesel engine (2011–2012) with SCR emissions systems.

Q3: Is this inlet or outlet sensor?
A3: This 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 and sends data to the ECU to control AdBlue dosing and reduce emissions.
