Selected Ram 4500 / 5500 chassis cab models

FAQ

Q1: What is this NOx sensor used for?

A1: It measures nitrogen oxide (NOx) in diesel exhaust and sends data to the SCR system to control AdBlue (DEF) injection and reduce emissions.

Q2: Are 68366500AB and 68366500AC the same?

A2: Yes.

  • 68366500AB = original OEM Mopar part number
  • 68366500AC = updated/replacement revision
    They are part of the same NOx sensor family used on Cummins 6.7L SCR systems.

Q3: Where is this sensor installed?

A3: It is installed in the exhaust aftertreatment system, typically as an upstream or downstream NOx sensor depending on configuration (before or after SCR catalyst).

Q4: Which engines use this sensor?

A4: Mainly 6.7L Cummins turbo diesel engines used in Ram 2500 and 3500 heavy-duty trucks.

Q5: What are common failure symptoms?

A5:

  • Check engine light (MIL)
  • SCR/AdBlue system faults
  • NOx sensor efficiency codes (P2200–P2202 range)
  • Limp mode / reduced power
