FAQ

Q1: What is this NOx sensor used for?

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

Q2: Are 5WK97105A and 5WK97105 the same part?

A2: Yes.

• 5WK97105A = Continental OEM sensor number
• 5WK97105 = base sensor version
• A2C99851300-01 = supplier/OE cross reference
  They are part of the same Cummins-compatible NOx sensor family.

Q3: Which engines use this sensor?

A3: Mainly Cummins EPA10 SCR diesel engines, commonly found in North American heavy-duty trucks such as Kenworth, Peterbilt, and International models.

Q4: Where is this sensor installed?

A4: It is installed in the exhaust aftertreatment system, typically as SCR inlet or outlet NOx sensor depending on configuration.

Q5: What are common failure symptoms?

A5:

• Check engine light (MIL)
• SCR / AdBlue system fault
• NOx efficiency or signal errors
• Limp mode / reduced engine power
