FAQ

Q1: What is this NOx sensor used for?

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

Q2: Are 5WK97103 and 5WK97103A the same part?

A2: Yes.

• 5WK97103 = base Continental sensor reference
• 5WK97103A = updated OEM version
• A2C97451500-01 = cross OEM reference
  They all refer to the same Cummins-compatible NOx sensor.

Q3: Where is this sensor installed?

A3: It is installed in the exhaust aftertreatment system, typically as SCR inlet or outlet NOx sensor depending on truck configuration.

Q4: Which engines use this sensor?

A4: Mainly Cummins EPA10 / Euro 5 / Euro 6 diesel engines used in heavy-duty commercial trucks.

Q5: What are common failure symptoms?

A5:

• Check engine light (MIL)
• SCR / AdBlue system fault
• NOx signal or communication error
• Engine derate / limp mode
