🔌 Function

Reads the oxides of nitrogen in the exhaust before the catalyst, giving the control system the baseline it needs to set how much reagent to dose.

⚠️ Common Signs of Failure

• Reduced power mode entered by the control system
• Fault stored against the NOx sensor or its heater
• Reagent use climbing or falling away from normal

🛠️ Service Notes

• Confirm the position and the lead length before fitting - post-SCR sensor 23494641 has a 600 mm lead and the two must not be interchanged
