What happens when a NOx sensor goes bad?

2025-11-24

A faulty NOx sensor can cause:

‌Engine performance issues‌ (reduced power, unstable idling) due to incorrect fuel injection adjustments‌.

‌Increased fuel consumption‌ as the engine control unit fails to optimize combustion‌

‌Failed emissions tests‌ from unmonitored nitrogen oxide levels, potentially violating environmental regulations‌

 

  • ‌Illuminated check engine light‌ (DTC codes like P0420/P0421 may appear)‌13
  • ‌Accelerated wear‌ on exhaust after-treatment systems (e.g., SCR catalysts) from prolonged exposure to excessive
  • Immediate replacement is recommended to prevent further damage. Diagnostic tools can confirm sensor faults‌
