Porsche NOx (Nitrogen Oxide) Sensor - Vitesco AAA9188880077

Product Information

A NOx (Nitrogen Oxide) sensor monitors the amount of nitrogen oxides (NOx) in a vehicle's exhaust to help the engine control module (ECM) optimize combustion and emissions systems, including EGR and SCR/DEF operation on diesel vehicles. By providing real-time exhaust data, it helps reduce harmful emissions, maintain fuel efficiency, and ensure the vehicle meets emissions standards.

• Check Engine Light (CEL) illuminated
• Reduced engine performance or limp mode
• Increased fuel consumption
• Failed emissions inspection
• DEF system warnings or excessive DEF consumption (diesel)
• SCR catalyst efficiency faults
• Rough idle or hesitation (less common)
• Stored NOx sensor diagnostic trouble codes (DTCs)
