GPD 1815188 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815188 is a direct-fit aftermarket Nitrogen Oxide (NOx) sensor engineered to meet or exceed OEM fit, form, and function. Designed for diesel-powered vehicles equipped with SCR (Selective Catalytic Reduction) exhaust aftertreatment systems, this sensor provides accurate real-time measurement of nitrogen oxide concentrations in the exhaust stream.

The NOx sensor communicates live emissions data to the engine control unit (ECU), enabling the system to precisely regulate DEF (Diesel Exhaust Fluid) injection and optimize SCR catalyst performance. A failed or degraded NOx sensor can trigger diagnostic trouble codes (DTCs), cause poor fuel economy, and result in emissions non-compliance.

Key Features:

• Direct-fit replacement — no modifications required
• Designed to meet or exceed OEM specifications
• Durability tested on every new design
• Ensures accurate NOx measurement for proper emissions system operation
• Helps prevent emissions-related diagnostic trouble codes (DTCs)
• California Proposition 65 Warning applies — see P65Warnings.ca.gov
