What is Secondary Air Pump (SAP) Diagnostics?
Secondary Air Pump (SAP) Diagnostics is a core petrol emissions concept in modern engine management: Cold-start air pump injecting fresh oxygen into exhaust ports; calibration removes pump relay and flow plausibility faults. Within Softechpro Solutions v2.0.6 (native Windows 10/11, macOS & B2B REST API), supported petrol emissions structures are identified automatically across 4,973+ 12V Car/Van ECUs and 446+ 24V Heavy-Duty Truck & Tractor controllers with integrated block checksum calculation.
