The MAF-031 is a mass air flow (MAF) sensor designed as a direct replacement for petrol and diesel applications across Citroen, Peugeot, Fiat, and Lancia vehicles spanning model years 1998 to 2011. The sensor measures the volume and density of air entering the engine, providing the engine management system with the data it requires to calculate accurate fuelling and maintain correct combustion. With 92 verified vehicle applications across four manufacturers, MAF-031 offers broad cross-make coverage from a single part number.
The MAF-031 is supported by an extensive list of OE cross-references, confirming fitment compatibility with references from Citroen (9629471080, 1920 7S, 1920.7S), Fiat (9629471080), Lancia (9629471080), Hella (8ET 009 142-101), Lucas (FDM658), Magneti Marelli (213719623010), Cambiare (VE700103), Fuel Parts (EAM037-M, MAFS013, MAFS013-M), Hoffer (7516026), Meat and Doria (86026), Metzger (0891011), and Mobiletron (MA-B041), including references from Bremi, ERA, Mapco, Herth and Buss, and JP Group among 48 total cross-references.
Verified fitment includes applications such as the Citroen Berlingo (MF) 1.9 D WJY/WJZ (DW8B) from April 1999, the Citroen Berlingo (MF) 2.0 HDi 90 RHY (DW10TD) from February 2002, the Citroen Berlingo Box 1.9 D 70 4WD WJZ (DW8B) from July 1998, and the Citroen Dispatch (U6U) 1.9 D 70 WJZ (DW8) from April 1998. Full fitment coverage extends across Citroen (40 applications), Peugeot (37 applications), Fiat (14 applications), and Lancia (1 application).
