Boost Pressure Sensors

Boost pressure (MAP) sensors read intake manifold pressure so the engine control module can fuel the engine correctly; a failing sensor can cause low power or boost-related fault codes. We list ten replacements, all supplied by PAI Industries:

• Caterpillar: PAI 350581 kit for C11, C13 and C15 ACERT; 1611704; 1946723
• Cummins: 4921497 and 3084521
• Detroit Diesel: 23527829 and 23535663
• Mack: PAI FSU-0486 for E7/ASET; 64MT480M
• Navistar: 1846481C92 MAP sensor kit

Most listings are titled by the OEM number they replace. Match that number to the one on your sensor rather than going by engine alone, since one engine family can use more than one boost sensor over its production years. Related: air pressure sensors, temperature sensors and turbochargers.
