Description
The PAI Industries 350581 is a boost pressure (MAP) sensor kit for Caterpillar C11, C13, C15, C15 ACERT, and C18 diesel engines, replacing CAT 249-0096 and superseded numbers 248-2165 and 2746718. The sensor reports intake manifold pressure to the ECM for fuel-quantity and turbo-control logic. Kit includes the matching O-ring (PAI 321270 / CAT 0335853) for a complete leak-free install.
Signs You Need a New Boost Pressure Sensor
- Significant power loss or truck won’t build proper boost
- Erratic or fluctuating boost gauge readings
- Check engine light with boost-pressure fault codes (Flashcode 25)
- ECM shows 0 psi boost while a mechanical gauge shows pressure
