Genuine Cummins Pressure Temperature Sensor 5569818F

A: Sensor 5569818F (base part number 5569818) is designed for Cummins ISB, QSB, B3.9, B5.9, ISF2.8, and ISF3.8 series diesel engines. It is widely applied in medium & light-duty commercial trucks, buses, construction machinery (excavators, loaders), and diesel generator sets.

A: This dual-function sensor continuously monitors intake manifold air pressure and temperature simultaneously. It feeds precise real-time data back to the ECM (Engine Control Module), enabling optimal fuel injection, improving combustion efficiency, and ensuring compliance with emissions standards.

A: Yes, 5569818F replaces or cross-references with several Cummins sensor part numbers, including 2897332 and 4921850 depending on the ECM configuration and application year. To ensure 100% fitment, please verify your engine serial number (ESN) or part number on your original sensor with our team before ordering.

A: Common symptoms of a faulty intake sensor include:

Check Engine Light (MIL) illuminated with active fault codes.

Lack of engine power, sluggish acceleration, or black exhaust smoke.

Rough idling and unstable fuel efficiency caused by incorrect air-fuel ratio calculations.

A: As sensitive electronic components, 100% of our sensors undergo strict factory testing-including pressure calibration, temperature cycle testing, and signal accuracy checks. We offer both Genuine Cummins sensors and High-Precision OEM-standard aftermarket replacements backed by a 6–12 month warranty.
