AGCO - 4226448M91 - Cylinder Head Temperature Sensor Massey Ferguson

This cylinder head temperature sensor monitors the thermal load of the engine at the cylinder head. It sends a signal to the engine control unit, which adjusts fuel delivery and cooling system operation based on the reading. A failed or drifting sensor can cause incorrect fuel metering, leading to reduced power output or elevated exhaust temperatures. The original AGCO component matches the thread profile and sealing surface of the cylinder head port, ensuring a leak-free installation and correct signal response. When reinstalling, apply a small amount of thread sealant to the sensor threads.
