ENG 3790
New Holland ENG 3790:
Check the cause
Inspect the DPF differential pressure sensor and physical hoses for blockages (soot buildup), melting, cracks, or disconnected lines
Check the wiring harness and connectors for the differential pressure sensor for corrosion, moisture, or crushed wiring looms that can cause false 'Max' readings
Use a diagnostic tool to read the current soot load values and check when the last successful regeneration occurred
Check for accompanying codes related to the EGR system or turbocharger (a malfunctioning EGR valve increases soot production and rapidly clogs the DPF)
