Toyota Hilux

Work-use reality: DPF/soot loading, EGR flow faults, and downtime-friendly checks.

What to expect

Idle time and light-load driving increases soot: DPF faults are often usage + inhibitor combined.
Split pressure sensor hoses and sensor drift cause repeated “DPF” faults without a blocked filter.
EGR restrictions increase soot production and can sit underneath repeat P2002 events.

Tip: Include make/model/year/engine and what changed recently (battery, service, fuel, long idle, short trips). That’s where the diagnosis lives.
