Toyota RAV4

Load-related behaviour, diesel DPF recurrence and petrol catalyst monitoring patterns.

What to expect

Diesel models often show DPF/EGR recurrence when used for short trips or light load driving.
P2002 is usually an inhibitor problem (coolant temp, airflow, EGR) rather than “DPF is done”.
On petrol models, P0420 is often preceded by trim or misfire issues.

Typical OBD2 codes on this platform

P2002

DPF efficiency: log the inhibitor.

P0401

EGR flow insufficient: prove it with data.

P0420

Catalyst efficiency: upstream checks.

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