Avensis and RAV4 diesels. The early 2.2 had head gasket sins; otherwise classic diesel territory: DPF, EGR and injectors at high mileage.
Click a code for the full breakdown: symptoms, causes, and whether you can keep driving.
Diesel Particulate Filter Efficiency Below Threshold
The DPF is not trapping soot as it should - it may be damaged, removed, or overloaded.
Turbocharger Underboost
The turbo is producing less boost pressure than the ECU requests.
EGR Flow Insufficient
The exhaust gas recirculation valve is not flowing enough exhaust back into the intake, usually due to carbon buildup.
Fuel Rail/System Pressure Too Low
Measured fuel pressure is below what the ECU commands - the engine may be starved of fuel under load.
Glow Plug Module Control Circuit (Diesel)
The control circuit of the diesel glow plug module has a fault.
Lost Communication With ECM/PCM
Other modules on the CAN network cannot communicate with the engine control module.
