About the Hilux
The iconic HiLux first made its debut in 1968 and has remained one of the highest-selling pickup truck models to this day. During its long run on the market, there have been a total of eight generations, with the latest iteration being released in 2015.
Because of the HiLux’s huge impact on the pickup truck class, it has been the inspiration to many other trucks out there today. The most notable rivals for it include the Ford Ranger, Isuzu D-Max, and Volkswagen Amarok.
The model has received huge praise for being possibly the most reliable vehicle on the road today. Still, all vehicles are susceptible to problems here and there.
One of the most commonly reported fault codes for the model is P0046, which indicates a problem with the control circuit of the forced induction system, be it a turbocharger or supercharger.
Another fairly common code is P0047, which similarly indicates a fault in the control circuit for the turbocharger or supercharger.
These can be very serious codes that can put your HiLux into limp mode, meaning they need to be fixed very quickly. Of course, because they are in the forced induction system this means only certain variants can suffer these codes.
Owners have found success in checking the various components in the forced induction system, particularly actuators. Any stuck components like the wastegate can cause this issue. Other issues can include faults in the control circuit like wiring problems.
Another less serious code is P0400, which indicates an exhaust gas recirculation (EGR) flow malfunction.
This can typically be caused by either a faulty dirty or defective EGR valve body and cooler. Some owners have also found that cleaning the airflow meter can clear the code.
