The 2010 Toyota Hiace has a EGR (exhaust gas recirculation) systems installed from the factory. They can become problematic after buildup of carbon on the valve or failure of its internal control system that operates the valve.

Our team at Alt Tune have the ability to command the EGR valve to be closed at all times and also remove its fault codes so the entire EGR system including the EGR cooler can be removed. EGR coolers often develop leaks and can be costly to remove.

 

Common EGR related codes we can fix are below.

P0400 Exhaust Gas Recirculation Flow Malfunction.
P0401 Exhaust Gas Recirculation Flow Insufficient Detected.
P0402 Exhaust Gas Recirculation Flow Excessive Detected.
P0403 Exhaust Gas Recirculation Circuit Malfunction.
P0404 Exhaust Gas Recirculation Circuit Range/Performance.
P0405 Exhaust Gas Recirculation Sensor A Circuit Low.
P0406 Exhaust Gas Recirculation Sensor A Circuit High.
P0407 Exhaust Gas Recirculation Sensor B Circuit Low.
P0408 Exhaust Gas Recirculation Sensor B Circuit High.
P0409 Exhaust Gas Recirculation Sensor “A” Circuit.
