Hi,
I had ECU remapping & a new 3" exhaust system put on my 2008 Toyota Prado Diesel in July 2016. In October we went on a 3 week trip with our 2011 Supreme pop top caravan. The Prado was going well & the extra power was worth the upgrade, until the 2nd last day when the engine light came on while under load, going up a steep hill. I drove approx. 10km to our next stop without any problems. When I started the vehicle up in the morning the light was off. When I got home I took it to a mechanic & the fault code was0046 : "Turbo/Super Charger Boost Control Solenoid Circuit Range/Performance". My mechanic said it could be a one off thing or it could have something to do with the Solenoid/Stepper Motor on the Turbo. It hadn't come on again until last week when we took off in our caravan again. Coming on, on steep hills under full load. I took it back to my mechanic, who had a used Solenoid/Stepper Motor which he put on, but the engine light still came on towing the caravan up steep hills under full load. The light was off the next day when I started the Prado up. We are starting to think it might be something to do with the ECU remapping. Can anybody help? Regards, EddiePato.
