Safe mode

[bfore]

I have a 2005 hillux 4x4 diesel dual cab , 165000km on clock , went away the other week and after 3hrs the engine wouldn't rev over about 2500rpm, and orange engine light come on ,(Safe mode)  couldn't stop  so i kept driving another half hour until I got to my destination , So temperature gauge ok , water level little bit low, but not too low spent , so i release the screw on top of radiator , to let pressure out , then spent the day riding the motor bikes, then had to drive half hour, car didn't miss a beat! Next morning drove half hour , than rode moto again , packed up a and left to go home (340km drive) after about 1 hour the same thing happened (engine wouldn't rev over about 2500rpm, and orange engine light come on) So I pulled over , turn car off and i release the screw on top of radiator , to let pressure out, Car went fine again, Then it happen again after another hour and half!

So I had a mechanic plug the computer in and 3 faults come up something about manifold?? Took the car to toyota dealer but codes were clear?

Any info would be great?

Unless you have the exact codes it will be hard to diagnose.
