My Toyota Hiace has an acceleration failure

My Toyota Hiace has a failure the Open and low acceleration and I don't know what they told me that I could be the Turbo Pressure sensor but I want to be sure and I don't have a SERCA scanner, that I fail to try this sensor is the 5L-E 3.0 Model 2006 Diesel engine, can someone help me ????

Hello, because most cases is the absolute pressure sensor, or an empty leak, so the computer cannot correctly establish the minimum march, I have no exact information, but you can lower the diagnostic procedures from the network to review your empty system, I hope it helps you something and that you solve it soon ...
