From what i can see, this is a code for a faulty injector signal, do you have a misfire or any other codes?

Dear Sir,
I checked but I didn’t get any other code or misfire.
And on idle speed its ok but when we press accelerate paddle on 1500 RPM then check engine light appear on multi information display and that time we got only one DTC P1601

Dear Ahmed,
I recommend to check in technical Toyota repair agent maybe the Injector nozzles are dirty or damaged.because of bad quality or dirty gasoline.
