Thanks for the prompt response.
I dont think there is a fuel pressure sensor I may be wrong How can I check this is there any simple steps to check using ODB or techstream ? |

Just to let you know it does starts without any problems runs but acceleration is poor like there seem to be delay in press in gas pedal and acceleration it self.

You're a little vague in what you are calling a delay in acceleration. If the Verso is like the Yaris, throttle response is electronically controlled vs cable controlled. The throttle response in electronic systems experiences a delay vs immediate in cable controlled systems. Very common complaint here on YW when it comes to throttle response in this vehicle.

Thanks for the response, what i meant was it has slow acceleration, I thought it was due to dirty throttle body. I note specially on round abouts I have uploaded the ODB data in the link.Verso S is similar to yaris same engine 1NRFE.
