Tmap sensor voltage 0 (code p0107) !!!

Hi guys,
I have a problem with my R53. Since I bought it we had to change the engine because it was broken. From the very beginning the car is showing p0107 code and the DSC light is always on. I have tested both sensors to see which one is faulty and seen that on the TMAP sensor the signal voltage is always 0V. I decided to buy a new sensor and instantly when I put it in the voltage was still 0V. Otherwise the car is running a little rich and starts to misfire at a constant speed on the highway. You can sometimes smell gasoline too. Please help because I am losing my mind over this car.

That you replaced the sensor and it still reads 0V suggests to me a wiring problem. If the P0107 code appeared *after* the engine swap that raises the possibility of wiring damage during the swap.

I understand what you mean, but when I checked it with a multimeter it doesnt seem logical because the input voltage is 5V like it should be, ground is also connected, it just doesnt show anything on the signal pin.
Thanks for anyones tips.
Have a great one
