Hello,

this is my first post to this forum. I red almost everything about problems with my model of car. I have V40 2001 1.9D 85KW car. I have power problem under 2500rpm. No vac leaks. I clean EGR valve last week it was clogged. There is leak on inlet manifold where shut off valve meets it. I will change gasket in few days with Renault one spare because of oil leak behind inlet.

I tested some sensors today and I need to check reading that I have wrote.

N75 resistance: 16.5 ohms
MAF sensor signal to ground : on idle 2.3V and rising to 3.2V with rev up
MAP sensor signal to ground: 1.9V on idle and rising to 2.7 with rev up

Can someone check voltages and resistance on this and other sensors on their cars.
I don't know what other fuel sensors are but there are three sensors on passenger side of engine: I guess this are camshaft, fuel pressure and fuel temp sensors. Can somebody explain usage and test procedures of sensors shown on attached picutre

If someone can check resistance on his injector two leads. And if one can tell how to check IAT (intake air temp) sensor (resistance, voltage ...).
My IAT sensor is one integrated in MAF sensor.

Also, I want to test APP (accelerator pedal position sensor) - all readings of this potentiometers are wellcome.

Vida reference:

Thank you
