Hi,
I cannot find the location of the fuel injection pressure sensor (ac delco 2134420} I am getting a P0090 code and
the car has a new ZZp fuel pump and a new in tank fuel pump.
Thanks for any help.

 

#2 on the diagram. GM p/n 12621292

 

Thank you!!!
If I am reading the diagram right the sensor is near the coolant container side.

 

Yes, that is correct.

 

Ok , I was just at the car, it looks like it is possible to remove it by reaching
from below the car when it is on ramps. Has it been done this way?
Thanks

 

The Haynes manual doesn't indicate that anything has to be removed to get to it.

I did mine with the engine out of the car, so I don't really know. I just looked, maybe just removing the radiator hose would give easy access. I think I wouldn't want to do it from below.

 

That’s it on the left, at the end of the fuel rail you can see the harness connector

 

Thanks for the picture and info, the sensor arrives tomorrow and I will
get to it this weekend,

 

What is the part number for #10 on the first diagram?

 

It’s for an LNF turbo charged 2.0 direct injection engine, not applicable to your 2006 engine
