A lot of work to replace this sensor but if it will fix fuel rail issues! If you are going to replace this, I'd recommend replacing the sensorbon the fuel pump that will save your fuel system is that cp4 fails.

This is the OEM part so it fits exactly like it should and best of all works exactly like it should.The wrench used is the same size so you don’t need to worry about wondering if you need other sizes.It’s a good part, if you need one this one works.
