2012 XC60 Fuel Rail Pressure Sensor replacement

Post by QuietMayhem » Thu Mar 14, 2019 8:35 am

Hi all-

It has been determined that my fuel pressure sensor is bad and needs replacement. I was looking for tips and help as I have never done it before. If anyone can point me in the right direction, it would be much appreciated (such as already existing step by step or video). I have ordered the part, but my understanding is it may help to bleed it prior to etc., and I would like to gather as much information as possible prior to starting. I’m brand new here apologies if I’m not following a certain protocol. Thanks ahead of time for the assistance.

The procedure from Gary is good.

If I were doing the Job I would buy a replacement screw.

Part number 986201

The screw is a Torx drive and there isn't a lot of space to get to it.

If you need to you can remove the entire fuel rail to get access.


One last thought: to depressurize the system you can remove the fuse that powers the fuel pump, is in the fuse box at the passengers feet. Start the car with the fuse removed let it idle and stall, then the rail pressure should be low. (That is what the pictures are showing as far as I can tell)

Good Luck

Paul

Paul's method for first depressurizing the fuel rail is only as good as having the correct fuse box defs for your specific model & year.
(2015 and 2015.5 owners - these are two different MYs).

Your verification of having pulled the correct fuse out is that the engine stalls out shortly after starting it up. This step is essential --
this is when the fuel pressure is being deflated.

I had the misfortune of using the a "2008 - " Electrical Diagrams" generic document -- mine is a 2015.5 XC70. I pulled the wrong fuse.
And I ignored that it didn't stall out the engine as expected. When I pulled off the fuel pressure sensor, it popped like a champaign cork, and my face & clothes got sprayed with a mist of fuel. Fortunately, I had on safety goggles. And, I had waited an hour after driving for the engine to cool off. Don't skip over the "stall out" verification like I did.

Question for "safety-oriented" Volvo engineers -- why did you get rid of the Schraeder valve for depressurizing the fuel rail on these I-6s?
