2008 V70 P0190 Fuel Pressure Sensor

Post by martyrl » Mon Jun 02, 2014 5:28 pm

Was getting P0190 & car was occasionally cutting out. Replacing the fuel pressure sensor was an easy fix.
Original part # Volvo 30756097 Bosch 0261230110. Google search brought up a number of 'reasonable' priced alternatives. See http://forums.swedespeed.com/showthread ... -and-parts and http://forums.swedespeed.com/showthread ... -T5-engine

I purchase Napa 2-260017 for $89.00

1) Removed fuel pump fuse ( #22 under glove compartment)
2) Turned over engine a few times to reduce pressure in system
3) Detached battery & covered terminal
4) Remove engine cover
5) FPS is on right side of fuel rail. Place rags under sensor to catch excess gas
6) Usef torx 25 key to remove bolt holding sensor. Hard to see & tight fit. This was the hardest part - getting the key into the small space and snug into the bolt.
7) remove sensor and detach wiring clip
8) reverse steps to install.
9) Enable ignition w/o starting & confirm no pressure leaks
10) Start car & confirm no pressure leaks.

Took about 45 minutes & saved about $400 over dealer quote.

Also found it interesting that there was a recall in 2004 for the same FPS (same part #). When I asked the dealer about it they replied that it was probably a 'bad batch' of sensors and the recall only applied to 2004 model years (or something - it is Recall 181). I find it strange that there would be a recall for a particular part from 2004 but they would continue to use the same Bosch \ Volvo part number.

I just did this on a 2008 XC70 with the 3.2 engine.

For the life of me, I could not get a torx bit in that ridiculously tiny space, so here is what I did:

1. Remove plastic engine cover
2. Remove 20amp fuel pump fuse from fuse box under glove box
3. Start engine to relieve fuel pressure (it died instantly)
4. Unbolt 3 x 8mm bolts securing the fuel rail.
5. Carefully remove 4 or 5 of the injector electrical connectors.
6. Gently wiggle the right side of the fuel rail and gently pull upwards. *note, prior to doing this, vacuum or blow out with compressed air all the loose junk that has settled in the area; you don't this going into the engine.
7. Pull the right side of the fuel rail up enough to access the sensor torx bolt, maybe only 2" or so.
8. Use your torx 25 bit to unbolt the sensor and carefully remove the sensor. It would be a good idea to have a rag underneath as a few ounces of fuel will poor out.
9. Put some fuel on the new seal of the new sensor and reinstall it.
10. If the bottom of your injector seals have junk on it, CAREFULLY wipe it off with a rag, making sure nothing drops into the engine.
11. Reverse the steps for installation and then test for leaks. Be very careful to not damage the injector connectors.

Took about an hour, taking my time.

Thank you for the explanations. I bought a Kobalt 24pc right angle bit socket (w/25mm Tory included) at Lowe’s for less than $16 that made removing the hex screw easy :D

I used this on mine (2010 S80 T6): MulWark 20pc 1/4 Ultra Low Profile Mini Ratchet Wrench Close Quarters Screwdriver Set with High Torque from Amazon:

It just barely fit but I was able to unscrew it.
