I've had CEL on for a few weeks on my wife's car. I had the codes pulled with an OBDII scanner.
# P0191 Fuel Rail Pressure Sensor Circuit Range/Performance
# P0192 Fuel Rail Pressure Sensor Circuit Low Input

From reading, I understand Volvo also has it's own codes, also. Will this method work to get them:

If you whant to read the dtc code put you key in the 2 position, press the reset odometer button for about 30 seconde and the code should appear on the info tool box,

Re: Fuel Rail Pressure Sensor (pmcintyre)

No, that will only show if trouble code exits. It doesn't even tell you what the codes are.

I forgot to ask about the pressure sensor.

Anythoughts on the OBDII codes-does this look like a bad pressure sensor? From what I can tell, this is an 'easy' repair if one is so inclined.

Re: (tmtalpey)

I bought a sensor from boston volvo, replaced it and the CEL is off.
I saved myself a day it would take for the trip to the dealer and the labor charges.
thanks, tmtalpey

Re: (volvoNB)

I just diag'd one about an hour ago actually. Very easy to replace so no need for a DIY. Its on the left side of the rail looking at it from the front of the car.

Remove the cam cover with the two T30 torx screws
Make sure and bleed the fuel pressure if you can prior to removing the sensor
Remove the connector off the sensor
Remove the T25 screw that holds it to the rail
Pop off the sensor and replace with the new

Its black in case you cant find it http://********************/smile/emthup.gif

Sorry, I'll try to take pictures tonight.
Forcefed has the procedure right.
I don't know how to bleed the pressure, but be sure to use a rag, and slowly pull the sensor off. It is under pressure, fuel will spray out and force the sensor off the rail like a champagne cork.
