Volvo d13 engine fault code

I am having the same issues. How did you fix it and is it ok to drive ?

 

3471 is after treatment fuel pressure control actuator. FMI 14 is special instructions.. Fuel pressure too high for 7th inj. Most likely cause is is fuel shutoff control valve leaking air. Will not regen.

 

I've been fighting with this code for 3 years, your truck should be fine, it will probably go away on its own, then come back on. Then off. Then on. Most common place air leaks is on the driver's side of the engine behind the frame there is an air line T split and you follow the little air line to the valve on the side of the motor, often that t split leaks

 

I have a 2011 Volvo d13 that is coding out 3471 fmi 14. I have changed the fuel solenoid out and sensors also along with new fuel lines for the 7th inj it will go into regen for one min and then shut it down from regen and then the code will pop up a y suggestions on what the problem could be any help will be appreciated thank you

 

Check all connectors for moister! .. if you found one dry him out and put i little amount of Electronic Grease in...
a lot of the DEF/NOx probs are bad connections!
in the shop they open the connector .. it drys in the time they change a part ..
some weeks/days later same prob!
thats a prob that the first def(adblue) trucks have in europ after they change the type of connector (better sealed ones) no probs on that.

 

I'm personally getting a couple different codes. One is SPN 4811 FMI 2 and the second is MID 144 PSID 230 FMI 5. The second one came up before but then it went off a few days later and now it's back again. This is the first time I've seen the first code. Are either of these going to leave me sitting on the side of the road?
