    Just wanted to post this so others can compare if need be. I have right at 280K on the truck and the other day had a check engine light come on.

    Ended up dead heading home from Texas because of #### rates and that light made me a little worried. But the rates was the main issue. Took to shop this weekend and had them figure it out. Was putting a fault code out
    SPN-4334 J1939 2 Aftertreatment 1 Diesel Exhaust Fluid Doser 1 Absolute Pressure

    Shop got it all fixed this morning and replaced the DPF Pump. All is good afterwords but might help someone else out later down the road if this comes up on your Volvo.

    Both off mine have bad ground issues, have run grounds direct from battery to different modules to fix.
     
    Siinman Thanks this.

    @Siinman, not to be picky but do you mean DEF pump?
     
    Siinman and Diesel Dave Thank this.

    Do you mean the sending unit inside the DEF tank ?

    Ha Ha Yeah it is the DEF pump. Wrote that and did not even see I had a Typo. Thanks for the correction.

    I might have a similar issue going on. I noticed the last few weeks or so that my inside light when opening door does not turn on right away. Takes 10-30 seconds sometimes. Use to turn on right away or within a couple seconds. Might be a grounding issue maybe? What all did you see causing problems on your issue?

    Volvo says everything is fine. LOL
    I just ran a ground wire direct from the battery to the cab. Only need about 10" wire, there is a bracket hanging down from the cab right above the battery
    just grounded to that.
    If you have dash problems, pull F53 & F54 fuse, wait a couple of minutes and re-install. Volvo's solution to that. LOL
