I definitely understand trying to rule out every possibility. I don't know if your scan tool can access this, but there's a data group called system protection data that has historic things stored, like the highest fuel temperature logged. If this temp is over 200f, it's a good sign that the...

P204F is not related to a regen problem. That suggests a problem with DEF/SCR. The scanner must be able to talk to the DCU to have any chance of fixing it.

The SCV is asking for maximum fuel pressure but the pump cannot keep up with the demand. To find out if it's a problem with the fuel supply to the pump, disconnect the banjo bolt and line from the supply port, look inside the port for debris, and if clean, connect a test banjo line directly to...

The 2014 is the last year of the burner system, and it's got a couple other technical things that make that year a little unique. The burner system isn't perfect, and to properly fix it he'll need software that can talk to the different modules. The Cummins engine has some pros and cons...

The ABS light being on causes the torque converter to unlock and it'll shift weird (and can cause the transmission to overheat) Have the ABS light looked into soon.

Start a new thread, describing your problem the best you can.

Is the ABS light on? Is the exhaust brake on? Either will keep cruise from working.

It's a Mercedes with a Freightliner badge. For Sprinter anything I visit www.sprinter-source.com.

Check the ground strap between engine and frame. Driver's side.

Ambient temps that low will pull a lot of heat out of the engine, so the gauge dropping isn't a surprise.

You're going to need a belt, and you need to inspect that sensor and see if the wiring or connector is damaged at all.

In my experience, most of the problems with this sensor are caused by people, in one way or the other, or by shredded belts.

It's on the right (passengers side) of the engine, towards the front, right under where the coolant hoses connect.

The OP never replied, so I don't know what happened. Describe what your truck has been doing. What have you checked?

To connect to the engine ECU, VCS, BCU or DCU, you'd connect your scan tool to the 16 pin diagnostic connector. To connect to the TCM or ABS, you'd connect to the 9 pin connector. If it still won't connect, your mechanic should check the TCM connector for battery power, ignition power, grounds...
