62k Miles, Turbo needs replacing

[goldensnubnose]

Sorry to hear that, but something else in that circuit took it out, if it is indeed fried. A full circuit check needs to be done before installing a new PCM.
Possibly & hopefully the original Turbo (Wastegate Actuator) vs something else or the wiring circuit. (Less Labor-Charge)

I would expect the truck to not operate at all if the PCM were 'fried'. I suspect airline tech is on to something -- there is something wrong with a specific part of your harness, a connector, or a related circuit that is causing the PCM to complain.

Yes that seems logical, but I'm just forwarding what the shop said. They told me once they discovered it was an issue with the PCM they stopped the diagnosis because they don't have the tools to work on it. I've called two other shops and both of them said the same thing, they don't have the equipment to work on the truck. I pretty much have to go to a dealer to get this serviced and the last dealer was wrong on their diagnosis and tried to overcharge me. Stuck between a rock and a hard place and I just want the truck gone at this point.

I called around and pretty much every shop is saying they're too busy. One dealer said they were booked out until January. Two dealers aren't even picking up. The dealer I took it to originally said they have availability but then when they tried connecting me to a service rep it just went straight to voicemail. I don't really want to bring it back to them considering their incorrect diagnosis the first time around.

I’m not sure if you’ve figured out the issue or if you’ll see this. I’m not even sure if replacing the turbo called for removal of the EGR valve. I just replaced an EGR valve on one of these and the oxygen sensor and EGR valve connectors are the same and you can get them crossed since they’re right beside one another. I was getting the same issue until I figured out where I screwed up.

Good Catch, yes sometimes you have to pay attention to detail on the harness run, if you pull up the connector pinout, they are both 5 cavities. However, from the diagram pic they are slightly shaped differently.
FYI. The Turbo does not call out for EGR Valve removal but does have you pull the cooler (per the manual anyway) IDK if actually required for Turbo removal. There are normally shortcuts for a crafty tech.

Out of curiosity, what drove you to replace the EGR valve, I have not had any issues with mine. But there is a lengthy thread on the Buck / Surge issues with the Ranger 2.3.
The DPFE sensor being replaced appears to be the Fix, for this No-Code issue, the most widely reported code (if it does code) is P139C.
So, I was just curious if you replaced the EGR valve due to code specific (electronic failure) or drivability (not fully closing / clogged) and what PID parameter was askew.
As there are some members on this forum that replaced the DPFE and No-Help and MANY on this forum that experience the dealer (No-Code, No-Problem, here is your truck back).

I rarely see this and I was moving a little too fast haha typically the connectors will have an offset tab that matches it’s partnering connector.

Im a tech at an auction and I replace parts the other techs recommend in order to fix an issue. Almost every time, it’s a misdiagnosis so I end up having to do intensive diag. I actually ordered a DPFE for it. They’re not gonna pay todisassemble the whole EGR tubing so there still could be an issue. We have to move cars fast so sometimes we will throw a $50 part at the car and see if it fixes it. Our supervisor wants it this way and he eats the cost anyway

The DPFE sensor did in fact clear the code (P139C) and the idle surge/buck issue the truck had. I replaced the sensor this morning and the truck has no drivability issues/CEL.
