P245A code

[dave110]

Truck is my dads 09. He's not in good shape health wise so I've been running the truck the last week or two getting it ready to sell. The EGR's been unplugged for a few years and has helped a lot, but I plugged it back in so the CEL would go away before I list it and it did as usual and has been out for a few days. Today I got a CEL for a 245A code, something to do with turbo solenoid voltage. I cleared it and it stayed out for now, but it's only been 15 mi. or so. Any idea what it means and what to look for?

Reminds me again why I refuse to get rid of my 99

P245A is a EGR voltage issue.

Thanks for the link. Plenty of information and possible causes. I'm guessing it's probably sooted up like everything else on a DPF equipped truck. Hopefully get to look over the weekend.

No. It a voltage issue. The ECM is sensing a voltage problem in the EGR circuit. Nothing to do with sooting up. It the fact that the ECM is seeing a voltage out of range. Either shorted to ground or open lead.

I mean the servo is trying to move the butterfly but can't because it's sooted up and needs cleaned therefore causing an over draw. At least that's what I understood some had problems with.

[Mopar1973Man]

ECM doesn't sense current draw. Only voltage.

Hmmm. Reading through the info on the link provided it seems a dirty EGR can stick open and cause the code. Some had success with a simple cleaning which is why I suspect it. Seems this code can be the result of several issues.

Did you ever figure it out 

[dave110]

Not exactly. I just unplugged the stupid thing again and the code and issues went away. I'm still convinced from the reading I did that it was dirty and could not move fully causing the code. At 64k mi. it was on the edge of needing the 67.5k cleaning service anyhow. I'll never know for sure because the truck is gone now along with dad. I told the new owner and it was no big deal to him because the first thing he was planning on was deleting

[Mopar1973Man]

The only thing I can say is either take the time and clean the EGR system or delete it. Personally I would just delete. Most people want to hold on the warranty so that tosses back to cleaning the system out.

Sorry for your loss, and good to hear that you sold the truck and told new owner about it, it sucks buying things and not knowing history. 

[dave110]

Thank You.

Actually, unplugging it worked very well. It did not re-gen nearly as often and picked up about 2 MPG. If the truck would not have been sold I probably would have deleted it at the time of the 67.5K service. I'm pretty sure I had Dad talked into it. No matter now. The young fellow who bought it most likely deleted it all and installed an axle dump with an 8" tip lol.
