just finishing up a 3k road trip, check engine light popped 5 times.. each time for about 3 key cycles.

I'm still not quite home, but I stopped at a dealership & had them check it out, the only stored code I had was P245A, something to do with EGR system.

He said it was something he'd have to order parts for, so I set up an appointment with home dealership.

7100M on the truck, stock except for intake. No performance/effeciency decrease when code pops, just irritating light

anyone else feelin the P245A blues?

 

I had a P245f a few weeks ago - dealer did a flash for it; the code is for the ash sensor in the DPF. Evidently it was an erroneous code, ergo the flash. Didn't have any affect on mpg or performance that I could tell.

 

Your dealer is not communicating very well.

P245 is egr cooler bypass valve. It's prolly sticking. You are right that it will not affect performance, just emissions.

What is an "ash sensor"? There are oxygen sensors, pressure sensors, and temperature sensors.

 

I had that code come up yesterday. EGR bypass valve stuck. Dealer said keep driving untill parts come in on Monday. By the way hello everyone I'm a newbie to site.

 

You're probably right that it was not communicated clearly; I am assuming that he meant the pressure sensors were indicating an ash accumulation in the DPF - at least that is what was written on the RO. It states that a flash was done for it - haven't had it recurr so far. Sorry if it was confusing.

 

lights been on & off again twice since i posted that first, so irritating

 

Mine just came on tonight...though it may be something to do with the new Airaid I just installed.

 

There is a TSB that applies that requires a software update....p0245 is indeed one of the codes that is covered in this bullitin. I've done about a dozen so far.

 

i had that code last week tech called chrylser and they told him all he had to do was take out the sensor in egr valve and clean it

 

Had same issue. Sometimes would go a week before seeing the light again. Dealer did the reflash and 20 miles later had the light again. Next time they removed the EGR and cleaned it and the temp sensor , that was nearly 3 weeks ago and haven't seen the light since.
My guess is if the EGR is cruded up the reflash won't fix it , you need to have the soot removed from it , mine was loaded with soot. Hopefully the reflash will prevent anymore soot buildup.

 

How long does the reflash take?

 

Does anyone happen to know the TSB number? I got this code yesterday..

 

Dealer replaced my entire egr valve. Is also supposed to mail me a copy of tsb, it was closing time when I was there. Should get it today in the mail.

 

well I got the truck back today & the light came on less than 30 miles later, not sure if its the same code, can't get the display to show me.. sometimes it shows me, sometimes it doesnt...

Dealership said they pulled P245A & P2262, cleaned particulate filter, cleaned EGR system & computer reflash, then sent me on my way

this is so irritating....

I'm getting to the point where I hope it KEEPS messing up so I can lemon law it

 

Got the MIL yesterday with the 245A code for the first time. Truck's 3 weeks old (4300miles). Dealer's reflashing this AM and replacing the EGR cooler. We'll see how it goes.
