Sure!, previously if would come out of Tire Jack mode if you started the car. on Rev "D" It does no longer, The light says ORAII, even though you're not - I have not tried to put it in "D" and just drive to see if it will revert back then (with the new flash)

Re: New ECM/TCM flash coming out

I've had the P20EE code three times already in 8,000 miles.

Asked my dealer to order the new parts. Runs ok otherwise.

Very frustrated because the remote start won't work while the CEL is on.

How do you start a star case with Chrysler? I also have the decreased mpg after the trans update.

Re: New ECM/TCM flash coming out

I have been using my OBDII scanner to erase the codes so my remote start will work. I told my service guy that while I was waiting for the Cat to come in, when the code came back, I was going to erase it. He said to just keep track of the code and to write down if any other codes(other than the P20EE) showed up.

I bought a cheap pocket scanner from Autozone. Like $50. It just plugs into the port under the dash near your left knee.

Re: New ECM/TCM flash coming out

Just had our '14 in for the two recalls. No issues until now. Got a check engine light the same day we got it back from the dealer. We now have the dreaded P20EE-00. Dealer says we have to bring it back next week to install a new O2 sensor. Is does not sound like this will fix the issue from what I have read here. What is the TSB# that states they need to replace the cat converter. This really sucks because we had almost 20k miles on it with zero issues.

The P20EE TSB is 18-045-14. The link to the service bulletins is below. You can download the PDF file.

Don't panic. The P20EE doesn't prevent you from driving. In fact, the error will likely go away. My P20EE has been gone for 2,400 miles.

Re: New ECM/TCM flash coming out

Did yours go away on it's own or did they have to replace the cat?
Thanks for the TSB link.

My P20EE went away due to driving a couple hundred miles after clearing the error with a OBDII. I still have the original CAT.
