This is on the 2014 Grand Cherokee 3.6L I used to own, sold it to my aunt and still help maintain it.
It’s had a P06DD CEL off and on since September. If I clear it it’ll come back after a few weeks. I haven’t driven it when the CEL turns on, but my aunt says it’s almost always while either merging on the freeway, or passing someone on the freeway. Not hard acceleration but just moderate. Then she says it usually doesn’t have hardly any power unless you pull over and turn it off and back on again. Seems this code is usually about oil pressure but the digital readout for oil pressure seems good.
I took it to a mechanic shop and they found the oil cooler housing leaking as the 3.6L does and they replaced the oil pressure switch as well. That was a few weeks ago and the CEL just came back on.
Emissions testing is coming up soon and it can’t have a CEL. We also use the Jeep to pull a travel trailer, which makes long trips a little nerve racking, especially if it’s going to lose power on a mountain pass.
My research seems to show sometimes it may be a never-ending battle to fix. It goes into the mechanic on Monday but wanted to give him some extra resources incase anyone else has had this code.
Here’s some screenshots of the data it had when it set the code:
