Did you search the forum? There are other threads as well. There may be a recall for the P0420?

2014 ODB code P1063 and P1069

116,000 miles on my 2014 SXT. Recently has been running really rough when starting. Mostly on first start of the day. Have changed plugs and coil packs. 1069 says potential VVT solenoid issue???? Any ideas?

I’m searching threw them now. Thank you. I’ve also already checked for updated recalls and there is none.

I was able to watch the live data for both O2 sensors. The range for the first was bouncing between 0.055-0.075 and it never dropped or acted weird. The second however, would bounce between 0.020 all the way to -0.027. I may just be paranoid at this point but is that normal? Also the CAT temp was all the way up to 800 degrees.

What kind of outdoor temperatures are you dealing with there?? That cat temp seems low in my opinion unless its -30 outside. And I don't believe either O2 sensor should have that much of a swing...maybe found the issue there???

 

[AdrianeWalters]

It’s currently 42 degrees. I didn’t think it was normal either and it’s constantly staying in that range going back and forth. I rather it be the sensor than the catalytic converter anyday. These darts are a special kind of nightmare I know that.

 

[alpinegreenneon]

Be sure to get Mopar or NTK O2 sensors. These engines don't like Bosch sensors.

 

[AdrianeWalters]

I definitely will. Is it possible that a misfire would cause the O2 sensor to read different?

 

[alpinegreenneon]

The misfire could be from the p1069 code. Unburned fuel isn't good for the cat.

 

[AdrianeWalters]

I know I’m worried about that. It’s only cylinder 3 that is misfiring. I’m using ngk plugs but my coils are a set that my neighbor bought for me from Amazon and I found out that he literally searched for $20 coils that would fit and ordered the first one that came up on the list without looking at anything else or even the reviews. When I found this out and researched those coils, the reviews are so horrendous It’s unbelievable.

 

[alpinegreenneon]

The MultiAir is what you should be looking at. It's what controls valve opening and closing. If they're not letting compression happen, there's the cause of the misfire.

 

[AdrianeWalters]

How would I even check the multi air? Right now it’s not a constant Misfire, but it is getting worse. I’ve been scrambling my brain over this car lol.

 

[alpinegreenneon]

There's nothing to check, start looking for a MultiAir brick. Yours has probably got a bad solenoid.
