Just got this code on the way home from a drive. Stopped at autozone and they read it. The kid asked if the oil was just changed and I said yes it was a week ago. He then asked what kind of oil was used and where I got it changed. Said I did it myself, full synthetic and 5W-30 as it calls for.

He said it's more than likely it's dirty screens in the engine variable timing sensor and it may clear itself or need a new sensor.

Anyone else think that's the problem? Seems to run fine yet. If it is more than likely the problem how difficult is that sensor to change?

Thanks

The P0014 code means the Bank1 exhaust timing is being reported more advanced than the ECM is commanding.

This could be several things. The VVT could be sticking so it could actually be more advanced or the sensor could be out of whack or the wiring to the oil control valve could be damaged, or the ECM could be damaged.

Shotgunning this could get very very very expensive. You need to take a look at the service manuals and service bulletins then troubleshoot it to narrow it down.

Are you using the GM/AC-Delco oil filters and Dexos rated oil? The VVT system runs off oil pressure. Dexos rated oil is on the shelf at WalMart from several brands and it's no more expensive than the stuff that's not rated... so it's not worth buying the stuff that ain't.
Normally I wouldn't get GM oil filters but on the 3.6L I run the GM filter. With this problem I'd at least look up the bypass valving and media specs to make sure the filter you're using matches the GM filter specs exactly.

Being the untrusting sort I just change my oil at 5,000 mile intervals and re-set the oil life monitor. That's always been well before the oil life monitor gets snotty about it. I figure GM doesn't have a vested interest in my vehicle lasting longer than the end of the warranty. I don't have sludge problems in my LS and 3.6L engines.

Thanks. I did use Castrol edge doxos oil 5W-30 and and a stp extended life filter. The filter I took off was a white generic no name that I could find.

I did pull the battery cable to let the light go out. It hasn't come back on yet. Maybe not a good idea?

There was a lot of discussion on the oil filter on the lfx engines. Factory sent a lot of the lfx engines out with the pf48, later on there was a tsb suggesting to use the pf63 and even gm dealers continued doing changes with the wrong filter. I know, our car had several changes done by the dealer with the pf48. The stp filter may not be to the specs, would change it. Agree with hatzie here, run the delco filter.

Well damn it lol. Thanks
So the pf63 is the correct one?
Autozone has a pf63e? That says is for it.

Now I'm completely confused. My manual says PF63. Websites including rock auto and and autozone and Amazon are saying PF64.

So which is it?

I believe both the 63 and 63e meet the proper specs.

Iirc, member/tech Bart mentioned the PF63, PF63E (e-core) and the PF64 were all ok to use with the PF64 being the "latest/greatest". My '12/'13's were purchased in 2013 from Chevy dealers with the PF48 installed, lol. My son's '16 Limited was purchased last year from a Ford dealer with some unknown generic p.o.s. oil filter installed.

Thanks. Will get one of those and change it.

Well after calling GM customer service even they had trouble telling me which filter lol.

Amazon tells me the PF63E doesn't fit my car. GM tells me that's the one I need.

Who would have thought that an oil filter could cause such issues or potentially. Use to be if it was made to and sold to fit your car that was enough. Oh well, live and learn I guess.

Welcome to the club of "WTF??". I've never owned a car where it was so damn hard to tell which oil filter I needed to use.

In the end, if you sitck with ACDelco and use PF63E, you should be fine. Personally, I've read a lot of bad things about the new "E" (aka "e-core") filters and would rather stay away from them - but finding the correct-spec alternate brand isn't easy. So many places will cross-reference to an oil filter with incorrect bypass ratings. Apparently, GM changed the bypass spec a few years after the car came out, which is why you can't trust cross-reference charts - a lot of them still cross-reference to filters with the old bypass spec.

The original PF63 oil filters had a differernt bypass spec than the newer PF63E filters. PF63E have the "new" correct bypass spec. <sigh>

If you do some searches on the forum for PF63, you'll find some interesting posts and debates on all of this.

LMAO club WTF it is!

And yes I had read about the E ahead of buying a filter so was avoiding that one

I have been using the Mobil1 M1-212 but it has recently changed to a M1-212A which according to Mobil1's web site is equivalent to the PF63.
Anyone know if the M1-212A is the one I should be using?

From what I've deducted the PF63E or equivalent to that one is the correct one.

Got the "correct" filter on today. PF63E

The light hasn't come back on since I pulled the battery cable before and hope it doesn't. At least the filter is now the recommended one by GM.
