Hi,

Around 1 month ago, I had received a CEL with P0011. I had reset the light and driven the car for a few days with nothing being shown in pending or confirmed (150 - 200 miles) It came back after that (pending) but wouldn’t throw the CEL light. There would be days where I drive to and from work and wouldn’t get the pending code, and other days where I would get the code on the drive there or from work but then on the next startup (Few hours later) the code would wipe itself. The camshaft and sprockets have all been replaced around 18k-20k miles ago. Along with the Oil and VVT being replaced last week to see if the code would stop appearing.

After some testing, I noticed that the code will only appear if I go on a drive that involves a lot of stop & go traffic (or stop and go in general) , oil temps get to about 200F-215F and if I drive the car and don’t experience that kind of traffic, then the code won’t appear at all(temps also wont go above 200).
Since I’ve replaced the VVT and Oil, I’m starting to wonder if there might be an issue with oil pressure when the oil starts getting above 200F. Another thing I’ve noticed is that if I drive to where the car oil temp is around 200F and then I shut the car off and then start it about 10-15 minutes later when its still hot, when I shift into drive, the oil pressure light will flicker for about 2 seconds, and same goes for reverse. The pending code will also appear and if it had appeared on the drive previously, then the CEL will be thrown. This issue with my oil pressure will NOT occur with oil temps below 180F. I don’t believe the oil pump is much older than the new camshafts either, but I could re-check. Right now, I’m just trying to think of any possibilities to what this could be.

I’ve ran 0w-20 for 2 years (between driving in CT and VT) and within the past 3-4 months have been driving more spiritly ever since I put my catback on. I’ve heard that some people also use 5w-30 when it comes to oil and I’ve been wondering if switching to this might show an improvement.

I appreciate anyone taking the time out of their day to offer advice on what this possibly might be.
