Check Engine, VSC and TRAC lights came on. Engine was running fine. I read the codes and this is what came up.
44027

I read Fibber's and others' post regarding P0012 and got scared a little. It's been 10k since I last changed oil so I did that. For the P0100, air filter was really dirty so I changed that too. Cleared the codes and hopefully they don't come back.
Or....... should I be worried?

And also just FYI, any time the check engine light comes on with an indicated code, the VSC and TRAC lights will also come on by design, for some bizarre reason. Maybe to attract attention, but it can be disconcerting if you've never seen it before.

Just an update. It's been a week and the problem has not returned. Changing the oil and the air filter took care of it. I've also decided to decrease my oil change interval to maybe 8k miles because of the van's mileage. But, depending on my workload, that could be every other month. It's ok though.

Looks like i need to revive this post because P0012 Camshaft Position A Timing Over-RetardedBank 1 came back this past weekend. It's running fine so i guess "timing" is not the issue? Based on some info i gathered here and other sites, esp from Fibber post, I've decided to tackle this and replace the intake OCV. I've ordered it from Rockauto along with a set of intake plenum gasket. Any additional input on what else i should look for regarding this would be greatly appreciated. Thanks.

Since my last post 19 days ago, the code has not returned but I decided to tackle this yesterday since i had the OCV valve and i had time. There's no way to get to it without removing the upper intake plenum. In the process of removing all these parts, i broke the brittle PCV hose. It took about 2 hours taking my time not to brake anymore parts. I also changed the oil and rotated the tires. I decided to check the front ABS speed sensors because I'm still getting P0500 Vehicle Speed Sensor Circuit Malfunction. Both sensors were measuring in the 1100-1200 ohms and producing similar voltage readings when i spin the hub. Next to check i guess on that issue are the rear sensors.
After i got everything back together, drove to Carquest which is less than 3 miles away to get a 2ft long hose and on my way back home, CEL light came on. I'm thinking what now. Read the code which were P0171, P0174, P0201 and C3101.
P0171 and 0174 I'm almost positive were due to the broken PCV hose so i was relieved.
P0201 is showing Injector Circuit Malfunction Cylinder 1. There's enough room there to put a mechanic's stethoscope and i could hear them clicking pretty good so i don't know what happened there.
C3101 anybody have anything on this?
I've driven it 60 plus miles this morning and CEL light did not come on. She's running really smooth so i hope i don't get P0012 anymore.
