Multiple Warnings Illuminated - 2012 2.5i

Hey gang!

Well, last night my son came home and told me there were a bunch of lights illuminated on the gauge cluster on the Leggy. Here's what was going on...

1. Check Engine Light illuminated.

2. Traction Control icon illuminated.

3. "Cruise" indicator slowly flashing.

4. "Brake" indicator flashing (a bit faster than the Cruise indicator).

Took it to Autozone to have the codes read.

To note, with the COVID19 protocols, they give you a device to plug into the OBD II that reads/stores the codes. You take that scanner in and they plug it into their computer and tell you what the code is.

I do the above, take the scanner in and they tell me it's a P0028.

Intake Valve Control Solenoid Circuit Range/Performance (Bank 2)

They tell me the part is a bit over a $100 and they don't have it at the moment. I tell them I'll have to wait a bit because I am currently working on my other car.

Go back out to the car, start it up, the lights are gone.

I go back in and ask them if that scanner automatically clears codes. They say it doesn't without doing a series of button pushes, which I didn't do because I didn't know.

Go to the car, drive it home, no more lights.

Son takes his girlfriend home and comes back and no lights.

Any ideas what caused this code or why it just seemed to clear on its own?

He captured a video and sent it to me so I uploaded it to youtube.

Here's a link.

How often do you change/check the oil level? What oil do you use? If the OCV solenoid is bad/failing its not a tough repair, more messy than anything.

Check the harness for both OCVs on the engine, on the FB25 they are easy to get to. I would start by changing the oil and using a good quality synthetic oil and keep an eye on the issue. Remember you need to keep the oil topped off and changed on a FB engine period, the low oil light isnt really helpful, its more of a "well you are all out of detectable oil about 5 miles ago" light
