Hello,

I am experiencing the check engine code P1101 on my 2017 Malibu 1.5 LT.

I have already attempted the following troubleshooting steps:

1. Changed the air filter.

2. Replaced the MAF sensor.

3. Cleaned the throttle body.

4. Replaced the PCV valves.

The code persists, and I would appreciate any assistance or guidance you could offer to continue troubleshooting this issue.

Extra information:

- MAF sensor 2.4 g/s

- I noticed air coming out from the dipstick oil whole

I am requesting assistance with a Chevy Malibu 2017 (68,000 miles) that is displaying a P1101 code.

I have already attempted the following troubleshooting steps:

1. Changed the air filter.

2. Cleaned the throttle body.

3. Replaced the three PCV valves located on the top valve cover.

4. Replaced the MAF sensor.

The code is still there, and I'm not sure what else I can do.

When I remove the oil dipstick, I observe steam and air escaping from it. I am unsure if this is a normal occurrence.
