Dropped hubby at work Thursday morning. Started up HHRbie (he drove the first leg) and the CEL came on. At my first opportunity I had Advanced Auto pull the code. Came back as P0011 and a list of 4 different things as they can get GM specific but not model specific. HHRbie has 133k on him and I want to keep it runnung so the kid can use it as his first car in a couple years.

Any and all answers are appreciated!

Did you try a Search here?

That code is one that has been discussed numerous times and in great detail on this site.
Without having to repeat pages of threads and info, I'll just say at your mileage, it probably needs the actuator solenoids replaced.(not the sensors)

Search result led to this. https://www.chevyhhr.net/forums/how-...13-14-a-28779/

I would advise reading all 47 pages.

Thanks for jumping in there Firemangeorge.

I wonder what the "4 different things" refers to.

firemangeorge

2 different actuators, 2 different sensors ?
(you know how the auto parts people like to wrongly tell folks it's the sensors)

Go with replacing the actuator solenoid, specifically the intake. I did on mine and it runs much better.

Sadly, the OP yelled for "HEELLPP!!!!", then didn't come back.
