    Hello everyone,

    I've tried cleaning the solenoids, and they were a bit clogged, but it hasn't fixed the error and my lacrosse runs a bit poorly stuttering.

    I feel like they could have failed, but I'm not sure how to check. Assuming they're fine it's a failed censor, then. Any tips for determining if a sensor has failed, or not?

    Update: bought and installed a new intake solenoid. Fired it up and it ran like a watch, again. And then the check engine light turned off after I put some gas in a half mile down the road.

    Thank you!

    I kid you not, just ran into this last week with the wifes malibu. 2.0T engine, threw P0010 and P0011 codes. Cleared them and they were fine for about a week, then came back. Went ahead and replaced both intake and exhaust VVT solenoids this weekend. (tested the intake one for continuity and it seemed ok, but the problem has been intermittent so its not surprising it checked ok electrically. I guessing its sticking sporadically). Time will tell, but I'm hoping the new solenoids square it away.

    Glad you got your issue resolved.

    I got the P0010 & P0011 codes with one of our 2.0 Ecotec turbo engines last month. From what I've read, the solenoids can not be cleaned with much success. Therefore, I bought a pair of new solenoids from Amazon for $36.97 and just installed the intake side only since that is P0010/P0011 code. Issue is fixed and codes never returned.

    We see those codes often.
    First step is to check oil level. Those earlier ecotecs are notorious for using oil and not uncommon to see them with those codes and oil level not even touching the stick !

    I almost just did the intake since if the exhaust was malfunctioning it likely wouldve showed a P0013, but since I was already there and read multiple things that once one goes the other often follows, I decided just to do both.

    my issue has been solved!1

    For a customer’s car I also would strongly advise them to have both replaced. Since I was working on my own car I just did one because it’s a very quick job to replace the other one if needed.

    I currently have two cars with the 2.0 liter turbo Ecotecs, and had one other previously, and this is the only issue I can ever remember having with any of them. From my experience they are great little engines that produce great power and fuel economy. Just having my wife’s retuned picked up 99.6 hp at the wheels and it improved the fuel economy by 2 mpg.
