I have a 2009 2LT with 123,000 miles. Yesterday I went over a bump and the CEL came on. I hadn't noted any problems beforehand. Today I had it checked at Advance Auto and the code came up as P0010. The CEL disappeared afterwards. 3 years ago I had a P0014 code and I changed out only the exhaust solenoid with an OEM GM part. My question is this. How frequently do these require replacing? This time should I replace both solenoids and keep the exhaust one as a spare? Thanks in advance!

I suggest you simply wait until the code returns, if at all. The solenoid may have just had a momentary electrical issue from when you went over that bump. I do suggest you inspect the wiring harness connector to the intake and exhaust cam solenoids just to make sure they’re not loose.

That sounds reasonable to wait Oldblue. But next week I will be heading out for Thanksgiving with probably a 450 miles round trip. Would that be a problem if the CEL comes on again while I'm gone?

I think the exhaust solenoid CEL started with a bump in the road too. But the light came on several times so I ended up changing it out. I'll take the car out tomorrow and drive a bit and see what happens.

You could order one and take it with you or for piece of mind, change it.

Though it could be something else, your P0014 was probably caused by a clogged screen or valve, or a or otherwise malfunctioning valve, in the solenoid valve assembly that controls the exhaust camshaft phaser. This is sometimes a result of neglected oil changes that gum up this and other sensitive parts of the motor.

This time, it’s likely electrical, a problem with the solenoid part of the solenoid valve assembly, and it’s the one that controls the intake camshaft phaser. If so, simply replacing the assembly will fix it. This type of failure seems rather random to me, and there’s no reason to do anything else if it solves the problem. Do not replace both. That would be pointless. (They are different part numbers, BTW.) Using the current GM part is often recommended.

I agree with Oldblue that it might be safe to wait and see if the problem returns. I bought an HHR with this code and drove it home about 200 miles, and then did the replacement. Sometimes the only symptoms are slightly reduced power and fuel economy, and it shouldn’t be a big deal if you go easy.

If the car gives you more trouble than that out of town, a suitable part, if not genuine GM, is available at most parts stores.

Thanks for the suggestions. I'm not sure I can order one and get it before I leave but I will see what I can do. I'll also replace the foam supports for the airbox since those do seem to deteriorate.

I doubt neglected oil changes caused the P0014 code because I keep up to date with them.

The CEL came on again on my trip home from the holiday. It looks like I will be changing out the solenoid. I want to replace the 3 grommets under the air box but am having a hard time with the part numbers. In one thread I read here thre was a discussion about what to use and I'm not sure there was a consensus. Can someone point me in the right direction for a 2009 LT2 2.4L? Thanks

You could also stop by your local GM dealership parts department.

I replaced one and immediately got a code for the other one. Luckily I was in the parking lot of the auto parts store. I don;t think it is pointless to change both at the same time, like brakes and bearings.
