You can grab them from the dealer - they were ~$75 each here in Canada -
12628348 - Exhaust cam solenoid
12628347 - Intake cam solenoid

One of them was in-stock, the other was delivered the next morning to the dealer - so I gather they are a commonly available part. The code you pull down from the CEL, will tell you which solenoid needs replacing (I replaced both of them as I figured, what the heck if I am gonna tear it apart for one, I'll replace them both).

Good luck

 

I ordered from a website called gmpartsdirect.com using that part number and it was $81 with shipping, hopefully will work. Will post when I get the parts and put them in.

 

Good stuff. Keep us posted.

 

which solenoid is the exhaust? my code p0014 and tc light are on i used a code changer at advance auto to turn them off. i want to do the switch so they stay off. not sure which is exhaust and intake

 

Intake is in the front; exhaust in the rear.

 

thanks for the help, the hard shifting will go away? also the tc lite will go out? when i replace the 2 solenoids?

 

Thank You. Thank You. Thank You. That made my day. I have a much better understanding of the critter now and might save a few hundred on the fix. Good stuff with pictures and instructions.

 

Thanks to Whopper and all who posted on this subject. I paid the dealer to replace the first solenoid then I read all about it here and ordered the other one and fixed it myself. Car runs great and no lights so far! Thanks again for the detailed how to. It really did help.

 

My TC light came on yesterday and was off this morning and on again today leaving work and this time the engine light came on as well.

I know it is time for an oil change (25%), so will have the dealer have a look see for me -- it did seem to run a little rougher and felt like it "pulled" when the gears changed (have an automatic) -- I assume that is not normal. :)

I drove him home from work, 35 miles on the freeway and he seemed as smooth as ever otherwise...I've NEVER had problems in almost 3 years, so am a little concerned (at 32K now).

I'll have them check the solenoid thingy.
Thanks!

Good luck. and yeah sounds like it might be the "solenoid thingy"! :) Hopefully they will be able to retrieve codes that clarify the problem.

Cheers
