has anybody seen this??? check engine light comes on....code says Cam button sensor...buy one from dealer and replace...reset light...comes right back on with the same code....try different sensor from dealer thinking I may have a bad one...light stays on....now I am getting a weird stumble at idle....any ideas???

 

Without posting up the actual code number it's hard to say, but it sounds like you replaced the wrong part(s).

I don't think I've ever heard the term cam button sensor on the HHR. I'm thinking maybe you've got an actuator solenoid problem.

Post up that actual code number and we'll try to point you in the right direction.
And posting up the year model, engine size and mileage always helps.

 

x2 - come on people - we really do want to help get you back on the road ASAP, but you have to help us out with providing ALL relevant information. Post the code(s) and we'll see what advice we can offer to help you out.

 

There is no code "Cam button sensor" in fact, the codes are numbers not descriptions. I.E.: P0013.

 

Hello HHR16,

I understand that you have already purchased parts from your local dealership to resolve this issue yourself. As a customer service representative, I'm not able to provide much in the way of do-it-yourself information, so I'm glad to see forum members are beginning to step in with feedback. If you have any lingering concerns, please contact me via private message.
