Traction control light; hard shift
Hello everyone:) always a pleasure to come visit. Thank you all in advance for helping me out with yet another problem with my 2006 LT. So now this is what my HHR is doing. When I start it, there is no traction control light. If I either let it sit idling, or if I am stopped in traffic for too long, the traction control light comes on. When this happens, the transmission hard shifts. I have to shut the car off and restart. When I restart the car, the traction control light goes out. Then the car runs and drives fine. But man if I let it idle in my driveway for more than 5 minutes that pesky traction control light comes back on. Any ideas? In order for me to keep the traction control light out, I need to keep the car in motion. Very strange phenomena and I have no idea why on Earth this would be going on. Any help would be greatly appreciated :-)

It sounds like a hub problem, but to determine which one you need to use a OBDII code reader that will read more than just the basic engine codes - some suggestions are in the above thread. |

Check the wire to the #1 cylinder coil, if it’s a separate coil.
Your 2006 might have a coil pack and you’ll need to remove the air cleaner box, and the coil pack. How many miles on the spark plugs? What brand plugs are in there? |
It is the p0301 that is setting the traction control and hard shifting.
After you do what Oldblue suggested you need to do a compression and leakdown test. |
Shojay92 - the p0301 error code for the misfire should have lit up the Check Engine light. Did the light not come on during the reported problems?

the plugs are new, Bosch. This is why the traction control light comes on?

Something is wrong here. When I look up shojay's profile he has a 2009 SS. Or am I missing something here?
|
Yeah I am beginning to wonder too - although he may have two HHRs.
No mention of check engine light - which should come on with a p0301 code. and he didn't anwer the question I raised about it. I'm out |
OK, in your 2006 2.4 HHR , it was designed for AC Delco Iridium 41-103 plugs

Yes, I remember he has 2 HHRs.
Agree, it could be the non-ACDelco spark plugs. That's an easy theory to test. |

Go to your "User CP" and set your notifications.
|
When you pull the plugs to do the compression test, double check them for differences between cylinders

Nah it was misfiring before I put the plugs in. Still does it
|
Why not do some diagnostics before throwing money at it? The parts you mention are unlikely to cure a misfire.
switching coils and injectors, compression/leakdown, fuel pressure etc. |

I wish my pockets were that deep. It is a lot cheaper to learn how than to buy useless parts.
How had you intended to change the parts you bought? Switching injectors and coils is the same process as changing them. Any big box auto store should loan a compression kit and a fuel pressure kit. None of that is rocket science. |

You were chasing this misfire 3 months ago(stuck spark plug), Is the shifting issue and traction control light a new thing?
|
How about the old plugs?

You mean the two solenoids, grey one is intake , black one is exhaust

I have replaced those actuators several times over the years and finally got tired of it.
What I have noticed is mine does well until about 50% oil life or so then I get the light and the hard shifting. What I've done for the last couple years is pull the actuators and submerge the entire screen area in seafoam while I change my oil and it seems to do good for awhile... I was told at one point that dirty oil causes the actuators to throw the code. My oil does seem to get very dark very quick so I have pulled the actuators out in between oil changes and clean them but it doesn't seem to last as long as when I do it during the oil change. I have a blue smoke after idling issue and a bit of blow back through the occasional (or lack of) tube off the intake. That may be part of why my oil gets dirty so fast. I'm not sure I'm still working on that. |

A 2006 2LT would have the 2.4, the 2.2 that year did not have VVT.
That blue smoke is most likely the intake valve guide seals are worn out or the piston rings . |

Maybe find a donor HHR and and take the head off that one and put it on your car.
I really do appreciate all your help Oldblue:) You've been a great help |
Thanks, you’re welcome!
