Hi All,
Just wanted to find out if any one has encoutered this with their HHR. Set up is 2.4L engine.

The engine light came on after putting oun about 2000+ miles. The manual stated that this could be caused because of either the fuel cap not placed correctly or the the fuel emissions level needed to adjust. It would take a couple of fuel changes for the computer to stabilize itself again.

I had taken a road trip and while driving around the octane in the fuel varied. I started with 87 in California, 87 in Arizona, 88 in New Mexico then back to 87 in California.

Checked the gas cap everything OK. Light Still On
Changed fuel to 91 to improve emissions (per manual), after driving a couple of days it turned Off.
Still using 91 and engine light came on again yesterday. Turned off again today after another trip. Will wait to see if it happens this weekend and will take to dealer for inspection.

If any one has experienced this please let me know might be a bug in the computer or just operator error for varying with fuel octane.

Thanks,
Mtbiker-s

Hi MTB, if the fuel cap is loose, a message wil display on the DIC saying "Fuel Cap Loose." I'm thinking your problem might be somewhere else.

Many users have experienced similar problems due to loose fuses. The design of the fuse box cover, if not placed neatly and squarely on, has a tendency to dislodge several of the fuses - this is a change Chevrolet should make in future production runs. Read more about it here (I hope this solves your prob):

Thanks for the tip Mike,
Will check it out when I get home, I hope this it! I love this forum, there are always cool people willing to pass down their knowledge. :beer:

I hope so too! Post back your results.

What bike are you riding? (brand/model)

Let us know, also, yeah, what type of bicycles and how is the hitch and rack system. I am a racing cyclist, here in Atlanta. I have Specialized Epic Pro and a Merckx Road bike!! I will soon be ordering a hitch to run a rear rack.

I know earlier you posted, that you went with the rec hitch. My HHR has the roof rails, and I know Thule makes adaptors, but my wife is real addimit on not going with the roof rack. Plus it would affect mileage, and a good roof system is quite a bit more investment. Plan is to order the rec, and install with the help of my mechanic friends.

Later,
Mark

I had that happen to me with another car and I did everything to book said and it turned out to be one of the Electrical sensors. So far 3180 miles and smooth rideing.

Well folks I checked the fuses that night. They where loose but nothing happened. The engine light still on over the weekend. Just got back from dropping the car @ the dealer and I'll post back the results later this evening. I'm hoping it's just some sensor bug.

Hey Mark,
Still waiting on a hitch hopefully Hidden Hitch will come up with something less visible. I too was thinking roof, but roof racks tend to get kind of pricey. The Curt Hitches need you to cut something out from the tire base and I'm not to comfortable with the slicing and dicing of my car yet.

The rigs I drag along with me are a Cove G-SpotFR (http://www.covebike.com/gspot.html) 15.5" frame and a GT 1.0 16" frame. I don't mind putting them in the car but I tend to bring back alot of dirt with me. Plus it would just be simpler to place them on a hitch rack. :beer:

It Sounds to me its a bad sensor. Did the car drive like it was losing power?

Hey Mtbiker-s,

What I have read on the recivier hitches, you have to cut some insulation, does not sound like a big deal. I fit my bike inside, not standing though. I have taller bikes, and many times have my wife who rides also. Plus my HHR is the cashmere interior, and would not take much mud, dirt too destroy inside. I will probaly be trying the current Rec Hitches available soon. I will let you know and keep me posted on your setup, also the outcome of the engine light.

Thanks!!

No I did not notice loss of power SIHHR. Everything seemed to be running fine. Just that dammned engine light kept turning on and off.

Hey MarkieMark,
I came across this, Hidden Hitch & DrawTite will have their hitches out by the middle of this month. Plus their hitches say nothing about the insullation being tampered with and use pre existing holes with only hole needing drill enlargement. Plus their cheaper between $111 - $129. Hell I think I will wait for the hidden hitch. Here is the link. http://www.etrailer.com/products.asp?model=HHR&category=hitch&year=2006&make=Chevrolet&t1=&h=e

Hi All,
Just reporting on whats happening with the engine light coming on. The dealer called me up and their kepping the car for a couple of days. It seems like it's the controler module. What is that? I don't know. A controller module I take it :D

They had to place an order for one. The parts guy was cool about the whole thing he said it was nothing major, but hey I guess thats what they always say. He did say they took the car apart. Lets hope that will be the first and last.

I'll keep on posting the drama as I get details.

Isn't the car driveable cant they give it to you back after putting back the parts to drive untill they got the new module.

I guess it's not driveable cause they offered me a rental. I can't wait till I get my little HHR back, they said probably tomorrow, but i'll get more detail on the problem. If you have any questions youd liked me to ask them just post them and I'll get answers for them.

Hi All,
Got the car back on Tuesday, I haven't posted cause I've been kind of busy with work and all. But it turns out that the bad control module was the module that does crank/cam timing. Like SIHHR said it could have been driveable but it would not be recommended. The dealer said the module was defective, that's why it was intermitent. They also said that the wiring on the module was torn like if a rat had been muching on it. But they said that it could be just a defective one. They had not seen any other cars with that problem come by.

I also got a call from Chevy Customer Service to get feedback on my experience of the car. I told them about the incident but of course the person on the phone just wanted to hear good things. Bad time to call. I did suggest more Hp at least 200Hp for future models to compete with the import market 4 cyls. Did brag about how many compliments I get thoug. I'ts a good looking car.

Well enough ramblin.
Take care all
Mtbiker-S

Glad you got your module warranteed MTB.
