Problems/Service/RepairsIf you have a problem with your HHR, want a tip on repairing or performing a particular service to you HHR here is the place to post!
I’ve had rear LCA bushings only last 9 months, depending on the manufacturer. I press out the old bushing and press in a Moog K201285 problem solver bushing. The ones in my 2011 2LT are 4 years old and approximately 85,000 miles.
UPDATESo I picked up and installed new LCAs and aa pair of hubs. That seems to have fixed it. Unfortunately I can't say for sure which one did the fixing but I'm gonna say that both were necessary. When it comes to the front end issues, it's best to be safe then sorry. I was already thinking it was one or the other, and coming here confirmed out could have been either so I just changed them both.
That’s standard practice for these trucklets, I’ve installed one part at a time and didn’t hear silence until after the last part. Still it’s not pulling anymore and you can rest assured it’s fixed.
That is correct. By chance I had the extra money to put into it so might as well. Now though, wouldn't you know, I got the dreaded engine power reduced DIC. It will get up to speed, but it seems to maybe shift kind of hard.. I didn't mess with anything transmission wise. One thing I've noticed about these "trucklets" (I like that term) is that just because you put new wiper fluid in, your radio is going to kapoot! (Not really but the hardcore HHR owners know what I mean. )
Hopefully I will figure this engine power problem, I've seen a few threads on here about it so I think I can!
Engine power reduced is the cause of the harsh shifts. It’s the car’s computers way of getting the driver’s attention to have it looked at.
My guess would be something with the hubs you changed. Get the codes pulled. I’ll bet you got some hub or ABS codes.
So I finally got the codes read, and I have a fault code of P0223 (TPPS circuit voltage too high) and a pending code of P0010 (intake camshaft position sensor). Now, for the P0010 I want to say I read somewhere that could be a bad VVT solenoid also.
To be honest, I'm winging it here, I just happen to know how to use tools and follow instructions. So honestly, whatever help I can get here from all you way smarter HHR owners or by pointing me in the right direction, I'll take it. .
After realizing that most vehicle repairs aren't too incredibly difficult to perform, I can't bring myself to send it to the mechanic. Not unless it's a tranny or engine interior issue, I don't own an engine lift.
The VVT valves are easy; remove the air cleaner then disconnect the wires on the valves remove the bolt remove the valve; reverse to install. I would replace both of them, to save time.
The P0223 probably means replacing the throttle body; That is 4 bolts and 1 electrical connector. Could be some wires frayed and touching ground; look at the wire bundle that goes near the EVAP purge valve bracket.
P0010 almost always indicate a bad VVT solenoid. Not the sensor as a lot of code readers seem to indicate.
I had the P0010 before. Replaced the solenoids(my opinion is replace both of them). My problem was fixed.
Best if you read the How To thread on this forum. Lots of info. Especially the part about the wire plug ins. They can be a little tricky if you’ve never done those before.
P0223 is “Throttle Position (TP) Sensor 2 Circuit High Voltage,” but IDK if that’s the one at the pedal or at the throttle.
Your description, with “TPPS” I think is shorthand for Throttle/Pedal Position Sensor, which to me, says the one under your foot. Coincidently, another member just took one of those apart and fixed it. Don’t think his problem was high voltage tho. He said it was dirty and cleaned it up with good results. Conductive dirt could cause a high voltage condition, I suppose.
