I have a 2006 HHR w/2.4 engine. I'm getting check engine light w/codes p0030, p0033, and p0135. Disconnected battery but codes came back. I checked the fuses, can't find blown fuse. The problem seems to have no effect on performance. Any sujections will be greatly appreciated.

P0033? Not likely with the 2.4, as the p0033 refers to the turbo boost.

P0030 HO2S Heater Control Circuit Sensor 1
P0033 Turbocharger Bypass Valve Solenoid Control Circuit
P0135 HO2S Heater Performance Sensor 1
Ok now I'm confused, did the 2.4 have a turbo in 2006? heater control and performance sensors?
the O2 sensors are heated and they could trip the code s P0030 and P0135.
I'm sure one of us will have some answers. meanwhile check for loose wires and fuse box under the hood

I Googled "P0135" and got:

And P0030:

And 9 threads on the first page using the SEARCH box. "p0135" Cut n' paste it.

Since everyone wants me to do the Googling. That's $1,530 please.

Check the wiring to the 02 sensor if all ok and fuses are good then replace the 02 sensor. Sensor number one is the one before the cat. Convertor. I don't no about the turbo code it may just be a glitch it the code reader.

I think fingers were aimed at the 2 for a P0032, also a #1 HO2 sensor code.
