Hello all, first post.
I'm looking for a correct part number for a 2006 HHR LT 2.2L 02 sensor. During a search, I'm coming up with a whole bunch of different part numbers. Also, what would be the top 2 or 3 brands to go with and their respective part numbers?
The error code I'm getting is PO135 02 sensor heater circuit bank 1 sensor 1
Thanks in advance,
Bob-K

Hello and welcome to the site, first off, there is a possibility of wiring problems with the O2 sensor

Secondly, as you can see here in the RockAuto listing there are economy sensors and daily driver,

I personally use the GM or Delphi parts , a little more money , but it’s the right art , correct electrical connector and the last, evidently 16 years in your case.

RockAuto also offers our members a discount code, here’s how to apply it to your order

Not Bosch, they often cause problems.

NGK/NTK is the maker of the OEM parts. Don't go cheap on this part.

Not sure you can use my case as longevity. The car may be 16 years old, but it only has 23K miles on it. Bought from a friends mother who was 81 and hardly driving it.
Thanks for the advice and I will look into the suggestions.
