I just bought a 2003 H2.

Everything is good and the seller explain to me before I bought it that bank 1 and 2 oxygen sensors need to be repair.

So we took it to a mechanic and the mechanic got the code that bank 1 and bank 2 need to be replaced as the seller stated...

To be honest I have no idea what oxygen sensors I need to buy.

Im not trying to pay dealer prices so I checked on ebay and came up with this:

New AC Delco Oxygen Sensor GM Vehicles Various 213 3867 | eBay

&

New AC Delco Oxygen Sensor GM Vehicles Various 213 1161 | eBay



is that correct? If so which one should I get? and do I need to buy 2 of the same one?

Or can you link me to some that are inexpensive? (preferably on ebay)

I have no idea. There for I am seeking help from you guys who have knowledge in this.


I highly appreciate it. Thank You so much.

 

I would be concerned about buying parts like that from Ebay. There is a huge problem with knock off automotive parts. Even though the ad say AC delco they might be knockoffs.
When you do buy 02 sensors Delphi and Bosch are two high quality brands. Have you checked with your local parts store?

 

Thank you for your reply. I haven't checked yet but I guess I am better off checking my local parts store.

 

I bought on ebay once and the O2 sensor looked good but when I plugged it in the same code came up, someone did a really good job cleaning it.

So you're saying they were used? If so that is just a god damn shame.


I'm just going to buy them in person in a shop.
