Engine Code P0030

[K0PIR]

I've been getting P0030 for some time along with P0135 and P0128. It started out with just P0128 and I could clear it and it wouldn't come back for a month then the other two started showing up this summer.

I replaced the thermostat today and refilled the antifreeze, but I am still getting P0030. According to one website it should be a faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit. Does anyone know where this one is located and a part number in case I need to replace it?



TIA,
Rich

Assuming you have an I5, you have two O2 sensors. #1 would be the first one that the exhaust gasses hit, #2 is the second one. #1 is 12592592, #2 is #12604575

Thanks! Yeah, sorry it's a 2006 H3. I see where the one is on the passengers side right in the heat shield. I guess the other one is downstream of it.

Thanks for the part numbers!

Ya that should be the first O2 sensor located on the manifold above the built-in precat. Easy enough fix. I do believe most after market O2 sensors I found had to be spliced back in if you are replacing. If you can find one with the full length wire and connector you are done in less than 30 mins easily. If not they sell high heat rated quick connect splicers so you might be looking at 40 mins for that one
