BMW E46 330i ZHP O2 Oxygen Sensors

[anandoc]

Folks, I am relatively to the ZHP mafia forums - I am more active on the E46F forums. I do not have a ZHP but I have a 2004 330i with about 142,000 KMs now. Bought it at 128,000 KMs. I joined this forum because everybody is so helpful and the level of discussions is so mature, without any flaming.

I have been getting the P2240 code randomly since I bought my car in April this year.



The code usually pops-up when I am cruising along on the highway and I need to accelerate around the 120 km/h range. I believe there is some slight hesitation when I step on the gas and after a few seconds, the MIL comes on. The code disappears after a few days.

When I plug in my PA soft scanner, I get:

2974/A4 - O2-sensor before KAT Bank 2: lines
2973/84 - O2-sensor before KAT Bank 1: lines

I have done a bunch of PM stuff on my car over the summers (with help from orange260z):

- Spark plugs
- Fuel filter
- Full cooling system overhaul
- Fuel pump
- Auto GM transmission fluid+filter change
- Differential fluid change
- Cold weather CCV and hoses
- New OEM DISA valve
- VCG and OFHG replacement
- Upper and lower intake boots
- Brake fluid bleed

Question: Is it worth it to get the O2 sensors posted on this thread and replace them? Or has this something to do with the software version on the DME?

Danewilson, I believe you were getting the same codes on your car, what did you do to fix it?

Oh, and a few pictures of my car from 2 weekends ago:

Sorry, can't help you with the codes but someone will. Welcome BTW. You can also introduce yourself in our New Members section.

Yes. I still have the code after changing out pre and post cat O2 sensors. I think I have a bad cat.

Thanks. Could you describe the symptoms (if any) when you get the codes? How often do you get the codes? I just want to see if there are any similarities between your and my issue. Thanks again.

Hi folks,

I just happened to snag 2x pre-cat O2 sensors (they only had 2 in stock) at an awesome price of CAD $90.23 + taxes each.

Question: Just wanted to confirm that I would be ok with two 17216 sensors (as compared to buying 1x 17215 and 1x 17216)? Thanks!

Yes you will be fine

Yes you will be fine

Thank you!

Yep. They are the same except the wire color and price as far as I can tell.

And I put two of the same in mine (from Amazon).

Thanks Shawn! I could not help but get them at such a low price. I hope this would take take of the CEL I keep getting intermittently.
