E46 DIY #1 Changing Pre-Cat Oxygen Sensor & P1189/P1188 Fault Code Repair Attempt #1

[vijaych1209]

Hi I am planning to replace my 323ci bank 2 sensor 1 and the question i have is if the sensor is any different than bank 1 sensor 1 which i replaced few weeks ago.

I used this - Bosch 13477 for bank 1 sensor 1 and i am told i use Bosch Part No. 15109 for bank 2 sensor 1 which has a longer wire to it.

[lightdark101]

@vijaych1209 Bosch part No. 15109 is for a Post-Cat Oxygen Sensor (Bank 1 or 2 Sensor 2) and reason why the wire is longer because the wire goes from the bottom of the car to the top of the engine by the fuel rail...

And most of all its the wrong sensor for this job...

And the sensor for Bank 1 sensor 1 is identical and the same to Bank 2 sensor 1 (No. 19477)

Sorry for jumping around, hope i answered everything and cleared out any confusion

Remove the engine cover and it is way easier to get to the back sensor.

My car had recently been experiencing some difficulty when accelerating from a complete stop. This morning I turn my car on i get a check engine light and I was getting quite a bit of vibration in the cab. So I drove to school and my car seemed to be running about half of its usual power. Well after I went to class etc.. I drove my car home and it seemed fine but the check engine light was still on. Do you have any guess to what the problem could be I have a 99 323i and obviously its anE46.Help

[cthulhuXD]

my E46 has 0174 system too lean (bank 2)...is this the o2 sensor?

i going to change the o2 sensor.. but im not sure cause my car has two O2 Sensors..

can you help me please..!!

[lightdark101]

@cthulhuXD try cleaning your MAF and use seafoam in your gas tank to clean your injectors... check for cracks and leaks in your intake system...see if that works... if it still shows up replace the O2 and if it still does... do a test swap or replace your MAF

[askfskpsk]

[alexlex85]

can you tell me if the lambda sensors are all the same part number?

are they all the same or slightly different?

many thanks

[lightdark101]

@alexlex85 Lambda aka O2 sensors for the 323i or Ci are the same since we have the same engine and this is the same Bosch Oxygen Sensor #13477.

BUT... Thats at autozone; i'm not sure if thats the same part number as other places. So depending on where you shop just make sure if its upstream (Pre-cat) or downstream (post-cat). Hope that answers everything

Thanks for taking the time to make this video! I'll be changing mine this weekend, so it was good to watch this as a visual demonstration of what to do.

[martinBmw940]

whats the torque u need to do on the oxygen sensor???

[lightdark101]

@martinBmw940 it says at 12:16

50nm or 37lbs/ft

Got me scared and made me thought that i forgot to edit it in when editing the video

[jmoto99]

god... everything in the engine bat is crammed in there

[IDoNotReply]

Ok, so I'll check for cracks first before replacing sensors. I'm assuming bank 2 and bank 1 are both pre-cat? Aren't there 4 O2 sensors? Where are the other 2?

Thanks for the vid. very helpful.

[lightdark101]

@IDoNotReply the remainder O2 sensors; which are post-cats, are located near the down pipe curve on the bottom of your car. But both of them are kind of difficult to get since its small place and their connectors are located where your fuel rails are located (under the plastic engine cover held by 2 10mm bolts) I was eventually going to do a video on post cat sensors but kind of short on money.

Bank 2 sensor 1 is the o2 sensor closes to the fire wall and bank 1 sensor 1 is the one next to it.
