CEL 0413 - O2 Sensor (left bank)

Got a 0413 code on my '99 GLE that is about to hit 100k in about 50 miles. I know it is the O2 sensor but I'm not sure which one. I know the 95s and up have 2 sensors upstream (one per cylinder bank) and 1 down.

There is one right below the oil dipstick and another I can't see, so I'm wondering which I'm dealing with here.

I've looked here http://www.courtesyparts.com/A32_O2-sensors.html but this only goes up to '98. I'm assuming though that from this diagram that the "front" is also referred to as the "left" so the location on this diagram would hold true for my '99 as well, meaning the one under the oil dipstick is the one I'm after.

Your thoughts and thanks.

Yes. The left bank is the bank of cylinders closest to the radiator. The o2 sensor you need to replace is the one in the y-pipe closest to the radiator.

ECU code 0503 - front R 02 sensor

I had this code 3 weeks ago, telling me to replace the Front Right 02 sensor, but now the CEL has disappeared & there is only a "ghost" Knock Sensor code.

Should i still have my 02 sensor replaced???

THanks for any help!

Here is a hint - go to the Member's ride forum and go dicuss some wheels or tires... don't tell anyone I told you to do that.

When you have made 15 USEFUL posts, then come back and post your question. I know your intentions are good (unlike other newbies) - but its the other newbies that have forced the implemention of this 15-post rule.

I recently had the code 0413 too. I did also look up which o2 sensor but I am confused of which o2 sensor to replace. I have a 99 SE-L and I am wondering which color wire o2 sensor I am suppose to change or easier which one by this diagram. Thanks!
