Thanks FAR888, it appears to be item#6.I cannot be certain, especially since you called the parts you need 'clips', but could it be that you need one of the brackets labelled 5 and 6 in the parts diagram at the link below?:
2000 MERCEDES-BENZ ML320 Parts - Mercedes Benz of Fort Lauderdale
The Denso part # is correct for your vehicle, but a search with Autohauz reveals that they only sell Bosch sensors.Guys,
Thanks for the input. I just read it again and so far, no codes. I will keep a closer look and see if it pops up again. I'm hoping to get it smog checked tomorrow.
Response to some of the questions. It is a Denso Part#234-4174 (both sides) purchased online from autohausaz.com
My OBDii scanner is an Actron CP9135. Its several years old, maybe its time for a firmware update or something..
I forgot to mention, in the process of replacing the sensors, the clip holders were brittle and it broke. I managed to zip-tie them temporarily. Do you guys happen to know the part# for those clips?
Sorry 43sqd...I must got this one from 234-4172 - Auto Parts Warehouse
