O2 Sensor Identification

[mtmscs4]

Need some help... Pulled code P0134 which states "02 circuit no activity detected, Bank 1, Sensor 1"

Unable to determine if this is the driver or passenger's side pre or post cat sensor. Bentley guide makes a great desk weight but isn't super helpful.

Thanks. Always great support from this forum.

Drivers side front Sensor. Sounds like it died abruptly (extremely rare) or a connection issue. The O2 plugs are on the firewall, passenger side. The front sensors are the same, Black plugs. The rear are the Green and Brown plugs.

Drivers side if you have a RHD RS6? All the pdfs i have on my phone for the beast say that bank one is on the right side....

Passenger side if you have a car in the US. Right Bank. Pre Cat.
