Dear folks,
I'm new to the forum.
Thank you for approving my application to this forum.

Hope to seek advise on 997 C2S (PDK 2009 year)Oxygen Sensors.
Can anyone advise me, if they are narrowband (1 volt) or wideband (more than 1 volt)?

Thank you again guys.

 

The 997.1 is wideband (1.5V), can't imagine the 997.2 being different.

Hi Ynot,
Agreed & thanks for your info shared.

I checked the website you shared & the Part Number is very close to mine.

From website (Sensor #1 & 2. Before Cat.): 9A1-606-168-02-M14
From website (Sensor #3 & 4. After Cat.): 9A1-606-177-01-M114

On my car (Sensor #1 & 2. Before Cat.): 9A1-606-168-02 (blue)
On my car (Sensor #1 & 2. After Cat.): 9A1-606-177-01 (black)

Really appreciate it!

 

Yep, it's the same, on my 997.1 blue is before cats and black is after cats.

 

Thanks again Ynot.
I did a ON search & found that it is indeed Wideband.
Just sharing the findings.
