Where is the second 02 sensor
Forgive me, but I normally work on TDI's. So my question may seem stupid. I am trying to help with a 2.0 liter AVH in a 2001 New Beetle. Originally, the car had a bad cat cel and a fuel trim cel. I replaced the cat and the o2 sensor at the rear of the cat. The original cat only had 1 o2 sensor hole, so I installed the same type cat and put in a new o2 sensor. Good news, no more cat cels. bad news is that I'm still getting a fuel trim cel. When I use the Vag-Com is shows a pre cat o2 sensor reading and the voltage is 1.5V and it is supposed to be no more than 1.0V. So, long story short, I assume I have a second o2 sensor to change but can't find it. It's not on the cat. any one got a picture. I've searched the forums and some say New Beetles only have 1 others say there's 1 on the exhaust manifold. the Vag clearly shows two o2 sensor readings. Any help greatly appreciated.
