P0158 O2 Sensor Location

[QBOY]

I have the following DTC codes P0325 Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)P0159 02 Circuit Slow Response (Bank 2 Sensor 2)P0158 02 Circuit High Voltage (Bank 2 Sensor 2)

Now P0158 was the first to come on. I was trying to research it and find out which sensor it was - I think I found out that it was one of the Rear sensors but what side is it - Drivers or Passenger.

Could one of these coded be causing the other or are both the Knock sensor and the O2 sensors bad?

Please - Any information would be greatly appreciated!

You might benefit from replacing all of the O2 sensors with 103K miles on the car. Similarly, replace both knock sensors with a new harness. sparkplugs.com has the O2 sensors.

Good luck!
