Is it possible that I installed it wrong or something? I only get the code sometimes, like 1 out of 3 times starting the car. any ideas are welcomed, thank you.

 

What code is ti your getting ?

 

ur supposed to get code 1 or 2 for 02 sensor..bank 1 or 2....i just replaced my 2nd o2 sensor..the one behind the cat....it's all working fine...got the sensor from the dealer...whopping 150 bucks...rip OFF

 

Yes there are 2 front 02 sensors and 1 rear o2 sensors on the a32 max.
The front one by the radiator is HO2 S1 B2 , Heated,Oxygen,Sensor,First Sensor, Bank Two
The other front by the firewall is HO2 S1 B1 Heated,Oxygen,Sensor,First Sensor Bank One
The most rear by in the Cat is HO2 S2** Heated,Oxygen,Sensor,Second Sensor
On the newer models with 4 o2 sensor they will be
HO2 S1 B2
HO2 S1 B1
HO2 S2 B2
HO2 S2 B1

 

i'm getting 10 01 which means Front Left Htd 02 sensor heater.

 

Ok . put a volt meter on the 2 outside wires of the o2 sensor plug leave it plugged in thou . Start the car and you should see 12+ volts on the meter . If you dont you may not be getting voltage to the heater which would require more diagnosis . If you do 12+ volts you may have another bad sensor .

 

i got the O2 sensor from cheapo2sensors.com (or something like that). if it is a bad one, anyone know if i can exchange it for another one?
