Just bought Actron OBDII Code scanner. It works great, but
I got P0152 Oxygen sensor Circuit High Voltage Bank 2 Sensor 1
I know its the upstream sensor, but I dont know which of the two is sensor
1. Anyone pull this code before or replace their O2 sensor?

 

Bank 1 applies to driver side.
Bank 2 applies to passenger side.
Sensor 1 is upstream, sensor 2 is downstream.

 

Actually, bank 2 is toward the front of the car, bank 1 is toward the rear.

 

how much for the OBDII Code scanner?

 

I paid 150.00, it has the ability to read codes that have not made the light go off yet also, it can turn off the light(erase stored codes) also does emissions testing. Really
nice tool for 95 and newer vehicles. This one reads what the code is in a scrolling text
The reason I bought it is to avoid dealer charges and bs. Actually the dealer has been
good to me on my only visit thus far they replaced my tranny at 58,500 two weeks ago
only a week after I got my 00 GLE good thing I read about tranny probs on the forum
