I had my PCM scanned today and it has this code PO153.
I looked it up on shoebox's web page.
Heated Oxygen Sensor (HO2S) slow response Bank 2 Sensor 1
What I need to know is which 02 sensor is it?
From what I understand Sensor 1 means it is one of the front ones before the Cat.
And sensor 2 would be after the cat right?
If I have this all right the all I need to know is which is (bank 1) & (bank 2).
BTW this means I need to change the sensor right?


Thanks,
Chris G.

 

Bank 1 = LH or driver's side
Bank 2 = RH or passenger's side
Sensor 1 = before cat
Sensor 2 = after cat

Very well could be a bad sensor.

 

Thanks as always Rob.
