2002 Explorer EB 4.6 V8 Codes
The dreaded "service engine soon" light came on in my explorer yesterday and I had the codes read. It looks like it's an O2 sensor. The codes were -
P0132
P1132
How do I know which O2 sensor it is?
Thanks in advance!

Bank 1 is on the passanger side, sensor 1 is on the engine side of the 1st cat. This is worth replacing, in that the upper ox sensors help control mixture. I have verfied the failure before by switching the sensors (bank 1 to 2, 2 to 1) clearing the code, and seeing if the code switches banks. It pretty much allways does, so I end up buying a new sensor

It is recommended to change O2 sensors every 70k miles. My sisters explorer has almost 170k on it with the orig o2s though.

WOW!! 70,000 miles that seem's premature vs and other vehicle I've ever owned. I may do it though just to eliminate any problems down the road. Is this a difficult job and what is the cost?

This is from one website concerning O2 sensor replacement:
Bosch recommends replacing unheated one- or two-wire O2 sensors on 1976 through early 1990s applications every 30,000 to 50,000 miles. Heated three and four-wire O2 sensors on mid-1980s through mid-1990s applications should be changed every 60,000 miles. And on 1996 and newer OBD II-equipped vehicles, the recommended replacement interval is 100,000 miles.
