P0133 O2 sensor...Bank1 Sensor1???
Hi, my 97 Expedition (4x4 5.4L) 's check engine light is on.
Code reader shows p0133 which means O2 sensor Circuit Slow Response Bank 1 Sensor 1.
Is this means I need to replace the O2 sensor?
Is Bank 1 the driver side or persenger side?
Is Sensor 1 before or after the cat?
Thanks in advance for you help

Have you found out where the location of the oxygen sensor is when the ODBII tester referes to Bank 1 Sensor 1. My truck has the same issue.
I also have 1 and 2 misfiring along with other things. So I guess I could cross reference which side cylinder 1 and 2 is on, but thought I would ask you to see?

Bank One is a multinational bank holding company in the process of merging with JP Morgan Chase......
Bank 1 is the driver side #1 is upstream. IF one has failed, you might as well replace the pair of upstream units at the same time. They are normally good for 80K to 100K miles.

Just wondering if it's a PITA to change the sensors? and if not, any special tools required? I'm around 112k and I don't think any have been changed since the truck was new (checked all the receipts). I've just changed my plugs this past weekend, and you want to talk about a PITA!
Thanks,
Phil
