    Have a 1997 Mazda B4000, 4.0l, automatic, 2 wheel drive that is throwing codes P0133 and P0153. Both banks have slow response. When I do a live read of system, all 3 O2 sensors are showing 0.000 after running for 45 minutes and longer. Read somewhere else that it may be caused by some other place. Not sure what else to do or where to start. Any advice or direction?

    Also, the connectors might be dirty, or, disconnected.
    They can be checked with a volt meter too, while the engine is warming up.

    Thanks for your suggestions! Think I am having an issue with my Actron CP9580 not working 100% with my 97 truck. When I go to view data, that is where I see the O2 sensors reading 0.000 but also I have ST FTRM1 & 2, LT FTRM1 & 2 reading -100%. So something is definitely not reading right with my live data. But the codes P0133 and P0153 were both being thrown. Replaced the Bank 1 Sensor 1 and the P0133 cleared. After the P0153 popped up again, I replaced the Bank 2 Sensor 1 O2 sensor. All errors have cleaned and passed emissions test this morning with no check engine light on! No on to other repairs! Thanks again for advice and help!
