2002 Isuzu 3.2V-6 P0154 and P0155 codes Sign In

I am getting 2 oxygen sensor codes on my 2002 Isuzu Rodeo and need some help. I am getting 0155 and 0154 for bank 2 sensor 1. I replaced the O2 sensor and still get the codes. Cleared the PCM, swapped bank sensors and still get code so I am guessing this is wiring.
What I need is a wiring diagram for the 4 heated O2 sensors so I can trace the wiring back. Also, if these are all looped relative to wiring, why is it only affecting 1 sensor?

Which sensor did you replace?

I replaced the passenger side sensor before the cat and then tried swapping the same sensor from the driver side and the code stayed the same

No, you're looking for the upstream on the driver's side. Make sure you have the right one. You're going to have to test the wiring if you've eliminated the sensor.

That was the problem, swapped sensors and code has not returned.
The really annoys me that the $28 manual tells me the wrong side!

Yep, those manuals are junk. For about the same money you could have gotten a year of AlldataDIY which is the same service we use.
