haven’t seen one of these but seen a few questions on this. so ill try to explain it this is my 1st DIY thread so bear with me.
they could have make the sensors the same and saved money but they didn’t the only difference is the angle of the plug. and you could swap them is the grooves on the connectors weren’t reversed

TOOLS: 10mm socket, 10mm box end wrench, flat head screw driver.

1. disconnect batt.
2. get to work remove intake and (engine cover 2 bolts and 2 nuts)
3. remove upper plenum
4. remove lower plenum
5. move wire bundle to access bank 1 sensor
6. remove 1 10 mm bolt and pull the sensor out
7. replace with new sensor
8. remove breather hose from valve cover (forgot to circle that one but youll see it. if you dont get some glasses)
9. remove 1 10 mm bolt and pull out bank 2 sensor
10 . replace sentor
11. re-assemly, johnny 5
12. reconnect batt.

PIC 1: Upper plenum (remove bolts(alot), nuts and 3 or 4 hoses,i think there is one one the bottom of the TB, circled)

PIC 2: lower plenum (remove 6 bolts in center, 2 nuts and 1 hose, circled)


PIC 3: sensor positions (left side = passenger)


PIC 4: sensor before removal(1 10mm bolt holds that sucker in and an “O” ring gotta wiggle it to get it out)


PIC 5: sensor after removal

 

Bank 2 is similar except the sensor has an angled connector(and is on the opposite side)

    I replaced sensor one last month then sensor two failed last week. I replaced sensor two and reset the service engine soon light. Now the engine idles at about 1200 to 1400 rpm.
    When I had the trottle body off, I cleaned it out but neither of these things should make the idle stay high.
    Any tips on what to do?
