Where is the 2nd oxygen sensor? 1998 5 liter V8

[ThreeFords]

I have a 1998 Explorer AWD with the 5 liter V8. I am consistently getting a Check Engine light because of the oxygen sensor. I have changed the oxygen sensor that is accessible under the car on the exhaust, and that cleared the check engine for a while, but the check engine light is back.

Is there another oxygen sensor in this 5.0 liter V8?

There are four of them. The code will tell you exactly which one it is.

On three of them the connectors are very had to get on, plus one sensor by itself is also hard to get to - on a V8 AWD:

OK, here is the code I'm getting:

P0133
Oxygen Sensor
Circuit Slow
Response Bank 1
Sensor 1

Thank for your help.

P0133 - O2 sensor circuit slow response Bank1 Sensor1 - this is the passenger side front O2 sensor.

The one that I think you changed was the driver side, like in the pic below (P0153 - O2 sensor circuit slow response Bank2 Sensor1- Driver's side front O2 sensor):

Thanks! That diagram and the link to the removal of the center console was exactly what I needed.

Sonic you are correct. Many people get this confused as with a lot of V8 engines including non v8 engines, bank 1 is in fact the drivers side of the vehicle

To where the Ford 5.0 and a ton of their other gas engines are actually opposite where 1-4 is on the passenger side and 5-8 is the drivers side. Versus say my Hemi Jeep is 1/3/5/7 bank 1 drivers side, 2/4/6/8 bank 2 passenger side.

I was confused too, until I had to change my spark plugs

Sonic, where do you find that particular diagram?

I was wondering if you had a part number for the oxygen sensor.
