New to Board - O2 Sensor Problem
Hello, I'm new to this board (first post). I've got a '98 Explorer Sport 4x4 w/ a 4L V6. I have an upstream O2 sensor slow response (code P 0153). My Chilton's says it's the Bank 2 Sensor 1 Unit. Can someone please tell me which O2 sensor this is (driver or passenger side exhaust pipe?). Also, is there some tip on how to reach the electrical connectors for the sensors? They are almost unreachable. I tried for about an hour to disconnect the connector on the passenger side O2 sensor with no luck. Is there a special tool that's needed?
I've changed O2 sensors on other vehicles before, but I've never ran up against any like these. Help would be appreciated.
Thanks,
kiteman

same code and I can't remember which side it was. Its 4am and I'm a little dazed and no manual. I believe Bank 1 is the same side as spark plug #1 so Bank 2 is the drivers side. I remember having to pull the wire retainer out of where it hooked to the transmission so it would drop down enough to get at the connector locking tab. If you cut the locking tab off the old connector, a box wrench will slip over the wire down to the sensor.

Thanks! Makes sense for the banks to correspond to the plug numbers. I'll try to pry the connector retainer out of where it's hooked to the car. Doesn't seem to be very much slack in the wires, but there's probably just enough to get at the connector.
Really appreciate the help.

I have a 97 mountaineer 5.0- it may be the same sensor. I had the same code, and replaced the sensor on the driver side, right by the tranny bell housing, connector was easy to get to. and it fixed the problem. Spendy sensor though. About $80.

The connector is on a retainer clip attached to the rear of the engine block. It's sandwiched between the block and the firewall. Can't reach it from the top, and there's barely enough room to get one hand in the space from the bottom. I don't know why they put it there, except to make it really hard to work on.
I tried to pry it out of the retainer clip without much success yet. Don't want to put too much force on it and break the plastic. Will keep working on it. If someone has a tip on how to get it disconnected, I'd welcome it.
With O2 sensors usually the hard part is getting them loose. Never figured disconnecting the wires would be so much work.
I agree it's pricey, but it sure beats having the shop do it. $$$$$$.
