Ok guys.... My check engine light finally came on and it's the O2 sensors. I haven't changed these yet. I have over 155,000 miles on the originals! I was wondering.... with all the knowledge and information that we swap back and forth between users... are there any tips or tricks to changing out the sensors? It's a 97 4x4 EB 5.4. TIA!

 

Take it to Matt. He must repent for his past sins.

Sorry, I couldn't resist.

 

matt will tell you to hire it out, spend the money.

 

WOW! Matt, you just can't get a break! Well maybe you could buy one next time you hire out a job on your ride!

 

lube them up those things can be hard to get out. you might want to get an O2 sensor socket. i usually just use a 7/8" wrench. put antisieze on the threads of the new sensors you'll know why when you try to get the old ones out.

 

Wow. These jokes just get funnier and funnier.

Well, if you hadn't sinned against your fellow xpy owners.............

JK man, I know how much it sucks to work in the cold.

 

Hey I was looking into doing the 02 sensor swap also. Is there (2) or (4) sensors?
Should I purchase them at the dealer? If not then where should I go? Since it is a emissions control part I think that we should take extra caution to be sure we get the correct part. I am going to look in the service manual to see if they show (2) or (4) sensors.
Keep me informed of what you find out and what you do.

 

There are 4 total....2 upstream and 2 downstream. I think they are all (or at least most) made by Bosch so it shouldn't matter where you get them.

 

Yep, what buzzard said!
I looked on my tech manual and it said 2 upstream & 2 downstream.
Bosch is available through any parts store.
Now the next question is if the local parts counter guy needs just my V.I.N. or does he need the calibration code off the door? I am going to start at the dealer and check a price for them. I will post my results.
Thanks Buzzard, as usual you are always helpful.

 

if you can wait try discountautoparts.com I have had good prices and service from them so far

 

Just go to your local parts store, and pick up four of them. I was able to buy some for 50 bucks after tax. They won't need a vin or anything.

 

Here's some info for O2 sensors for my '00 at O'Reilly Auto.

BOSCH Oxygen Sensor
2 per car. Part #15716 Each $49.99
O.E. DESIGN BEFORE CATALYST CAN USE SENSOR WITH LONGER WIRE HARNESS

BOSCH Oxygen Sensor
2 per car. Part #15717 Each $49.99
O.E. DESIGN AFTER CATALYST CAN USE SENSOR WITH LONGER WIRE HARNESS

 

I would have the code read and see which one/s are bad then buy only waht you need.

 

OK.... here's the deal. I purchased my O2 sensors from Advance auto. They were 42.50 each. THe ones that will trip the code are almost always the ones upstream. I believe the code is P1022. Thats the code I think I had on mine. It was O2 sensor upstream on bank 2. I just replaced both of them because I figured if one is bad, the second one can't be far behind. If you haven't done this before then all I can say is..... "HAVE FUN!" The drivers side is easy! The passenger side is a different story! The plug is clipped to the rear of the head. You can't reach it from any where! The sensor is almost impossible to get a wrench on! There is no way that you're gonna get a socket on it! Ford needs to have one of their engineers try to change some of these replaceable parts with the motor in the vehicle! All in all it took me almost 3 hrs to change both. Breakdown as follows:


Drivers side.... 15 min
Passenger side 2 hrs and 45 min, most of this time is trying to unplug the stupid connector!

As far as anti seize.... the new sensors come with anti seize already on them. My old sensors came right out! I also live in the south with very little salt on the roads in the winter. As far as changing them in the cold...... I wouldn't change anything in the cold or on the ground in the winter unless it was absolutely necessary! I also don't have this problem because I have a heated garage! My suggestion for anyone going to do this.... Have plenty of patience.... I would rather change the spark plugs than have to do the passenger side O2 sensor again! Good luck for anyone wanting to try this!
