2001 Dodge Dakota - 4.7L Oxygen (O2) Sensor Replacement (Bank 2 Sensor 1)

Replacing the O2 sensor Bank 2 (Passenger Side) Sensor 1 (Before catalytic converter) on the 4.7L Dakota. This is the most difficult of the sensors, as it sits so close to the exhaust manifold, and the wire connection sits on top of the transmission. After disconnecting the wire connection, I hight recommend re-routing the connection to an accessible location! :-)

i had a friend take my truck to the shop for the check engine signal. reading the paperwork from the shop it says "1 DTC right Bank (Upstream) O2 sensor" Which sensor would that be? i would rather save money and just replace one for now rather to guess which one it is. thanks.

@therevelation88 Right bank is the passenger side, upstream is the sensor BEFORE your catalytic converter, closes to the engine/exhaust manifold. You can pick up a Bosch sensor for around $50 bucks and replace it yourself. The 4.7 liters are brutal on the sensors, so it is not uncommon to replace O2 sensors on our trucks. Good luck and let me know how it turns out! By the way, what was the DTC code, was it a P03xx or something?

I also have a dodge dakota, and have the same exact drop light! Thanks for the vid,

@ShitMyCatsOnFire You're very welcome, I am glad the video helped. One thing to keep in mind with those sensors...be patient and you will get them out.

the red tab slides sideways like he does in the video with a screwdriver away from the connector .

then just press in the center in-between the red tab prongs with your 1st finger (this is the actual clip that holds them together thats why they dont come apart after sliding the red tab!) and at the same time pull both connectors apart

@therevelation88 i mean the code was "not" written on the paper

[therevelation88]

@TheTexasCoder unfortunately the code was written on the paperwork my friend brought back from the shop. i just ordered a bosch sensor without any wire splicing or buying a sensor bung for little less then 60. hopefully it will come in during the week so i can install it. i took a look under the truck and found that the driver sensor looks much easier to handle than the passenger side,

@TheTexasCoder Oh, I meant seeing how the connector actually comes off. Like where to stick the flat head. I can hardly see the damn thing.lol I'm trying to get the front passenger side one off so I can extend it for my headers. I messed up and put the rear one in instead of the front one and it fowled out the plugs on that side. I also had to soak the o2 sensor in gas to clean the soot off.

@sixfootface I ended up getting an O2 sensor wrench kit from Harbor Frieght. That ended up being the final tool that knocked the sensor loose. It was a bear, but it finally came out.

@Chesterdacat I'd like to see HOW to take the plug off properly. I've been fighting with it for a while and I don't want to break anything. Great video other than that! Thank you!
