How to Test and Replace Rear ABS Speed Sensor 1998 Dodge Ram 1500 Code PO720 P0720 

Thank you! Thank you! Thank you! I'm more of a parts changer than a mechanic. While trying to wrangle the connectors apart 6 inches away the wires conduit about came apart. Upon inspection saw a broke wire. Checked the sensor like you did with an ohm meter without having to remove sensor. Showed resistance. Repaired wires. Disconnected and reconnected battery. Test drove. Eureka! Speedometer works, no check engine, or parking brake light. Thanks again Jay Gould. You are an outstanding intructor by the way.

This is one of the best do it yourself video I’ve ever seen. Very detail and straight to the point. Not a lot of long drawn out introduction but straight to the point.

Thank you for talking about how to remove the different clips and such. Many other people completely skip that part

Your camera work is some of the best I’ve seen on RU-vid and helping out like installing and uninstalling something. Thank you.

I agree with everyone else--this was a GREAT video. If I had a dollar for every time I watched a video trying to learn how to do something, and heard "next, unplug the sensor. Then, go ahead and___..." meanwhile I end up spending 20 minutes reaching through a tight space, fighting with the damn sensor because I am not clear on how the clip operates and I am trying not to break anything. And inevitably I will end up injuring myself or breaking the clip, and then I might have to spend a bunch more time find a replacement harness or whatever and wait for it to arrive.

Now that's how you make a good, helpful video

Thanks Jay! I just picked up a pristine '99 2500 Cummins shortbed quad cab and the ABS/Brake light were on- Went to auto parts store, picked up the sensor, removed the old sensor, popped in the new and WA-LAA ! This is one one of the CLEAREST and well made "how to" videos I've ever watched. Great job and Thanks again!!!

Thanks for posting this video. I fixed my wife’s 1998 Ram SST in less than a half hour. It took longer to get the spare tire in and out than to swap out the sensor!

I've have watches a few different videos on this subject so far and none of them were very helpful. This is BY FAR, the best, most informative video I've seen, and I dont need to watch anymore after this. The other videos showed how to remove the first nut and then the bolt, and that's it... I was more interested in seeing how to remove the old sensor without destroying anything else. This was a perfect video for that. My 06 ram 1500 has been constantly flashing the abs and brake light at me(I'm talking 20 times a minute) and dings everytime. Sometimes the lights will stay on but when that happens, my cruise control no longer works and the same goes for my 4 wheel drive on the fly shifting. New sensor is coming today and I was hoping to go out and get the old sensor off before it gets here. Thank you for not only taking the time to make the video, but to be so thorough too.

Sir, thank you for being straight and to the point! Wonderful video!!!

Like James Baker stated, I too have watched a few different videos on this matter and this one by far the most informative. Thank you so much Jay

Outstanding Video on replacing this sensor! It gave me absolute confidence toward replacing mine on my Dodge 3500 Cummins!!!👍🏿

great vid! perfect lighting and camera angle! thanks for showing socket sizes too

Super appreciate this video, they’ve apparently learned because mine came with a modified guard already on it.

That was the MOST informative and detailed video I believe I have ever watched !

I know this is an old post but great video and it helped me replace my sensor, no lights.

Great informative video that's straight to the point, clearly explained and awesome visibility!

Very clear and to the point. Great help on the rear-end speed amateur sensor

Awesome video thank you just fixed my 98 Dodge Ram 1500.

This is an excellent video! Exactly what I needed to diagnose and repair an issue I have on my identical truck.

Great video! Very detailed and informative. Thank you.

Nice video and it is similar for the 2005 Dodge Durango, mine however did not have cover and only a bolt to secure the sensor and the brake lines. But anyone that has this should follow your lead on this!Thanks!

Thank you for the info. It helped tremendously for me with my 02 quad cab.

great video!! Thank you for being so thorough!

Thank you for the Greatly explained video!

Thanks for the great a info this is helping me with my 04 ran 2500

Thank you. Excellent. Appreciate your helpful video.

Man you really helped me out thank you

THANKS FOR VIDEO .....THIS SAVED ME HUNDREDS OF DOL;AARS FOR ME TO DO IT ...

Very good video

excellent video, including how to test if the sensor is bad 👌 I am going to try this in my Ram Charger 2000, it is the same platform as 1500

Very good video. other videos have to lecture you on all kinds of other stuff , like how this one gets right to it

Top shelf Sir! Thanks

Thanks for you vídeo we help me and my Dodge ram 1500 1998 v8 5.9

Well explained thank you.

Thank you very much for this great video Jay. It has saved me a lot of time and effort and caught a mistake by the parts store when the tried to sell me a sensor without the needed wiring harness. Very much appreciated!

glad i found this this is what mines doing

Fantastic post

Thank you sir!!🤙

I had the same problem with my 1998 Dodge 1500 a few years ago, replaced it with a Dorman part# 970-024

Thanks for sharing

Nice video

thank you

Thank You😁

You should make more 2nd gen dodge videos!

Thanks!

If these wheel speed sensors are bad can it cause transmission shifting issues after replacing the output shaft sensor

Mine was very difficult to get off and on..had to rubber hammer it no joke to go in. It did fix my speedometer bit my brake light and abs are still on. What else could it be? Replace breaks and rotors because I know they are trash too and also brake reservoir empty but when I fill does not fix the brake lights or abs. Help

I have a 99, and I get the same lights, ABD and Brake, but not the Check Engine light. Will this be the same problem still?

Great and detailed video, nice work. I do have a question, I have identical symptom on my 1999 Ram 5.9L Magnum 4x4 but the error code is P0500 Vehicle Speed Sensor. Would you say it’s the same sensor on the rear differential as in your video causing this issue? Thx.

Is there a reason the replacement is backwards and does anyone make them the right way so I dont have to order an extention,thanks for some very informative videos

Para la mamalona!!!

My light is on has been for years. What really concerns me is that there are no error codes!! Wiring appears to be in place. Any thoughts???

So my speedometer isn't going past 10mph but I have no lights what so ever, is it still my sensor or my cluster?😊

I have abs and brake lights also plus my pedal goes to the floor did your pedal go to the floor thank you

If that doesn’t correct issue replace front wheel speed sensors also .

have a 2001 Dakota 4x4 , the door bell starts chiming when I put it in gear and start rolling, when I stop at a stop light it stops. The headlights are also flashing, interior lights and wipers come on intermittently, anyone have any ideas what could be causing this?? Thanks

UGH! I was following along nicely until 3:21, then mine snapped off, clean as a whistle. The only thing remaining (Completely unreachable) in the Sensor hole is the plastic sensor cap. I thought about going in from inside, but the gears would be in the way. So, I will be digging it out from up top tomorrow morning. Not looking forward to this project.

Why did they change the mounting Sensor

Where did you get the part from because the ones I keep getting aren’t fitting

My 02 dodge cargo van has the abs and brake light on all the time(my speedometer works) I get 1.81 resistance on sensor.wiring is good. Fluid is good.Brake pads are new.Brakes fine.Fuses are good.no leaks around calipers. My scanner can't read its abs module. Is there anything else I can test? I'm just out of ideas. Any suggestions anyone?? I'm getting really fustrated with this thing.

Mine does the same thing and also the seat belt light comes on? 😏 I need help

I changed out the sensor and the brake and abs light is still on. What’s next?

I had the same problem in a 2004 ram. Speedo would start at about 20. After replacing the sensor, speedo doesn't come on at all. Any ideas

I did all this and still had the lights any help ????

Where's the speed sensor @ on a 99 Dodge Durango

If that doesn’t correct issue replace front wheel speed sensors also .
