Ford P0720 Speed Sensor Error Code Repair
HTML-код
- Опубликовано: 17 сен 2024
- OBD2 CAN bus reader scanned P0720 for transmission output shaft speed sensor circuit failure. The check engine light was illuminated, the speedometer was not working and upshifts were slow and sluggish. The green overdrive off light was flashing.The OSS measures driveshaft rotations for spedo and odometer. Shaft RPM also controls shifting. On mine the wiring harness had broken wire. I found a rat's nest under hood and I assume the rat chewed through the cable. It was impossible to get hands up there to repair so transmission had to be lowered to gain access. Once fixed use OBDII code reader to scan bus and clear P720 CEL error. Could also get P0722 or P0731 DTC malfunction trouble readings for Insufficient Input.
Instead of gluing the bolt into the socket, put a small piece of masking tape over the head of the bolt and insert it in the socket. That will hold the bolt in the socket for you while you get it started and no mess to clean of your tools.
Or you can use a piece of a napkin, which is more common than masking tape )
I like to use the heat shrink tubing that has silicone inside when you heat the heat shrink it it activates the silicone and keeps the moisture out 👍
Where do you get thoses
Rat: "Lets sneak up there between the tiny finger space where the output speed sensor wires are and chew on them!" WTF really?
I have had a few other issues with rats chewing through wires as well. I keep a lot of rat poison bait stations all over the property but they still find a way to damage my cars.
Just wondering, did you put Jack stands or at least a steel rim under the car before you climbed under? A Crown Victoria will crush you like a bug!😱
Not to rain on your parade, but if you clear the codes and don't run the car through a drive cycle, you really don't know if it was fixed, because it could come back.
The wiring was clearly burnt, causing the problem.He fixed it :) .Job done.
How long is the drive cycle? I replaced both sensors on my transmission and it comes back if I disconnect the battery. But if I clear the code with my scanner it drives fine but my speedometer still doesn't work. Do I have to complete the drive cycle before my speedometer starts to work again?
Been trying to locate this forever!! Still cannot find it or see one on my 2001 Grand Marquis GS O/D flashing, and check engine light on... already found and replaced other sensor (VSS)
Hey I've replaced my Mazda b 3000 speed sensor on the rear differential pumpkin and installed new vss and the overdrive light blinking on and off after id say of 20 or so miles of driving
Any ideas why
Is there another speed sensor on my truck is only one I see one on the rear differential pumpkin
Mine doesn't engage in forward till i rev it up just threw the same code with flashing od light truck is a 2001 f150 4r70w also the sensor is leaking oil out when I pulled the connector
Same thing with my 2005 f150 did you ever get it fixed?
Same here. Still figuring it out
Same issues. You figure it out?
@@mrN8Vman fixed it with a replacement transmission and now sold em all and went with 7.3s
2007 mercury mountaineer p0720 speed sensor located
I have 08 Ford f150 I bought another transmission but this one only has one speed sensor an my 08 tranny has 2 an outer an an inner is there anyway to bypass it so I can get it to shift in the tranny I bought mounted in there perfect it goes in drive but it just not shifting gears
Thats alot of shrink tubing😂
Better safe. I also wrap a lot of tape. It's a big bulge but who will see.
Where can i buy both sensors?
How about p1502 on a 1998 Lincoln Town Car?
What is a spomner?
Could faulty speed sensor cause p0741
I have a 2007 Ford Focus and I'm having the issue. And I'm not how much of a mechanic where do I find my output on my car? if anyone knows??
If anyone could help I have a 1998 my speedometer does not work I suspect the speed sensor on the transmission but I do not have a check engine light or a code, I sure hope it's not the speedometer
Would is be the same for a 2009? I can't find any thing on that year
Yes it has same transmission. The video shows how to change the speed sensor.
Thank you dude I just wanted to make sure
Just had this code come up for my 2008 Ford Fusion. Had a guy at O'Reilly's tell me that it's the whole transmission that was failing, which freaked me out. Is it possible to just replace the speed sensor, or is it recommended to repair the whole transmission? I know jack about cars.
Just the speed sensor needs replacement. My video show how. The guy at O'Reilly's is working at minimum wage for a reason.
Cant find it on my 09 crown Victoria
How is that car so clean
20 year old California cars all look like new underneath.
Great Educational Video!
Did u pull the whole transmission down to fix the wire
I did have to lower transmission a few inches to get to the wire. Was too tight a space. Can replace speed sensor without lowering.
@@KentDiego you say speed sensor can be replaced without lowering transmission
@@LiilTyweezy yes, just did mine but it didnt fix anything
could a speed sensor cause a p0758 code? mazda 3
