    I don't know where u got the info that the code means speed sensor, according to my manual it says the the TCM has requested the MIL be turned on. There seems to be allot of confusion on this code, u need to see the dealer, u may have a slipping transmission.

I have been diving into my factory service manual, and the P0700 should have another trans trouble code stored with it, a "Generic" code reader may not be able to read the other trans code, if it after a trip to the dealer to sort out this code turns up nothing (no other stored codes) then there may be a problem in the TCM (Transmission control module) so u should get this to the dealer and have them read the codes and report them to u.

It is possible that there are other causes, but if you just want to replace the output speed sensor:

it should be easy enough to find. it will be along the tail shaft pointing perpendicular to the drive shaft. It will have two wires for a harness. simply unplug the sensor, put a drop pan under it in case some fluid drops out. then just wrench it out, install the new one and hook everything back up. check fluid level if applicable... good luck

    what i mean by "other causes": it is possible that its a wiring issue. It is possible that there is a short in the wiring, or (on extremely rare occasion) a computer problem. I've had to replace more of these speed sensors than i can count, so i would anticipate just replacing the sensor is a safe bet.

  • Corey Morgan May 14, 2009

    i just read this again... emissionwiz is right about the PO700 code... the reason is this.... the engine and transmission set codes separately. they can be scanned separately as well. when the transmission has a problem, its system sends a generic message (PO700) to the engine system. HOPEFULLY this will tell the tech to check the transmission system with the scanner. if your output speed sensor info is correct, there should be a code in the PO720-PO723 range, all are output speed sensor related, but some specify intermittent or no signal or what have you

  • Corey Morgan May 14, 2009

    that would work. You might have to drive it for a while with the new sensor to make sure the code doesn't set again. best of luck to you

2004 Durango dies and shifts weird

I will try to help..ihave a 2000 dodge durango with the 4.7 v8..My trans started shifting funny and the rpm's would go up to 2000+rpm when i was driving, which means i was getting really crappy gas mileage at 40mph..took it to shop, engine light on,put it on machine to a generic p0700 code plus a couple others..code basically says tranny is fn up..
Try this a cheap fix first that worked for me..on the transmission,driver side there are two sensors..input/output transmission speed be exact..they send info to computer to regulate shift points in trans..upshift and downshift..replace them both although one may be the culprit..cost at the dealer here in Delaware was $40.72 for one..there is one bolt(8mm)and one electrical connection to each..time to replace both about 15minutes you don't even have to jack up truck but you will have to get underneath.

Hope this helps and good luck..if you change them and find the tranny shifting properly..cycling the on and off switch will eventually turn off the engine light..just drive it normally i mean..go here shut it off..get back in start it up and will go out..good luck

I have a 2000 plymouth voyager with error codes P0700,P1782,P0731, and P0755 and have no clue how to repair or how much repair is Can anyone help out?

speed sensor most likely this transmission runs 2 an input and an output. if your speedometer is fluctuating or not working it would be output problem if not probably an input speed sensor. these sensors can be purchased for around 40$ i believe at your local dodge/chrysler dealer.

replacement is fairly easy. open hood remove air cleaner locate the sensor on the transmission. in put is closet to engine. unplug sensor remove by unscrewing it. reverse for installation. disconnect battery for 2 min to clear codes and road test

Check engine light code P0720...failed output shaft speed sensor or electrcal problem...what is a speed sensor..can i buy the part

The output shaft speed sensor lets the computer know how fast you are going down the road to help it pick gear change points..
Yes, you can buy one and replace it.
First check the wires and plug going to it.
Your manual will probably describe its location better than me, but it will be toward the rear of the gearbox and usually has a small gear on the end that meshes with a mating gear on the output shaft as you put it in.

Why is my engine light on on my 2000 Dodge Durango?

you need to put your key in the ignition turn til dash lights come on dont start engine then turn it off ,do this 3 times leaving key in the power position on the 3rd time, watch your speedo and check the codes . p0700 is a tranny problem,you dont need to get it scanned at a dealer unless you need to 95% it is the speed output sensor 5 minute fix under 100 buks do it yourself. any other code check it and go on the internet cuz alot of people get ripped off and its a simple cam sensor , crank, abs, speed,etc....

Dodge Durango 1998 5.2L Output Speed Sensor code P0720 Location

Its in different locations depending on if its 2wd or 4wd. For 2wd its in front of the drice shaft or for 4wd its in the tranfer case, just look for a white shape like box with wires plugged into it and you need a socket to remove it, iam not sure how much it is to replace as the cost varies at different shops.
