Ford Transmission :: 1998 F250 - Code P0720 For Output Speed Sensor Circuit - No Reverse
Dec 27, 2016
I bought late 98 F-250, 5.4 G, 4WD. OHad to replace the steering flange because they messed up the ignition cylinder and flange. Truck didn't run for 4 years. 249K miles, no history available. Got the engine running, no DTCs. D, 3, 2, 1 barely moved the truck forward but, R hauled butt in reverse. Checked transmission fluid it was good and clean.
Came back to it a few days later it threw a P0720 (output speed sensor circuit) and I have no reverse, park feels like it wants to move, R is neutral, N is forward, D is forward, 3 is forward, 2 is forward, 1 is forward. The N is full drive. I cleared the P0720 code after it came up and it has not returned. The instrument gauges work but the odometer display is intermittent. Linkage? Fluid? Sensor? Wires?

Okay, I have a P0720 code. I bought the Output Shaft Speed Sensor and read that it is on the back end of the transmission.
Need to confirm that it is on top of the transmission, near the tail end? Why are parts that go bad always in the most inconvenient places?

I just replaced my starter and on my first ride after replacing it the X started to stumble a bit, and then would stall out at almost every stop light. It threw a CE light and I pulled the code P0720. I searched here and it seems most guys say this is a C.O.P. issue. If it is a bad C.O.P. would it stall like that?
I did have the battery disconnected but I made sure the terminals were clean and tight. Is this a coincidence or did I do something while changing the starter?

My hyundai 2004 sta fe awd 3.5 LX engine light came on while cruising dwn the freeway. At the same same time i heard a loud thud and speed went down from 65 to 40mph and a high idle. I drove it home and hook up the obd2 scanner and got P0720 suggesting bad output sensor. So I decided to buy new sensor from the dealership, put it in and thought it will fix the problem. After few days the engine light came on (P0720)again with the same clunk noise and speed down from 65 to to 40 mph at high rpm. Took it home, did some experiment by putting back the old sensor. I Connected the harness back, but this time I wrap the female connector with the electrical rubber tape and electrical vinyl tape. Problem fixed. No more engine light,transmission shift smoothly. I think the connector (harness side) to the output sensor was crack that's why its not making good solid connection. The rubber tape technique held the female connector pins tightly together. New part didn't do anything but it was a learning experience.

I had a rebuild done on my 2002 Accent. My question is now we get a code for the output shaft speed sensor. Would this have been replaced as part of the transmission rebuild?

I have a 2007 f150 sport. I am getting a 24 code on the airbag light and I do know that is Sensor output feed/return circuit open. What I do not know is where is this sensor located and what could it mean if I am getting the code...

I just recently purchased my first mk4 golf 2.0 after having a mk3 jetta vr6 for two years. I've been having problems with the car shifting (automatic) i put a code reader on it and came up with p0722 output speed sensor which explains why it sometimes shifts at 4500. My two questions are where is the output speed sensor located? and what is a normal shifting range for properly running automatics?

I just bought a '98 Ranger 2.5l 2wd. After driving it for a week or so I got a P1405 Code. After a quick google search I got :
P1405 Ford - DPFE Sensor Circuit Upstream Hose
Possible Causes: - Faulty Differential Pressure Feedback Electronic (DPFE) sensor (EGR pressure sensor)
- Plugged or damaged EGR tube
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection
Now, I have done my research between forums and youtube and have found this EGR system to be quite. I've gone ahead and replaced my DPEF. I took an air hose and blew out all the small lines coming into the DPEF. I still have the engine light. My next move is to get a volt meter and see if I'm getting power to the sensor.
My question is about this particular code and is it possible I need to look farther into this EGR system (EGR Valve, EGR Hose, etc.)

2004 Sport Trac V6. Been having hard shifting and P0715: Input/Turbine Speed Sensor Circuit. Cleared the codes and still returns.
From my searches, readings and looking at the parts diagram. On the newer 5 speeds the sensor is the one on the inside of the tranny. This requires taking the entire tranny apart? Is there an external connector for the sensor that I can check or clean first? Replace this sensor. I know the older ones were mounted on top of the tranny. I think this one is mounted on the inside though.

The check engine light came on in my 1997 Honda Accord and the OEM diagnostic says it's PO501 which is a performance problem in CVT speed sensor circuit. My mechanic is on vacation. Is it safe to drive short distances until I can have it fixed?

I have a 2007 f-250 6.0 liter turbo diesel. I was pulling a trailer with a golf kart on it and was not in tow haul. I was going up a hill and it shot up into 5th gear. I pulled into my house and shut it off and refired it and it acted fine. I went on a little test drive to see if it was going to do it again before I went on my trip. As soon as it shifted into third gear the tow haul light started to flash on my dash and went to 5th gear and would not down shift even if I did it on the column.
I scanned the truck with my snap on modus and it gave me these codes. P0706-transmission range sensor A circuit range/performance, P0707-transmission range sensor A circuit low input, and P1702-transmission range sensor circuit intermittent. I put a transmission harness in it and started it up and it ran fine and the codes were gone. I went for a test drive around the neighborhood and as soon as it hit 3rd gear it did the same thing as before. Today I put the old one back in and checked the codes so I could write them down and there weren't any so I went for a drive and it shifted through all the gears great and downshifted fine as well.
I pulled into my drive way to check for codes once again and there weren't any. I was gonna go for a ride in tow haul to see if it would do it and as soon I put the truck in reverse it started to idle high and the tow haul light started to flash again. I put it in drive to pull back into my drive way and it immediately shifted into 5th gear and threw the same codes...

I recently picked up a 2005 f250 SD 5.4 4x4... I was having issues with sporadic shifting and wandering shifts while cruising around 100kph, scanned it and came up with p0721 OSS sensor circuit performance fault.
I checked the harness and all looks fine, now I attempted to remove the OSS at the rear of the tranny, got the 8mm bolt out however could not, for the life of me get the sensor out. I tried not to use pliers to twist the sensor or anything for fear of breaking the sensor off and having bits go into the transmission.

This is what I get from the DTC .....
DTC P0705
Description : transmission range sensor circuit malfunction
State : History
I have done some google search on the above diagnostic trouble code P0705 and as i understood , it indicates that the Engine Control Module (ECM) has received an input error from the Transmission Range Sensor (TRS).
Since the check engine light illuminated two times (two separate occasion) then it turns off now; the ECM is actually receiving input signal from the TRS.
So that leads me to think that the TRS is actually working but the problem might be one of the following two:
1- Open or short in the TRS circuit?
2- Dirty transmission fluid.
What do you think the steps i should do first of all ? how would i check the transmission fluid since my vehicle has no transmission fluid dipstick. My driving condition would fall into "severe" category and it reached 60,000 miles now ...

The MIL light came on and I noticed the shifting P-D or P-R was hard. Checked the Transmission Fluid and noticed it was low. Topped it up, but still MIL is on and shifting hard still. I bought a OBD2 Scanner and it returns P0707 "Transmission Range Sensor Circuit Low Input". Should I try clearing the DTC? It's a drag because it's my wife's car and she's driving mine.

Long time Ex owner. This is my second 2000, 4wd, Limited, 6.8 V-10. Just bought this one last month and after two weeks of local driving the following problem showed up:
1. Week of July 5 through 11: With vehicle cold (65*) started and placed in reverse to back out of garage. After slight movement engine stalled like a locked up torque converter or turning ignition off. CEL illuminated. Turned off ignition and restarted. Again in reverse had same stall. Third time no problem but CEL still on. Code is P0720 using "Actron Auto Scanner."
2. Erased Code P0720 (OSS circuit malfunction) and P0307 (Cyinder 7 Misfire Detected). Drove car approx 20 miles without incident. No stumbling, no vibration, no detectable misfire, shifts okay, speedometer okay.
3. Next day with vehicle cold, started to back out of garage and stalled with CEL illuminated and O/D light in shifter blinking. Recycled ignition, started and no O/D light but CEL still illuminated. Vehicle did not stall. Checked code and P0720 set.
4. Replaced OSS on tail shaft of transmission. Same stalling problem with P0720 set.
5. Replaced #7 COP w/aftermarket type to test possibility of bad COP because of earlier P0307 DTC. Same problem exists, first start of the day the vehicle will stall as soon as it starts to move in reverse.
6. Replaced rear ABS sensor. While doing so noticed the ABS sensor wire harness was rubbing the tailpipe and the split, wire conduit was partially melted. Inspected wires (2) within and both appeared okay. Safety wired the harness away from the tailpipe.
7. Let the vehicle sit awhile. Outside Air Temp 84*. Started, placed in reverse, moved a couple of feet and engine stalled and O/D light on steady. Recycled ignition and started again, backed out with no stall or warning lights. No CEL on. Drove 10 miles without incident.
8. Allowed vehicle to cool, started and attempted to back out of garage. Engine stalled, CEL illuminated and O/D light flashing, code P0720.
9. Sunday morning 12 July: 71*, Allowed vehicle to idle in P in garage for 10 minutes before trying to back out. Vehicle did not stall. CEL still on from previous day, no O/D light. Erased P0720 code. Vehicle operating normally.
10. Sunday Noon 12 July: 85*, Started, placed in reverse, backed out and no stall or CEL or O/D light.
After considerable research online at ford-trucks.com found P0720 is a common problem but not easily diagnosed. In most cases the gremlin is COPs and or deteriorated plug boots but in this situation the engine appears to run smoothly and the failure/errors only show up when the vehicle is moved in reverse gear after a cold startup. Once it stalls then restarted it runs fine.
Made a quick check of alternator for failed diode using DVM since I don't have a scanner. Checked okay for voltage and AC ripple. I do have an appointment on Wednesday with my local auto repair shop for troubleshooting. Will have them do continuity check between OSS and PCM and an AC ripple test. Does this sound like an electrical circuit problem or internal transmission problem? Want to make myself as smart as possible when I talk with the techs.

Just got the transmission rebuilt in my truck and other then shifting hard sometimes it has been doing great, Hooked it up to the goose neck this evening and everything was fine then went to back it up and pull it forward and after a short distance the od light was flashing and when i ran a check on it it was p0720? The transmission has less then 1000 miles on it?!?!? 1999 Ford F-250 7.3 Automatic....

Have the P1705 engine code (Direct Clutch Speed Circuit Fault) on 1996 Avalon.
I have removed it and trying to examine connectors and unit for problems.
Seems simpler to replace but cannot see spending the money on a crap shoot. Here is what I know:
Took voltage reading from each of the 2 connectors on the harness each with the key on but car not started. 1 probe to 1 connector and other probe to battery ground. Each connector displayed 0.76V.
Checked resistance across connectors on removed Sensor and it was 600+.
So...are these results determine whether the sensor is bad or the connector harness has an issue? Am I measuring incorrectly? Finally, is there only one of these sensors? I see on later models there are 2. Toyota P/N: 89413-08020

I have an 08 avalon w/ 281k miles. NEED to replace the transmission speed sensor (P0500 code thrown). Where is it located on the trans and what is the part #? I'm thinking about servicing the trans while I'm there but looks like a lot of "comments" regarding this transmission and the problems with servicing it!?

I am having a problem repairing my 1997 aerostar with a 3.0 engine. Code PO340 comes up. Ive replaced the cam sensor, cam sensor housing and the pcm. Using the diagnostic charts, I've thoroughly checked out the wiring, in the harness, at the sensor, and at the pcm. I've set the cam sensor housing at TDC with the appropriate timing tool. Code P0340 still comes up. I've seen a couple of other aerostars with the same problem. Ford TSBs .....

I have been having some engine/electrical issues with my 2003 saab 9-3 convertible. It started with the check engine light coming on I had it diagnosed as a map 2 sensor and transmission output sensor. The light went off and the car ran fine. Now the light is back on and the engine stalls out at random times (while accelerating, at idol, and now loses power during full throttle. It bucks on the highway).
Today while losing power blue smoke comes out of the tail pipe, but only during the power loss bucking. I also notice when there is a power loss or skip/bucking the turbo needle goes into the yellow/high mark. I am going to take it to a repair shop soon but what this might be? Also sometimes while driving when the bucking/skipping/power loss happens the gear indicator light on the dash goes from drive to neutral to reverse and park intermittently.
