Output Speed Sensor Circuit Range/Performance

I received a recall notice on my F150 and took it to the dealership for repair even though I have not had any check engine lights or codes on my vehicle. 20 days After taking my vehicle to the ford dealership for the 24S37 recall on the OSS while driving on a two lane back road my truck experienced a hard downshift immediately followed by a check engine light. I lost all acceleration and had to coast to a safe place to pull over. I connected a code reader to the vehicle and immediately got a P0721 code for output speed sensor. I had the truck towed to the dealership and was told they drove it and could not get it to repeat the issue. The dealership only drove 2.9 miles while the had the…

My car had 78,530 miles on it when the rear differential binding causes shuddering/thumping during turns, which risks sudden wheel lockup or loss of control on sharp turns or low-traction surfaces. Please Note that Mercedes-Benz acknowledged this issue in TSB LI35.31-P-072105 but has not issued a safety recall. Dealer Diagnostic & Repair: Dealership confirmed a total component failure of the rear differential. The entire rear axle differential assembly (Part #A1763503100) and related hardware had to be removed and replaced. Total cost for rear axle replacement alone was $7,541.30.

…The vehicle was scanned by a local independent mechanic who retrieved DTC: P035413, A10D, P072102, U016886, V1FBD04, 94C3, V1DAV54, V1DBD31, P030085, and V142E31. The manufacturer was made aware of the failure. The failure mileage was approximately 88,000.

…Error codes P0721 and P0722 were found, which would seem to apply to the recall. Supposedly the dealership was told that the truck was too old (2014) and and the mileage was too high (102,000) to cover the repair (although, this is a fairly recent recall). Ford customer service told me that the recall only covered the update, not any repairs to fix the underlying problem. Ford will not reimburse me for any of these repairs, but they appear to be related to exactly what the recall was for. Curious what the NHTSA's opinion is. I believe that I put in a complaint with NHTSA for this issue when it first happened. Thanks for your time.

While driving at highway speed of 55mph, the vehicle went into limp mode. Large gear icon came on the dash, speedometer went out as well as mileage indicator. The vehicle lost almost all power and started to slow rapidly. Pressing all the way down on the gas made the truck go maybe 30mph as a guess. This was a very dangerous situation as there was no where to pull over and cars were coming up behind me quickly. I finally was able to get off an exit ramp and pull over. After restarting the vehicle it moved properly. I scanned the vehicle and received the output speed shaft sensor fault code P0721 and P0722. There is a recall for this problem, but since I proactively brought my truck into Ford…

Experience hard shifting, loss of power/acceleration, and malfunctioning instrument cluster including speedometer and digital display when accelerating. Scanned error code is P0721. Problem may be related to Customer Satisfaction Program 19N01 (molded lead frame) that has expired for my vehicle which has 193,000 miles. Ford is no longer covering the repair which is a safety hazard for its vehicle owners. Loss of power, inability to accelerate when necessary, and controls that don’t work put me and my passengers at risk. Dealer has confirmed that the problem is most likely due to expired repair but states it is no longer covered by Ford. I do not recall receiving a letter for this problem and…

My 2013 F150 downshifted abruptly from 5th to 1st gear going 55. This caused me to stop dangerously and abruptly. It then got stuck in 1st gear. I turned off truck and restarted and it was stuck in 3rd gear. I did have a check engine light read which were codes: P0720/p0721/p0720 pointing to the output shaft speed sensor. I had Ford dealership TSB performed in 2020 to reprogram PCM to prevent this from happening, wrench icon showed a long with airbag light and dashboard quit working all except RPM gauge. The first time this abrupt downshift occurred was today February 21, 2024. Seems like a very dangerous safety issue and the dealership has no regards to it and said they are booked out and…

…1) P0721 Output shaft speed sensor circuit range/performance. 2) P07210-00 and 3) P0722-00. Took it to Ford dealership and said it was a "customer satisfaction recall" but my truck is past the 10 year period being a 2013 model so it's not covered and will be $1,300.

The Output Speed Sensor has been failing multiple times since I had the recall remedied in September 2021. The codes p0720, p0721 and p0722 have been present, and it hadn’t been to much of an issue until it downshifted to first gear while going 60+ mph, causing me to temporarily lose control. Because of the downshift the engine redlined causing the 8th valve to fail. The dealership says I need a new engine and refuses to fix the transmission because my truck has a salvage title. They also claim that they can’t confirm that the transmission caused the engine to blow. They have since been giving me the run around. The salvage title was present when they did the remedy in September but now it…

…the plug block on the transmission said it was leaking that didn’t fix the problem then I took it back a week later and they said they couldn’t get it to do anything wrong now three months later it is starting To happen more frequently had code check P0721 Said it was the output shaft speed sensor can anything done to fix the problem . So I don’t have to keep spending money when I take it to the dealership where I bought the truck in August 2020 it came with a two-year bumper bumper warranty
