Automatic Transmission Control Module Problems of Ford F-250

Hi. I took my 2021 f250 6,7 to the Ford dealership as it was having trouble starting, and just wasn’t running great. They changed the batteries, and told me it was a nox sensor. So I went and got my truck to fix the sensors myself; because they wanted to charge me close to 3 grand. The next day I got up, lo and behold it wouldn’t crank. I had to have it towed back to the dealership. I tested codes before I had it towed, and took a video of it not cranking. The following codes showed. P2291 pcm - injector ctrl press too low - engine cranking p2209 pcm - nox sens heater sense circ range/perf bank 1 sens 1 u029d pcm - lost comm with nox sensor a p2535 pcm - ignition switch on/start pos circ high u300a bcm - ignition switch it’s been in the shop a week , they called Friday saying it was starting, and there was nothing wrong with it. So I replied with all the codes, and told them there was definitely something going on. So they checked it again Monday and it wouldn’t start. Now today (Aug 5 tues. ) they say it may have a vacuum leak. Although non of the codes point to vacuum leak. I have no idea what to do now.

Check engine light comes on with injector codes. Ford clears the code and the problem continues to come back. Truck uses a lot more fuel when this is active. No help from Ford on getting this resolved. Issue: some 2020-2022 f-super duty vehicles equipped with a 6. 7l engine may exhibit an illuminated malfunction indicator lamp (mil) with cylinder injection pulse offset diagnostic trouble codes (dtc) p2b11, p2b13, p2b15, p2b17, p2b19, p2b1b, p2b1d, and/or p2b1f stored in the powertrain control module (pcm) after various fuel system repairs. This may be due to incorrect learned values in the pcm. To correct the condition, follow the service procedure to reprogram the pcm, reprogram the transmission control module (tcm), and perform the reset minimum fuel mass adaptions all cylinders.

The contact's husband owns a 2020 Ford F-250. The contact stated while her husband was at a stop sign, the transmission seized in 2nd gear and the vehicle failed to respond while the accelerator pedal was depressed. The contact's husband stated that the check engine warning light illuminated and "wrench" symbol was displayed on the instrument panel. On another occasion, the transmission seized in 7th gear and the vehicle was unable to make it up an overpass. The vehicle inadvertently started to roll back down the overpass. The contact's husband also had alerts on the Ford pass monitoring tool and received a “failure with pcm and 2nd gear bypassing during cycle" alerts on his cell phone. The contact drove the vehicle to a local dealer, where it was diagnosed with needing the transmission replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was unknown.

Tl-the contact owns a 2020 Ford F-250. The contact stated that when he starts his truck that when the vehicle switched gears the transition was rough. There are some times when the vehicle will remain stuck in a certain gear and then have a delay in shifting thus putting a strain on the transmission. When the contact used the vehicle to tow the issue was even worse. The dealer gene messer Ford lubbock 6000 west 19th, lubbock, TX 79407 (806) 793-2727 stated that issue may be with the pcm and ptm. They were going to check with the manufacturer and get back with the contact. The contact tried to call the manufacturer but the call disconnected. The vehicle remained unrepaired. The dealer reommended that the vehicle can be driven for now but not to tow anything. The failure mileage was 3,900. Tf.

Egt sensor fault resulted in a "stop safely now" alert, shutdown of power while approaching the neches river bridge in beaumont, TX, a bridge on a 3-lane interstate (I-10). Engine subsequently shutdown while in heavy afternoon work traffic causing high potential for a major accident. Traffic behind and next to me swerved and braked on the 75 mph interstate while the truck lost power as it just made the crest. Vehicle was towed. Egt was replaced. Bank 1, sensor 4. Second such failure. First was in August, 2015. Replaced with ac3z-5j213-b in Aug, 2015 (the current failed egt). This time replace with ac3z-5j213-c, see photo for differences in sensor design. I have read rq 14-005, vehicle commanded engine shutdown, and cannot believe this topic was revisited with no action resulting to require the 15v-175 remedy reprogramming for non-emergency vehicles. I ask the the NHTSA revisit this topic to consider allowing owners to have the same pcm change to stop a single egt sensor fault to result in an immediate loss of vehicle power and causing high potential for injury to the public. As a mechanical engineer in the petrochemical industry, and having participated in many hazards analyses over 20 years, I struggle to see that the consequence of continued use with a bad sensor for a longer period, but at some reduced power, could ever be greater the chaos, confusion, and high injury potential from prompt removal of 70% vehicle power from the driver in 45 seconds. Towing a 5th wheel trailer and experiencing the "stop safely now" power cutout is a recipe for disaster. Thank you for your consideration, and I hope to hear of the reopening of investigation on this topic and allowance to reprogram the pcm.

The consumer stated while driving at an estimated speed of 50-60 mph and attempting a forced down shift, the transmission shifted into 3rd gear instead of 4th gear causing rapid rear wheel deceleration and high engine rpm to occur. It occurred immediately following servicing of the pcm per the manufacturer's recall. The dealer advised the consumer to drive the vehicle up to 500 miles while the transmission re-learn its shift to points. After complying with the dealers request, the consumer continued to experience the problem.

2004 Ford f250 super duty king ranch. After reflash to repair an idle problem truck developed three very dangerous conditions. 1. Cruise stalled - going down hill at approx 55-58 the truck will stall without warning. No power steering or brakes. Reproducable on demand. 2. Downshift lockup - truck will lockup rear tires in excess of 30 feet if tow/haul mode is used. On first occasion it almost caused a major accident on highway, came within inches of a head on with a large dump truck while towing a boat. Reproducable on demand. 3. Coast stall. Intermittently stalls usually at off ramps after cruise has been released. Extremly dangerous to take offramps in such a large vehilce with no power.

The vehicle will lose power with the engine light coming on, cause unknown. The Ford dealership has had the vehicle for three days, stating that vehicle was getting some sort of resistance. The vehicle was again failing with the same problem. The consumer states that he had taken the vehicle to another Ford dealer and they seemed to have remedied the problem-linkage accelerator. The windshield was leaking-resealed-still leaking. The vehicle has been okay since the last repair. Now the windshield is leaking water, and is running behind the dashboard. The consumer has also experienced the following: when stopping the vehicle feels like the drivline shifts forward-loud bang,when starting off, the vehicle shifts backwards, the connector is not fully seated(pcm module), and the injector harness intermittenly opens-repair loose left valve cover injector harness connector causing high resistance cleared.
