My daughter-in-law's 2013 Ford Focus SE started experiencing hesitations and slow/no acceleration. As she was driving, the car suddenly would not go above 30mph and the "check engine" light illuminated. OBD codes P2831, P2832, and P287b are present. She is the 2nd owner and the car only has 56,000 miles. The Transmission Control Module (TCM) appears to be the issue and the replacement should be free under Ford Customer Satisfaction Program 14M02 (10yrs/150,000miles). Ford issued a "Manufacture Communication" about this very serious safety problem instead of a Recall, which is why she was not notified of this dangerous problem. The "warranty in service date" on this car is March 2013 which…
Shift fork calibration not learner #P287B . .Shift Fork A Position Circuit Range #P2832.. Shift Fork A Position Circuit #P2831
WHEN I WENT TO WARM UP MY CAR THE CHECK ENGINE LIGHT IS ON AND THE TRANSMISSION DOESN'T WORK RIGHT. IT TAKES A WHILE TO ENGAGE THE GEAR AND WON'T GO PAST 30 MPH. IT SHIFTS VERY ROUGH. IT HAS BEEN DOING THIS FOR A WHILE NOW EVERY TWO DAYS NOW. I HAVE DONE THE TCM ADAPTIVE LEARNING SERVICE IN FORSCAN AND I HAVE UPDATED THE PCM AND TCM AND ABS MODULES TO THE LATEST CALIBRATION. AFTER THE TCM ADAPTIVE LEARNING IT SHIFTS FINE BUT THE DTC'S WILL COME BACK ON IN A FEW DAYS. THE DTC'S ARE P2831, P2833, AND P287B. I DON'T KNOW WHAT ELSE TO DO? THE BATTERY AND BATTERY CABLES ARE FINE.
THE TRANSMISSION DOESN'T SHIFT RIGHT AND THESE DTC'S ARE PRESENT. P2831, P2832, P287B. I HAVE RAN THE TCM ADAPTIVE RELEARN SERVICE AND THESE WILL COME BACK ON SOONER OR LATER. I HAVE MAINLY BEEN ONLY WARMING UP MY CAR AND THEY WILL COME BACK ON SOMETIMES IN A FEW WEEKS. I HAVE CHANGED OUT THE NEGATIVE BATTERY CABLE DUE TO CORROSION AND I'M NOT SURE WHAT TO DO NOW? IS A TCM MODULE UPDATE NEEDED?
…TOWED THE CAR TO THE MECHANIC THE NEXT DAY AND THEY RAN A DIAGNOSTIC THAT CAME BACK WITH 5 ERROR CODES INCLUDING: P0805, P087A, P2831, P2836, AND P2861. A PIN POINT TEST WAS PERFORMED AND FOUND THAT THE VOLTAGE WAS AT A CONSISTENT 5 VOLTS, SO THEY CLEARED THE CODES AND TOOK THE VEHICLE FOR A TEST DRIVE AND IT WAS FINE AGAIN. THE VEHICLE HAS ABOUT 79,000 MILES. ATTACHED WILL BE THE MECHANICS FORM ALONG WITH WHAT THEY SAID ARE SEVERAL CODES FOR RELATED RECALLS THAT WERE SUPPOSEDLY ALREADY FIXED. *TR
…THE CHECK ENGINE LIGHT WAS ON WHEN I EXPERIENCED THE LOSS OF POWER AND CODES P2831 P2832 & P287B WERE PRESENT. THE MECHANIC SAID THE "MECHANICAL MECHANISM" IS "STUCK" KEEPING THE CLUTCH APPLIED. HE MADE THIS ASSUMPTION WITH THE TRANSMISSION STILL INSTALLED & NOT CHECKING THE INTERNAL COMPONENTS; HE MUST BE PRETTY DARN GOOD TO DO ALL THAT! HE CHECKED THE TCM PER NOTIFICATION 14M02 WHICH SURPRISING PASSED. TO THE BEST OF MY KNOWLEDGE NOTIFICATION 14M01 WAS NOT CHECKED WHICH WOULD REQUIRE THE TRANS BE REMOVED FROM WHAT I READ. TSB 15-0121 ALSO CALLS OUT A POTENTIAL CAUSE. THEY WANT ME TO PAY $2500 TO REPLACE THE CLUTCH JUST TO BE ABLE TO FURTHER DIAGNOSE POTENTIAL PROBLEMS WITHOUT FULLY…
NEW 2012 FORD FOCUS B/C I DIDN'T WANT USED CAR REPAIRS. AT 57.2K MILES THE TRANSMISSION STARTED TO MAKES NOISES, AUTOMATICALLY SHIFT ON ITS OWN SOMETIMES TO A CRAWL, ROLL BACKWARDS & LURCH FORWARD WHEN STOPPED AT LIGHTS/STOP SIGNS, NO POWER UP HILLS. THE AUTOMATIC TRANSMISSION COST $1,000-$1,500 DOLLARS BUT IT DRIVES LIKE A CLUTCH. MY MECHANIC TOLD ME FORD EXTENDED THE TRANSMISSION WARRANTY TO 7 YRS OR 100K MILES B/C OF THIS. HE GAVE ME A COPY FROM HOTLINE ARCHIVE 1) FIRST PERFORM THE TRANSMISSION ADAPTIVE RELEARNS USING THE FACTORY OR EQUIVALENT SCAN TOOL 2) IF THESE CODES ARE P2831 AND/OR P2832 RETURN IMMEDIATELY, IT IS LIKELY THERE IS AN INTERNAL CLUTCH ISSUE. NOTE, THERE IS A COMMON…

What should I do if my car shows P2831?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
