Check Engine Light On problems of the 2015 Ford F-250

At just over 100000 miles, check engine light code p20ba came on, reductant heater, turn out as it is an f250 its not covered, but f450 and f550 are. Also as air temperatures are in high 80f, the heater is not required. Now emissions are not meeting the specifications and truck completes more regens to stay clean, increasing chance of heating nearby items (straw, grass and household structure) potentially starting fires. The regens occur during highway travel and the heating affects surrounding area when parked.

I was heading from cibolo, TX to kingsville, TX. (distance 181 miles) upon arriving at destination I shut down my truck. After approximately one hour, I started my truck and the check engine light came on. I connected my obd reader and it identified the fault code p21b0 (I did not clear any codes). From my research it relates to the �reductant level sensor �c� circuit high�. After researching more information I started looking through the information center under the vehicle setting and noticed the def level was below half (I never got a pop up or notification from the information cluster). In the past the information cluster would display the level notification without an engine light coming on. This time it did not. I purchased some def and filled the tank. It only took two gallons of def. The engine light remained on the rest of the day driving around after filling the def tank and the def �below half� notification also remained on. The next morning I started the truck and the engine light was off and the def �below half� notification was gone.

Since my last complaint this truck has had to have the def heater/sending unit replaced @ 70091 miles. Today the check engine light has come on again for the 4th time for a p207f code. Purchased truck October 2018 with 53,000 miles. December 10, 2018 ccv collar put in @ 57,104 miles for p207f code. December 21, 2018 nox sensors replaced @ 57414 miles for p207f code. August 30, 2019 egt sensors replaced @ 65687 miles for p242a & p2031 code. January 15, 2020 nox sensors replaced @ 69332 miles for p207f code. February 4, 2020 def heater/sending unit replaced @ 70091 miles - code ??. March 8, 2020 truck has popped p207f code again @ approx 70600 miles. At all times the truck was moving when the check engine light came on. At all times the truck was taken in for service within a few days of the check engine light coming on.

Tl- the contact owns a 2015 Ford F-250. The contact stated that while driving at an unknown speed, the check engine warning light illuminated. The contact then ran a code on the vehicle and the diesel exhaust fluid reluctant heater appeared as the defect. The contact spoke with two independent mechanics and a dealer(phil long Ford at chapel hills 1565 auto mall loop, colorado springs, CO 80920 844-234-1769) where he was informed that there was a recall placed on the vehicle for this issue; however, his VIN was not included in this recall. A search was conducted to find this recall but no results were found. The manufacturer had been notified of the matter and transferred him to the NHTSA. The vehicle had not been repaired. The failure mileage was 59,000. Jo.

Bought used f250 October 2018 with approximately 55,000 miles. Went into shop for p207f on 12/10/18. Installed ccv collar kit and reprogrammed pcm @ 57,104 miles. 12/24/18 truck back into shop for p207f code. Nox sensors replaced @ 57,473. In January 2020, check engine light and limp mode message displayed. Nox sensors replaced again for p207f code on 1/17/20 @ 69. 700 miles approx. Nox sensors only a year old. Per mechanic, catalytic converter is suspect - but is on indefinite back order with Ford. 1/24/20 while traveling down the road @ 60mph the truck started the "death wobble". Truck back in shop, bad track bar replaced. Wheel damper needs replacing, but this part is also on indefinite back order.
