BleacherBum Posted March 1, 2020 Share Posted March 1, 2020 I had a check engine on my 14 S Hybrid that came back with P26CA & U019F as the 2 top results when scanned. After some research all signs point to the electric coolant pump (DS7Z8C419D, PW611, & PW544) and its harness connector. Of the limited amount of info I've found on google and YouTube, i cannot find anything that shows where this is located. Does anyone have experience with this? 0 Quote Link to comment Share on other sites More sharing options...
Xeis2018 Posted February 4, 2021 Share Posted February 4, 2021 Just found this thread. Im tripping the same error code on a 2013 ford fusion hybrid. P26d0, P26ca, U019f. Im only seeing a ref to corrosion on connectors. Specifically C1812 0 Quote Link to comment Share on other sites More sharing options...
Xeis2018 Posted February 4, 2021 Share Posted February 4, 2021 Some 2013-2019 Ford Fusion/MKZ vehicles built with a 2.0L HEV/PHEV engine may exhibit multiple drivability or electrical concerns with one or more DTCs. The most common are P26C3, P26CA, P26D0, P2800, P2802, U019F and U0284. Inspect the connectors C146, C1651, C1812, C168C, C1717 and C134 for signs of water entry or corrosion. 0 Quote Link to comment Share on other sites More sharing options...
leitey Posted October 31, 2021 Share Posted October 31, 2021 I am also having this issue. 2105 fusion hybrid. Multiple codes showing loss of communication with the engine coolant control module. Everything I've found points to corrosion on connector C1812, which is on the water pump. Did anyone ever figure out where the water pump or this connector was located? 0 Quote Link to comment Share on other sites More sharing options...

drolds1 Posted November 1, 2021 Share Posted November 1, 2021 (edited) From my limited knowledge about FF Hybrids, it's located under the back seat. There's a better likelihood of getting a more detailed answer to your question on the fordfusionhybridforum. Coolant pump and its harness.

leitey Posted November 1, 2021 Share Posted November 1, 2021 Just following up on this: The water pump is mounted to the fan shroud. So the very front of the car, behind the radiator. It's at the bottom, on the driver's side. Connector C1812 sticks out the bottom of it. Just had to remove the front half of the felt underbody cover, and it's right there, just above the metal bar that the felt mounts to. Unclicked the tab on the connector, sprayed it with contact cleaner, let it dry for a second, plugged it back in, and all 3 codes cleared. 0c0ba673-8524-4034-b032-b567aa8a21e7_coolant_pump.pdf 0 Quote Link to comment Share on other sites More sharing options...
Dendron01 Posted February 26 Share Posted February 26 (edited) The electronic water pump on my 2014 Ford Fusion Hybrid was found near the passenger side right behind the radiator shroud and above a black bar. It's a cylindrical shape most notably found with a blue plug on it's side. Going based off what my ford dealership had said, should you clean the plug, dry it, and apply di-electric grease, should be good enough to reestablish a proper connection and clear those codes. However should those codes come back after clearing with an Obdii, the codes may arise from a faulty water pump. The part # for these pumps may vary. As i'd found PW-544 and PW-611 to look very much the same, with the same prongs for connection. Though from what carservicepro (youtube: @carservicepro P26CA, Coolant Pump, Hybrid, Ford,Fusion, Electric short, coolant Pump fuse location ) had said, before you'd go off to buy a new pump should the wire connection not be a problem, could also check fuses for any faults.
