Do I have to replace this electric pump?Yes you need to replace it. I think that is the one that provides lubrication for the transmission in EV Only mode.Do not drive in EV Only at high speed with that pump not working.Your English is better than a lot of native English speakers.

murphy Posted November 19, 2019 at 11:51 AM Report Share Posted November 19, 2019 at 11:51 AM Does it mean that gasoline engine starting in order to lubricate? Are there two kinds of ways lubricate - mechanic and electric?Yes, in EV Only the engine is not running and can't provide lubrication. Lubrication is provided by an electric driven oil pump. If the electric driven oil pump has failed you are risking the transmission. My engine hasn't run for months at a time when it is warm outside. The Hybrid does not have this pump because the engine is only off for about a mile before the small battery needs to be recharged. jj2me 1 Quote Link to comment Share on other sites More sharing options...
alvarokr Posted November 19, 2019 at 02:25 PM Author Report Share Posted November 19, 2019 at 02:25 PM Ok, I have to buy a new pump. Thanks for your help Quote Link to comment Share on other sites More sharing options...
alvarokr Posted November 20, 2019 at 02:03 PM Author Report Share Posted November 20, 2019 at 02:03 PM I made a small test today. I pulled out the plug from electric pump. Then I goes a few km/mil. The MIL didn’t light up until second start :/ Maybe this pump starts when an oil of gear have higher temp. Where is other pump which runs while work of gasoline engine ?

murphy Posted November 20, 2019 at 05:30 PM Report Share Posted November 20, 2019 at 05:30 PM I assume the engine oil pump is inside of the engine and directly driven by the engine. Quote Link to comment Share on other sites More sharing options...
alvarokr Posted November 20, 2019 at 05:44 PM Author Report Share Posted November 20, 2019 at 05:44 PM It is obvious that gasoline engine has pump inside, but there is other pump to transmission apart from the electric pump? Quote Link to comment Share on other sites More sharing options...

16vjohn Posted December 30, 2019 at 05:27 AM Report Share Posted December 30, 2019 at 05:27 AM If you have less than 100,000 miles on your car, that pump may be covered by the hybrid parts warranty which expressly covers the transmission. Call your local Ford dealer to clarify. Quote Link to comment Share on other sites More sharing options...
Ron Posted October 28, 2022 at 11:20 PM Report Share Posted October 28, 2022 at 11:20 PM Hi @alvarokr, Can you tell me if the procedure worked or you did replace the pump? Best regards, Ron Quote Link to comment Share on other sites More sharing options...
