Rljan Posted December 13, 2022 Share Posted December 13, 2022 Twice in the past two months, the car has hesitated when excelerating, followed by the check engine light and temperature guage showing overheating. The FordPass message says the system detected a fault with the high voltage battery coolant pump. After cooldown, the system returns to normal and after 20 miles or so the check engine light disappears. The dealer has no clue since the check engine light is no longer on. Has anyone experienced this problem or have a clue what might be causing this? Quote Link to comment Share on other sites More sharing options...
GaryG Posted December 15, 2022 Share Posted December 15, 2022 When a code resets on it's own, the problem cleared on it's own and the light reset. The fact when it happen was it possible it was hot outside? If the light happened when everything should have been normal, it may be a sensor.

Rljan Posted December 17, 2022 Author Share Posted December 17, 2022 It was actually cold the second time. The dealer replaced the coolant pump. Hopefully that will fix the problem. Quote Link to comment Share on other sites More sharing options...
