Expedition Weak Battery Sensor

Hi, I'm having some trouble with my 2016 Ford Expedition (gasoline engine). At 118104 km, I've noticed a weak battery when starting, along with flickering lights. Suspect it might be a bad battery sensor. Any ideas on how to confirm?

A 2016 Ford Expedition owner experienced a weak battery and flickering lights, suspecting a faulty battery sensor. A suggestion was made to test the sensor output for inconsistencies. Following professional diagnostics, it was confirmed that the battery sensor was defective, leading to its replacement.

I encountered similar symptoms with my 2018 BMW 5 series. The voltage sensor was defective, causing erratic battery behavior. Have you considered battery testing, specifically focusing on sensor output?

Thanks for the tip. When you say 'sensor output,' what specific values should I be looking for during the battery test?

In my case, the voltage readings from the sensor were inconsistent and often lower than expected. I would strongly recommend professional vehicle diagnostics to determine if the sensor is defective.

Thanks. I took it to a shop as you suggested and they confirmed it was indeed the battery sensor, repair cost was 315€. Appreciate the insight!
