2008 Honda Civic hybrid battery
 

Bad IMA battery? So I bought a 2008 Honda Civic hybrid it had check engine light and an IMA light on. I changed my spark plugs and coils and all lights have gone away? The battery is still reading low but charges. Should I be worried? The only light that is on now is tpms.

If the car sat awhile, the individual tap voltages may have drifted out of spec triggering an IMA light, but running the car regularly can counteract this.

If you cleared codes or disconnected the 12V, codes were wiped and won't return

Does your battery gauge ever behave like this?


Worth clicking the two timestamps in the description as that's the behavior.

Essentially, the gauge "marches" up or done about 1 bar per second.
