So this last week my wife’s Prius had the check engine light (as well as a few other lights on the dash) pop up as she backed out of the driveway. Car is a 2012 with 200k and for what it’s worth it was 98 degrees out when it happened. I got home yesterday and scanned the car and am seeing P0A80. In other post I have seen people who get this code usually also get a message check hybrid system or something of the such pop up but hers never did that. I tested the 12v and it tested 12.42v. I cranked the car and it ran for awhile all like normal and the meter on the dash showed that the hybrid battery was indeed charging up while the engine ran. I took a few screenshots in Dr Prius hoping it would be of some benefit. The numbers seemed to fluctuate so I posted a couple. I plan to plug up techstream tomorrow to see if it can give me some more info. The car still gets good gas mileage and I have a prolong hybrid charger but have never used it on this car. Can anyone tell from these screenshots if there are any problematic cells that needs to be replaced first before using the prolong?
