I have 2003 Prius That Has P3191 P3060 Codes and won’t reset I had the battery replaced only once by a company that went out of business it was Prius hybrid repair in Annapolis MD back in 2014 Back When I had P3006 P3028 Codes in 2014 any ideas how have to fix P3191 P3060? It Had Miles 188K Miles Back In 2014 When The Battery Was Replaced And Now It Has 380,899 Miles.
It would appear that you have two separate issues here! For the P3191, take a look at this: Try cleaning it with MAF Cleaner (Only! Accept no substitutes!) before you go to the expense of buying a new one. For the P3060, look at this thread: 02 with p3060 code. Temperature | PriusChat
Well generally the fan running in the back and a generation one or two means something is a miss or the battery ECU thinks something is amiss in that area or in some area and it has the fan on because it thinks it's possible that the battery might be getting very warm or something of that nature generally when this happens in any of the four generations that I have and I start looking under the hood of the battery I see the problem very quickly corrosion frosting on the nuts you know sometimes leaks in between middle rack modules. Things like that and then you're on an adventure to clean up and sort out the battery don't forget the battery control ECU the orange plug all of that your battery ECU may be different than mine but a similar process I would imagine making sure it's clean the receptacle has all the pins in it that sort of thing the stuff goes a long way in your journey
The second link in post #3 for the P3060 code is a good one to read. The description for the P3060 code is described in post #6 of that thread. The first link in post #3 is not a very good resource for the P3191 code. The description of the P3191 code is "Engine does not Start". There are many things that may cause the engine not to start. The mass air flow (MAF) sensor is only one of the many things to check when the engine does not start. So my question is, does your car start, and are you able to drive the car? PS: Please use punctuation (peroids) in your posts. It makes it much easier to read.
