Ok, So I posted on another thread but no one looked at it so Im making another one. Im getting code 12 and 23 popping up on the check engine light.
Code 12- Direct battery input due to PCM was disconnected within the last 50 key-on-cycles
Code 23- Intake air tempature sensor input is above or below acceptible voltage.
I dont exactly know what its saying. So is it the battery thats causeing this or just the IAT sensor that needs to be replaced? I honestly have no clue where to start to even fix this issue and any help or ideas of whats causing this would be awesome. Thanks.
