Can anyone tell me what code 12, 42, and 43 mean. I just replaced my plenum about a week ago and when i went out of town this weekend my CEL came on and gave me toughs codes.

 

Code 42 is "Auto shutdown relay control circuit indicates an open or shorted circuit condition"

Code 43 is "Peak primary circuit current not achieved with the maximum dwell time"

What that means, I have no idea.

Code 12 just means the battery has been disconnected within like 50 on cycles or something. I have never not had that one lol.

 

thank you! can anyone tell me what toughs mean though? i have no idea ether!

 

I have no idea what "toughs" means either.
