i have a b16 in my crx and it is throwing a code 20, and i looked the code up and it said it was a electronic load detector and i am wondering what a electronic load detector is. and what does it do and where it is located. Also my ecu is a pm6 i had a pr3 in there and it didn't throw any codes but after the car warmed up the engine would die. With the pm6 it never dies but throws a code 20. Any help please.....
