CSR tech guys,
I am new to fuel injected engines. Been with carbs until now. I am asking for help identifying the various sensors plugging into the throttle body. I really need to know what they are and what they do and if they should be changed as routine maintenance. Asking a lot, I understand. I can easily look at a diagram, but that would not bring the wisdom with it!
Any educators out there?
The two pictures attached are from a 2001 Mercruiser 4.3L EFI.
At the 4o’clock position, I know the black sensor is the Idle Air Sensor. Don’t know much about it, but the name.
This picture is of the flame arrestor.
