The engine runs in "open loop" when first started, before the oxygen sensors come up to operating temperature. It basically means the fuel is being metered with MAP/MAF as the primary input. Once warmed up, fuel is metered by an active feedback loop with the O2 sensor, known as closed-loop operation. Share. cryptololek youtube

"Web15 de mai. de 2009 · Closed loop is basically a condition where the throttle position is very constant (i.e idle and cruise). So all the PCM needs to do is make sure the a/f stays about the same, and all is good. As soon as you open the throttle some, it has to go get IAT and MAP values to determine what to do based on its programming. " - Open loop vs closed loop efi

WebIn contrast, a closed-loopsystem does provide feedback. We’re given a state and asked to produce an action. Once we produce the action, the world is updated and returns to us the next state, and the loop repeats! It should make intuitive sense that we can perform better under a closed-loop system: we get feedback for our actions.
