Re: closed loop/open loop, explanations ?
To clarify the above, closed loop occurs when all sensors are working and feeding data to the computer. The engine will not enter closed loop operation until the EGO sensor (that's Oxygen Sensor) is warmed up - generally between 1-2 minutes of operation. In open loop, the computer discards data from certain sensors and runs a program with pre-determined levels for various conditions - generally this is not optimal and is often referred to as "limp mode". If your SES light is on, you're generally in open loop operation.
