[QUOTE="jarance, post: 596187, member: 21"] O2 sensor are sensor to measure the oxygen level after it is exhausted from the engine. based on the reading, it will tell the ECU how well is the combustion. i.e. too rich or too lean. The ECU will then adjust the amount of fuel injection to get the optimum firing. Air flow is measured by the MAF which tell the ECU how much air is flowing into the engine. The MAF also measure the temperature of the cold air as well. [/QUOTE]
