Explanation of the most important sensors that, when they fail, cause increased fuel consumption and increased gasoline consumption. What is the relationship between the air sensors / absolute pressure sensor and the air sensor / MAP / MAF and the increase in fuel consumption? What is the relationship between the oxygen sensor / O2 and the increase in fuel consumption and gasoline consumption? What is the relationship between the engine temperature sensor / coolant temperature sensor / ECT Sensor and the increase in fuel consumption?
