Fuel and air metering

How much air and fuel the engine is receiving, and the sensors that measure it - mass airflow, manifold pressure, intake air temperature, oxygen sensors and fuel trim.

No open-source descriptions exist for this system, so its codes are read from their structure.

Manufacturer-specific. Check a source specific to your make and model year. The subsystem digit is still a reliable hint.
