About this document
1AZ-FE and 2AZ-FE Engine Control Systems by Juan Espino is a document available to read on EtoBox.
The 1AZ-FE and 2AZ-FE engine control systems have the following features: 1. An EFI system that directly detects intake air volume and uses sequential multiport fuel injection. 2. Ignition timing is determined by the engine ECU based on sensor signals and is corrected for knocking. 3. Systems like VVT-i, ETCS-i, and others that optimize performance under different conditions. 4. The ECU controls components and runs diagnostics/fail-safes based on sensor inputs.
