Wiring diagram of Engine Management System 1MZ-FE Toyota Camry

The engine management system of the Toyota Camry with 1MZ-FE engine includes various components such as:

  1. Engine control module (ECM)
  2. Crankshaft position sensor
  3. Camshaft position sensor
  4. Throttle position sensor
  5. Mass airflow sensor
  6. Oxygen sensor
  7. Fuel injectors
  8. Ignition coils
  9. EGR valve
  10. VVT-i system (Variable Valve Timing with intelligence)
  11. EVAP system (Evaporative Emission Control System)

The ECM receives input signals from these sensors and makes adjustments to the fuel injection, ignition timing, and other engine functions to optimize performance, fuel efficiency, and emissions control. The VVT-i system adjusts the timing of the intake and exhaust valves to improve engine performance and reduce emissions, while the EVAP system prevents fuel vapors from escaping into the atmosphere.
