Toyota 1AZ-FSE Engine Service & Repair Manual

To replace the 3S-FSE engine, more advanced 1AZ-FSE, 1JZ-FSE motors were developed. Many shortcomings were eliminated in them. The developers have changed the cylinder blocks. We redesigned the high pressure fuel pump, changed the injectors, the throttle valve block, the EGR system, and the additional flaps control circuit. Reworked the injection control algorithm.

 

And we changed the diagnosed (scanned) date of the displayed parameters for more accurate diagnostics of motors using scanners.

It should be noted that the 1JZ-FSE engine is taught to work without high pressure (unlike the 3S-FSE engine), while the car is capable of moving, with limited power and rpm.

The transition of the engine to lean mode is carried out under certain conditions. However, if any serious and not very serious interference (malfunction) occurs, the transition to depletion mode will not occur. A dirty damper, problems in sparking, fuel supply, gas distribution do not allow making the transition. At the same time, the control unit lowers the pressure to 60 kg.

The 2.0-liter Toyota 1AZ-FSE engine was produced by the Japanese concern from 2000 to 2009 and was installed on many of the company's popular models, for example:

  • Toyota Avensis
  • Toyota Avensis Verso
  • Toyota Noah/Voxy
  • Toyota RAV4

  • Toyota Isis
  • Toyota Ipsum
