Elaborate electronic control system fault diagnosis and exclusion, and Honda Accord models with examples of some of its analysis, diagnosis and repair, the last successful troubleshooting process. Honda R D in the new engine has made notable achievements, particularly in the VTEC (Variable Valve Timing and Lift Electronic Control, which means variable valve timing lift control) to identify the engine seems to have become high-performance and high reliability a synonym of automotive power. Since 1983, VTEC technology was invented and first used CBR400 (then known as HYPER VTEC) So far, the technology derived from the DOHC VTEC, SOHC VTEC, SOHC VTEC-E, DOHC VTEC-DI ,3-Stage VTEC, i -VTEC, i-VTEC I and the most advanced Advanced VTEC. The i-VTEC engine technology as the core of the new series in the fuel economy has been greatly improved, for the large displacement engine, also i-VTEC technology to the large displacement 3.5 L V6 with variable cylinder management VCM ( Variable Cylinder Management) engine, in terms of economic VCM engine displacement than the previous V-engine with the increase of 16%. Hondas VTEC engine technology has to improve engine performance at var
