Revotron 1.2T 163 v. Fuel Injectors : Component Details : Injectors are normally closed valve. Injector opens when its electromagnetic coil is energized by the EMS ECU. Component Location : Preliminary Checks : 1. Loose/ Damaged Connections between injector and EMS ECU. 2. Check for back out of pins at both Injector connector and ECU connector. 3. Check for damage of pins at both injector connector and ECU connector. 4. Check the continuity from injector connector pins to the ECU pins. Circuit Schematic Diagram : Connector Information : Con ID Wire ID Color Size Material Option 1 276 L/G 0.75 FLRYB (AD) 2 121A R/Y 1.50 FLRYB (AD) Connector View : Component Specification : The injector is an indirect electrically driven valve (nozzle) that sprays high pressure fuel in an engine combustion chamber. The fuel delivery is a function of the pressure at the nozzle seat. Functional Characteristics:- A:- Pressure Range:- Min operating pressure:- The injector starts to inject at an inlet pressure above 150 bar Max normal operating pressure:- The maximum nominal operating inlet pressure under normal conditions is 1600 bar. Max peak operating pressure:- The injector is
