State of the rail pressure control State of the rail pressure control FE63 Rail pressure control state to be noted Rail pressure error Rail pressure error FE20 Error should be less than 100 bar for normal operation Rail pressure feedback Rail pressure sensor feedback FE1 A Rail pressure feedback to be noted Verification condition: Drive the vehicle in city and highway condition. Component Details: Inlet Metering Unit (IMV) is used to control pressure inside the rail. The IMV delivers metered fuel quantity to high pressure pump. High-pressure pump delivers fuel to common rail. The IMV governing is done by ECU based on the demand to maintain the required rail pressure. The Rail Pressure Sensor is used to determine the actual rail pressure. That value is needed for high-pressure control, engine protection and injection control. The sensor is mounted on the rail.
