ENGINE 6 IMV Valve Fuel Temp. sensor Coolant Temp. sensor 6. Air Mass flow sensor (AMF): Amount of air quantity entering the engine is given by this sensor,This input is used by the ECU for corrections of fuel quantity based on amount of air availability and for optimised exhaust gas circulation. Air mass flow sensor 7. Coolant Temperature Sensor: A semiconductor material changes its resistance when exposed to variable temperature source. Resistance decreases as temperature increases. This sensor provides engine operating temperature input to ECU.This sensor is fitted on upper cooling line.Corrections for injection parameters is done by the ECU based on coolant temperature to run the engine with maximum efficiency at all temperatures. 8 Fuel Temperature Sensor: This sensor monitors the temperatuer of the fuel entering the fuel injection pump.This sensor information is used to modify rail pressure control terms at extreme temperatures. 9 Inlet Metering Valve (IMV): This controls fuel flow into HP chambers in order to control rail pressure.This sensor is inbuilt with HP Pump.
