Fuel Temperature Sensor for the EFI V8 petrol engine, part of the electronic fuel injection management system. The sensor measures the temperature of the fuel and reports it to the engine ECU. The ECU uses this reading to correct the injected fuel quantity for changes in fuel density and to manage hot-fuel conditions, helping maintain accurate fuelling and consistent starting and running. It operates as a temperature-sensitive resistor whose resistance changes with fuel temperature. Show more
