What is an EFI system?

The Electronic Fuel Injection (EFI) system has been built to fuel your vehicle's engine efficiently, ensuring a smooth running with maximum performance and minimal fuel usage. If any malfunction occurs, it will be evident through increased fuel consumption, as well as other irregularities.

Your Electronic Fuel Injection (EFI) system ensures that your vehicle runs efficiently by supplying the engine with fuel quickly. Symptoms of an EFI malfunction include an odour of fuel in the cabin, jerky idling, difficulty starting and persistent stalling.

If you suspect you have a problem, bring your vehicle in for a no obligation inspection before it gets any worse. We are located in Smithfield, Cairns and also serve customers from the surrounding areas.

Our various EFI services include items such as;

  • Diagnostics, testing and inspection
  • Repairs and replacements
  • Cleaning your Throttle valve, fuel filter and fuel injector
  • Checking sensors
  • Checking engine control unit (ECU)

For further insight into issues with EFI and our approach to troubleshooting and resolving them, here is additional information.

  • At Smithfield Car Diagnostics we use special computer Diagnostic equipment to test your car's ECU (electronic control unit). The ECU is basically a central computer which controls (amongst other things) the fuel injection process by taking information from the many sensors spread throughout the vehicle and making “decisions” based on pre-programmed inputs. The ECU can ‘self-diagnose' faults and send out a special fault code which our diagnostic scan equipment is able to extract and interpret.
  • Quite often, the ECU is being given ‘wrong' information by faulty sensors or other environmental factors and this is when we have to call upon our expert knowledge and advanced diagnostic training to correctly identify the problem.
  • Electronic probe testing and visual inspections can be made of your car's sensors, throttle valve, fuel filter, fuel pump and fuel injectors to make sure they are working correctly
  • Any leaks must be located and fixed without delay - Air leaks will seriously affect performance and fuel economy and can cause severe damage to engine components and quite obviously we don't want fuel leaking out anywhere!
  • Over time, Fuel lines, filters and valves can become clogged with contaminants or tank sediments so they'll need to be cleaned or replaced. Where necessary components can be unclogged using special flushing compounds.
  • If any sensors or the lines connecting them to the ECU are damaged they'll need to be fixed or replaced. While your car technically might be able to function without some of these sensors, they all keep track of information that is vital to the efficiency, performance and safety of your vehicle so your ECU will usually not let you run the vehicle until they are fixed and it will often send the vehicle into a state of basic operation known as ‘limp mode'
