How to solve the problem of high fuel consumption of Citroen Elysee in 2002

If you think the vehicle is running out of gas, please ask a professional technician to help you check whether the data flow of each sensor is within the normal range when the engine is working normally! Focus on the data of oxygen sensor, water temperature sensor, throttle position sensor, intake pressure or air flow meter! Judging the general fault direction through the display of data!

Check the throttle, intake pipe, valve and fuel injector for carbon deposition and clean them up!

Check whether the ignition system works normally and whether there is leakage caused by aging of the ignition coil or cylinder pipeline!

Check whether the gasoline pressure is normal and whether the fuel injector leaks!

I hope I can help you, owner. Have a nice trip! If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
