How does Citroen clean the throttle?

Regarding your question, the increase in fuel consumption has something to do with the carbon deposition on the accelerator and the electronic control system. First, check the carbon deposit on the throttle body. If there is carbon deposit, please clean it up before observation. Secondly, it is very important to check whether the signals of oxygen sensor, water temperature sensor and intake pressure sensor are normal. The engine computer mainly calculates the fuel injection quantity according to the signals of these sensors. Then check the working conditions of the ignition coil and spark plug, and use the diagnostic computer to see if the ignition time is normal. Regarding the cleaning of carbon deposits, it is recommended that you clean the throttle body every 15000 km and the air inlet and injector every 30000 km. It takes about 400 yuan to do these two cleanings in a 4s shop. I hope my answer is helpful to you.
