Symptom: a sedan Geely King Kong ( digital throttle ) , the cumulative touring thirty,000 km, appear motor just isn't doing work adequately , iphone news
unstable idle velocity in 830r/min-1500r/min looking phenomenon.
Inspection and investigation : To the use of electronic throttle car, beneath standard conditions the motor idle instability , namely idling tour lexia3
motor vehicles, typically since the digital throttle far too filthy induce , so initial take away the throttle human body , the use of distinctive cleaning agent Pageant valve system and idle pace control valve , put in take a look at yet again , the fault continues to be. Geely automobiles devoted relationship fault detector exam , tune bought to the mixture much too thick fault code appears combination is just too Tuirel S777 diagnostic tool
thick mainly because the ingestion process is often triggered by leaks , since the throttle human body has just been installed , there should really not leak . Then check the canister solenoid valve, solenoid valve as a result of the canister in the ingestion manifold conclude clamp take a look at, the above mentioned indicators disappeared.
Since the initial automobile canister solenoid valve hurt , leading to the air coming into the inlet has become in the solenoid valve, leading to an increase in the intake air , European gas injection then air-fuel ratio , to ensure the fuel injection quantity greater, foremost launch scanner
to far more oil just after in excess of a gas engine speed rise, but as a way to defend the motor , within the method established limitations on idling speed restrict , the vehicle idling speed restrict is 1500 r / min, that is, if the idling engine pace rose to 1500 r / min, Eu lower gas injector spray oil, making sure that the pace right down to the basic pace, as it continues to be leaking, velocity will continue to rise , leading to idle fluctuated .
Troubleshooting: Swap the canister solenoid valve.
