日产车系在清洗完节气门体后,会出现怠速过高且在1 500 r/min至2 000 r/min之间游车的现象,一般采用日产专用诊断仪(CONSULT-Ⅱ)进行怠速空气量学习之后,游车现象就会消除。但一辆日产奇骏T30轿车在清洗完节气门体后,用CONSULT-Ⅱ进行怠速空气量学习之后,游车现象却无法消除。本人通过探索,要排除日产奇骏T30轿车清洗节气门体后游车的故障,除了用CONSULT-Ⅱ进行怠速空气量学习外,还必须通过人工学习方法才能解决问题。
Nissan car after cleaning the throttle body, there will be idle speed is too high and the phenomenon of traveling between 1,500 r / min to 2 000 r / min, the general use of Nissan special diagnostic equipment (CONSULT-Ⅱ) idle air After learning, the phenomenon of the tour will be eliminated. However, a Nissan Qi Chun T30 sedan after cleaning the throttle body, the amount of idle air with CONSULT-Ⅱ learning, the phenomenon of the car can not be eliminated. I have to explore to exclude Nissan Qi Chun T30 sedan washing throttle body after the car failure, in addition to using CONSULT-Ⅱ idle air volume learning, but also must be through human learning methods to solve the problem.
