故陳評估:此車到店后,著車路(lu)試,熱車機長(chang)期(qi)高怠速,持續(xu)在1400r/min之間不小,原因更為校驗。
接入的診斷儀VIDA讀(du)入錯誤(wu)碼(ma)(ma)碼(ma)(ma),現示節氣閥錯誤(wu)碼(ma)(ma)。展現一種錯誤(wu)碼(ma)(ma)的原(yuan)由有一些幾個也許 :
(1)節(jie)氣門臟污。
(2)節氣門損毀。
(3)節(jie)氣門束(shu)線有(you)問題。
(4)汽車發行為(ECM)毀壞。
先拆下來節氣門檢(jian)修,察覺專門的臟污,刷洗節氣門后(hou)用(yong)(yong)判斷(duan)儀顯(xian)示設備故(gu)障(zhang)(zhang)問(wen)題碼(ma),仍報節氣閥(fa)設備故(gu)障(zhang)(zhang)問(wen)題。第二(er)用(yong)(yong)萬用(yong)(yong)表在測量節氣門邊(bian)的阻值。
#1-#4間阻值1.4Ω主要正潮條件(jian)1.2~3.5Ω)。
#2-#3間阻值1368Ω(規格1000~1500Ω)。
#2-#6在節(jie)氣(qi)門關掉(diao)時差不多為820Ω。在節(jie)氣(qi)門高畫質時差不多為1580Ω。
#2-#5在節氣門關時(shi)差不多(duo)為1480Ω。在節氣門調滿時(shi)差不多(duo)為500Ω。
結杲在精確(que)測量(liang)一直在一般區間內得,是(shi)這樣(yang)就(jiu)是(shi)可以查出以上的(de)的(de)兩(liang)個能夠(gou)主要原因。從(cong)疾病診斷儀中找見節氣(qi)門的(de)三極管圖,對的(de)線路(lu)實施在精確(que)測量(liang):
估(gu)測從節氣門電(dian)源線插頭(tou)到發起機把(ba)控板(ban)塊(ECM)相互間(jian)的路線圖圖是(shi)否是(shi)導通。估(gu)測可(ke)是(shi),六根(gen)線都導通,描(miao)述路線圖圖不存在毛病。
