扭矩傳感器出現故障會導致汽車出現跑偏嗎

  大家知道當汽車出故障時,我們并不是專業的人員,很難直接判斷哪里出了問題。 究竟是四輪定位異常還是扭矩傳感器出現的故障呢?汽車已然是我們出行的標配交通工具,接下來聽聽扭矩傳感器廠家的工程師怎么說:

  一、故障現象

  例如:一汽-大眾2012款高爾夫轎車,車型為A6,配備CFBA直噴發動機和7DSG變速器。用戶表示車輛行駛時嚴重偏右。

  二、 檢驗與分析

  依照故障的常規特點,維修人員第一感覺出現的偏差是因為四輪定位不準確導致的,于是采用四輪定位儀vag1995k測量了車輪定位的具體參數。

  依照兩個前輪的參考值,汽車按理說應該向左而并不是向右行駛。在調整好正確的車輛定位數據之后,除了檢測四輪定位之外,還有可能的偏差原因如下:

 ?、?胎壓不一致。

 ?、?汽車輪胎磨損不同。

 ?、?轉向角傳感器g85并不是處于歸零狀態。

  維修人員目視檢查輪胎兩側胎面花紋磨損的情況,如是檢測的胎壓屬于正常,這樣就可以排除輪胎故障。當方向盤處于中間位置時,連接診斷儀,自動讀取動力轉向系統的數據。角度為零,校準并初始化轉向角。

  將方向盤向左和向右轉動打死能夠確定電子轉向系統中的黃色故障燈亮起,并且在方向盤返回其原始位置以后,故障立即出現。隨后,維修人員使用診斷儀檢查動力轉向系統。故障代碼為00573。轉向力矩傳感器超過上限,偶爾出現。

  依照故障碼的參數,其故障是由于轉向力矩傳感器信號報錯導致的。扭矩傳感器廠家的工程師指出,由于轉向力矩傳感器向電子轉向控制單元發送錯誤的校正信號,導致車輛在直線行駛時向右行駛,轉向馬達始終具有正確的校正扭矩。

  三、 故障排除

  更換電子助力轉向器后,可以再進行試運轉,從而達到排除故障的目的。
