2006 Impala 读码0641
车型: 2006 Impala, LT 3.5, 192000公里. 现象: 启动后, 或开出几公里, 踩油门不加速, alarm响, 出“Engine Power Reduced”和“Traction Control Service”的错误提示. 其它刹车和转向均正常, 停车后熄火, 再启动正常. 其它异常: 加速时有顿错感, 有时一蹿一蹿的. 读码: 0641, 解释如下: The control module has 2 internal 5-volt reference buses called "5-volt reference 1" and"5-volt reference 2". Each reference bus provided 5-volt reference circuit for more than one sensor. Therefore, a fault condition on one 5-volt reference circuit will affect the other 5-volt reference circuits connected to the reference bus. The control module monitors the voltage on the 5-volt reference buses. 去车行检查, 老板以前没见过这样的情况, 基本上也是在网上找, 还有就是凭以前的经验试. 各位大侠和同党, 哪位有过类似经验, 请给说说. 谢谢. |

替你放狗搜了一下 http://www.fixya.com/cars/t13038191-...41_code_anyone Q: 2006 chevy impala p0641 code . Has anyone found 2006 chevy impala p0641 code . Has anyone found the exact problem? The message center in the car says reduced engine power,service traction control,low oil pressure,it has even turned the car off and said( starting disabled service throttle) . I have already cleaned throttle body and problem still exists A: You will have to replace the throttle body. The same thing happened to mine. Once you've replaced the throttle body, there is also a sensor in the gas pedal assembly that may have to be replaced. The mechanics told me they usually replace them both at the same time but I only replaced the throttle body & it took care of the problem |

Update一下. 决定换throttle body后就开始找, 在本地新的要300~400, 即使是auto wrecker的也要至少$100一个, RockAuto新的$135, 加运费和税$181, 没说的, 下单. 星期五收到, 到车行装上, 前后半个小时, 完了老板问能不能给50, 我当时就乐了, 50就50, 还能不能. 以前出了状况来检查或读码, 从来不收钱, 人家的时间也是钱呐. 换了新的throttle body后, 开起来顺畅多了, 顿错感完全消失, 油门好象也比以前灵敏和轻松. 相信就是这个问题, 230能搞定我已经很满意了. 我不是DIYer, 换油都去车行, 但喜欢瞎看跟自己车有关的东西, 包括西人的论坛, 基本上心里就有数了, 这样一来就能尽可能少或避免花冤枉钱. |

上次换Timing Belt,我对师傅说换的时候,加点小钱,顺便把里面的油封帮我换掉(同时提醒师傅位置对准点,别换不好,漏油你得返工),修车师傅说你好像挺懂的,我其实都是上网看来的,至今我也不知道是那个油封,位置在哪里。 后来去拿车,那个师傅说第一次位置没对准,试车发现漏油,只好拆了重新做。 |
