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.
