车是VW Passat 2004 1.8T. 开了7年多了。从没Flush过 collant。
上周五，车刚打着MIL就灯亮了。自己拿OBD reader查，code = P0117 (有两个，后一
个是Pending)。试着erase了code，还把电池断开又重新接上，当时Code似乎清了，但
今天车刚打着灯又亮了。
查出来的P0117 = Engine Coolant Temperature (ECT) Circuit Low Input
Potential causes of the P0117 code include:
* Bad ECT sensor
* Short to ground on ECT signal circuit
* Faulty or damaged connectors
* Wiring harness damaged
* Loose terminals at ECT or PCM
* POSSIBLY an overheated engine
* Bad PCM
因为code和灯是车一打着就亮了，所以我觉得不大可能真是Engine过热。而且这两天开车还留意了水温表，基本上就在中间。
哪位兄弟遇到过这个问题？估计是要换ECT sensor还是要flush coolant?
另外月初电池死了，从附近一家专卖德国车部件的店里买了一块InterState电池。不知
道跟换电池有没有关系？
多谢！

Yes. The temp is in the middle a couple of minutes after start.
