2000年MALIBU油表不准了

huixin

请教各位大侠，2000年MALIBU油表不准，表现为加满油时，油表上升到最高点，但开了100公里之后，指针仍然停留在接近最高点，开到300公里时，指针仍然停留在接近一半的位置。而这之前，开了300公里之后，基本上油箱就见底了。为了验证我的判断，我在开了300公里后去SAFEWAY加油，果然和以前一样加了32升。

想请教一下如果修理的话，大概需要多少人工和零件费？非常感谢你们的帮助！

汽油里的硫化物长期附着在邮箱液面感应器的电阻线圈上，造成信号不准却，所以油表显示也不准确。去GM的dealer买一种燃油清洁剂加到油箱里，能很快解决这个问题。明天我把燃油清洁剂的parts number发上来

非常感谢你的回复！我原来还以为是那个液面传感器坏了呢。先试试你的办法。那种燃油清洁剂在canadian tire能买到吗？

其他的清洁剂不知道是否是专门针对这个问题而开发的，但GM的这一个对清除硫化物沉积相当管用。用了以后有所好转的话，就多用一两次，能慢慢解决问题。如果不见好转的话，多数情况下是液面传感器和线路的问题了，也有极端的案例是纯粹仪表板指针线圈坏了的。

Added Benefits and Uses

The PLUS portion of GM Fuel System Treatment PLUS is the addition of a filmer additive that, when used regularly, can protect fuel system sending units from the corrosive effects of certain sulfur contaminants found in some of today's gasoline.

Sulfur contamination can disrupt electrical continuity of certain fuel sending units and lead to erratic or false fuel gauge readings. With scheduled usage, GM Fuel System Treatment PLUS protects against the effects of harmful sulfurs in gasoline.
