B******1 发帖数: 9094 | 3 So what is causing my P0420 code?
There are a number of things that could be causing this p0420 catalyst
efficiency code. The most common thing is the catalytic converter itself is
no longer functioning properly. The other likely thing is the rear O2 (
oxygen) sensor is no longer working properly. Other things could include
exhaust leaks, damaged exhaust pipes, damaged O2 sensor wiring/connectors,
plugged catalytic converter, etc.
OK, so I want to diagnose things, what do I do next?

但是catalytic converter 前面的O2 sensor,必须用个 O2 sensor wrench, 因为一般
的扳子根本够不着。而且就算有O2 sensor wrench,也不容易拧,你力气小些,扳子根
本不转啊。我是用锤子砸扳子,然后带动O2 sensor wrench,最后sensor 就松点了。
一个多钟头才搞下来。也是累个半死,当然没喷什么PB啊啥的。所以车铺子要60刀的

问题出现经过:
前天晚上,加油门时偶尔听到前盖方向有轻微的叮当响,像茶杯盖擦碰茶杯的声音,很
脆,没怎么在意。 昨天在路上,加油门时,突然听到引擎传来巨大的轰轰轰的声音(
声音是突然变成这种很大的轰轰声,不是之前听到的引擎噪音),我还以为是旁边开来
哈雷了。个人怀疑是muffler 出问题了,不过声音不像是从后面来的,所以也可能是前
面的catalytic converter。现在车正常运行,只是加油门声音很大,感觉油门没力,
加油门或路上颠簸时偶尔还有叮当响。不知道是否只是muffler的问题,如果是
catalytic conveter,是否有必要换,请高手指教。谢了。
车是从dealer买来的旧车,有2年的power train warranty, 买车的时候dealer比较无

s********k 发帖数: 46 | 12 刚买的二手车check engine light就亮了(mechanical check时没大问题),车行查完code说是catalytic converter坏了,换新的加labor估计要700+。
组里老外建议联系ford custom service因为ford有transferable emission warranty for 8years or 80000miles,打电话过去ford确实说如果是emission system的问题并且warranty valid的话可以免费修,不过如果不是emission的问题或者因为过去车主过错void warranty的话不给修还要收80-150的diagnosis fee。
上一任车主说过去有过类似的情况是因为fuel cap没盖紧过几天就会好,我也倾向于相信他,不过撂了三四天了灯还没灭心里不踏实。
请问高手有没有价值去ford dealer那看看呢?谢谢了!
另外在版上考古了一番,发现XX管子破了,fuel cap不紧,O2sensor,catalytic
converter等啥问题都有可能,请问这些问题都会给出同样的code吗? |

网上和autozone有更便宜的part。感觉labor 是1-2hr.

我问他们反正凑活2-3月没问题。

get second opinion from a qualified and honest mechanic
if that is the reason,

3.find a cheap garage to install it for you

g*********r 发帖数: 9366 | 20 bad O2 sensor could cause immediate damage to the catalytic converter, which
is very expensive, especially considering the LZ 's car 's mileage: his car

also bad sensor could cause incorrect fuel/air ratio which will result in lose of
