p0141 Powertrain Bank 1 Sensor 2

上个星期换了 234-9014 (Upstream) 没问题，今天换了 Oxygen Sensor 234-4122 (Downstream) 就出现p0141 Powertrain Bank 1 Sensor 2， 我原来的Sensor全部都没出现过error code的, 因为用了这么多年了就想换个新的就出现问题了。请问大家知那里坏了呢?谢谢

amazon也有个买家也出现p0141 error.

我的car 是 2002 Accord LX F23A4 Engine

 

为什么没code要换呢?因为MPG少, 

还有

MALFUNCTION INDICATOR LAMP stay on 20 sec and flash 5 time and gone

O2 sensor and Catalyst Monitor ,EGR System Incomplete

要开10-20分钟就会自动变 Green了

如果停车，turn off.  再开又变红了， 又要开10-20分钟就会自动变 Green了

• 你之前换up stream sensor时断电池或clear code了吧。之后需要足够的drive cycles 才完成ecm -hellotom- ♂ (694 bytes) () 09/29/2019 postreply 06:35:53
