check engine light diagnosis and fix

toyota 4runner 2001, 228k miles, check engine light on, also vsc, trac light on.

diagnoised with p1135, oxygen sensor, upstream.  

 

bought parts via amazon, oem, and install by removing two nuts, and removing the eletrical connector.  

 

 

happily gone after wiping out code, and drove 50 miles (a day commute).

• 挺順的。接線那頭因為空間小使不上勁花了十幾分鍾。 -leslieking- ♂ (0 bytes) () 10/13/2015 postreply 20:56:42
