i got a code of P0141 "O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)" couple of days ago and erased the code then today it came back. i did some research on this code that it might be the #15 fuse (7.5) or it could the the connection on the engine bay (from the sensor) "The engine wire harness is rubbing on the intake
manifold bracket." http://www.tegger.com/hondafaq/tsb/civic/x99-029e.pdf
if these 2 are ok.. i just have to replace the 02 sensor (secondary)?
btw, is front, primary? and rear is secondary?
Honda Part #'s
36531-P2E-A01 = FRONT (#8)
36532-P2E-A01 = REAR (#9)
NTK24542 = UPSTREAM
NTK24633 = DOWNSTREAM
234-4099 = UPSTREAM
234-4065 = DOWNSTREAM
ok, i checked fuse #15 (7.5) and its not blown. i didnt check the wiring on the engine bay because my fuse is ok. yesterday CEL came back again (3rd time) coz i keep on erasing it. so i was thinking maybe its really the sensor.. but which one?
