I have a code 41 primary O2 heater. Is that the O2 sensor that is closest to the head in a 95 civic ex? Also what the best way to get the o2 sensor off the manifold because that thing is on there tight.


thanks

 

wow 2 post about the same thing at the same time.

 

hmmm is the o2 sensor thats on the headers and im havin the same problem as you and to take it off just use a wrench and daz it thats how i did it

 

yes, its the one highest on the manifold/closest to the head

Use the correct size socket/wrench (Ive used heat on dead sensors)

 

19mm wrench?

 

k another thing If i replaced the o2 sensor and the light is still on what else should i check for

 

is it the same code? Did you reset the ecu after changing the sensor?

that is your problem....your primary 02 sensor so if you replace the sensor then I will correct the problem. It isn't like you were gettin a CEL and just guessing the CEL tells you want is wrong, A 7/8ths cresant wrench will get the O2 sensor off and you can just replace it and put the new one back in and your problem will be fixed.

 

alredy did all that replaced the o2 sensor put another 1 in and im still gettin the code

 

and reset it the ecu too

 

up top need help still
