Hello everyone,

I have a 4cyl 2000 accord....I just recently checked my codes and I have a code 41 which is Primary O2s circuit malfunction does anyone know how to fix this....The O2s is 1 month old.

Thanks again in advanced

 

I think code 41 is the preheater for that O2 sensor. Could be a fuse or a broken wire. Check to see if the plug is getting 12v power when you turn on the ignition. Otherwise, the heating element built into the sensor might be blown.
