I have a '95 Accord Lx and the check engine light is on. The Code it is showin is code 41 which says primary O2 sensor/ heater circuit. Is it most likely just my O2 sensor is bad or could it be the whoile heater circuit. If so about how much would that run me?

 

i would just change my sensor period

 

no i would not chnge the o2 sensor unless i know exactly wats wrong.....

1......o2 sensor is unplug

2.....u blow the heater circuit fuse.

3. u change oil, accidently spill oil over.


4...if everthing looks okay, i now change it.....

(never exchange parts.

 

that preluder guy try to screw u man

 

From what i can tell it was not unplugged but i will check the circuit. Thanks for your help.

 

Could it be using aftermarket O2 sensor, i have the same code

 

u blown the fuse, look under driver fuse box.

 

I Checked the fuse and went ahead and replaced it anyway but no go. I figure the sensor is probably bad because my car has 143k on it and i think it is original sensor. Does anyone know about how much a new one will cost?

 

sorry to have to tell you this man..but it's $220, though you can get it for about $160 if you look around.

what is the name of the fuse anyway?

 

160? I just bought a new O2 sensor 2 days ago for 60$. It's just the OEM bosch one at autozone. I was getting the same code as you were and changed it and now it works fine.

 

Sounds like a winner. Thanks

 

I should change my sensor as my car now has 106K on it.....

Not unless it's causing a problem.

 

One more ?...Would that O2 sensor not working cause my car to run really rich? Within the last week i have noticed a not-so-nice black buildup on my exaust and i wondered if that was it?

It can if it's output voltage is biased low.
