Does anyone know what the hell that code is..?? I just replaced my thermostat and now i have code 41..???

 

The O2 heater is exactly what it sounds like. It helps get the O2 sensor to its operating temperature of 600 degrees Fahrenheit and also helps to keep it there.

 

dude i got bad *** luck today huh... i just replaced my thermostat would that have anything to do w/ it..??

 

As far as I can remember it shouldn't.

 

is there a fuse for it...?? im reading through the archives and seen that someone said they checked the fuse for it...??? or a way i could reset the ecu or something...

 

No, it has nothing to do with it. If you reset the ECU and turn the ignition on (engine off), does the CEL immediately turn on? If yes, grab a meter and measure the heater resistance of the O2 sensor. Should be 15-40 ohms. If its not (which is sounds like it isn't), then you'll need to replace the sensor as whole.

 

I reset the ECU, put ignition in ON position... nothing happened... idled for a few minutes... still nothing... drove car around neighborhood, about halfway down the block CEL popped on.. got home checked code.... 41....

 

So get a meter and measure it.

 

make sure the o2 sensor is plugged in. then you will porbably need to replace the o2 sensor

 

i reset ecu and made sure everything was plugged in right, and it still comes on... what sorta meter should i use to check it...?? and what exactly am i checking on the sensor...?? dont mean to sound like an idiot but i've never had 02 sensor problems before...

 

Autozone up the street from me has a Bosch Universal O2 Sensor that I found on their website that is supposed to be the one that matches my car and its only 50 some bucks.. is that the same thing as the OEM Honda one thats like 200 ...??? if so y the huge price diff....

 

no, it's not as good, but it will work

 

without throwing a code..??? does it have a heater inside of it like mine does.. cuz from what i understand.. theres a code for bad 02 sensor an theres a code for bad 02 sensor heater....

 

i'd measure the ohms on the heater control circuit and the oxygen sensor input circuit from the o2 to the pcm, measure + for the heater sensor. i don't know if it has power on accsessory or run. if, you have good ohms and + on the heater change the o2

 

I've had this code since I swapped a z6 motor in my car.
I have yet to get a new o2 sensor, but when I do i will update

get a new o2 sensor

 

no offense.. but that was like reading german mixed with chinese to me... what sort of meter do i need...?? and what wires are the ones ur talking about... mine are colored..

 

a multi meter

 

i can get one of those at autozone right...?? is it sorta like a circuit tester to check an see if something gets power..?? but it has a digital readout...

 

how long have u had the code for...?? has ur car rode diff..???

 

i haven't had the code before, but i know what it is and how it works.
yes, it's a digital multi meter

 

i can e-mail a schematic to you

 

I have the same problem right now as well. my CEL has been on for a while, maybe a month or two. the only difference i can tell in the car, is that it kinda stutters when i switch on the headlights or when you turn very slowly. look into a denso o2 sensor. they are supposed to be better than the bosch. you can get a universal one and wire it yourself or spend some extra cash to get the one that just plugs right into your wiring harness.

 

Yeah if you had the schematic that'd be tight.. cormega73@aol.com thats my email

 

I'm sure Advanced Auto has a meter. Yes - a circuit checker - something that can measure resistance.

Unplug the O2 sensor from the main engine harness. Locate the two black wires and then measure the resistance between them. There are two pins and two probes from the meter. It doens't matter how you hook them up to do this measurement.
