So I have a hatch wit a jdm d15b, wasnt passing smog cuz of the chipped ecu, so my friend let me have a p07-L00 to try to pass wit that, at first i was getting 21 and 41 codes, I fixed the vtec pin, it wasnt going in all the way from the harness, now its just shooting 41 which is "h02s heater", I'm thinking the 02 sensor in the header? how do I get rid of that code? or do I just need to get a virgin p28...?

Thanks in advance for any info.

 

replace the o2 sensor, reset ecu, code should go away

 

I dont think this motor has an o2 heater, with the p28 i have it doesnt give me the 41 i think its something to do with the model of the car or the motor type...

 

code 41 is for the "heated o2 sensor". the sensor is "heated" so that on cold start ups the ecu is getting a accurate feed/reading of the air-fuel ratio.

 

But even tho 1 ecu isn't giving me that code, the other is saying the o2 sensor is bad?

 

the "cel codes and how to" thread says that its the primary oxygen sensor HEATER, like there is supposed to be something actually heating the o2 sensor?... It just doesn't make sense that the p28 doesn't give me the code but the p07 does...

 

your chip wasnt looking for an o2 sensor.

 

So if I got a stock p28, it would still shoot the 41 code?

 

I really wanna make sure so I don't waste the money on a p28 and just get the same problem...
