Code 23 & Code 41???????
Could someone please tell me what code 41 is (Primary Oxygen Sensor) - Heater circuit malfunction. Isn't that the o2 sensor? I just replaced it with a new one and it still throws that code. So could it be the wiring, how would I troubleshoot that?
Also the 23 is the knock sensor, any one have one for sale
Thanks
