Primary Oxygen Sensor - Heater
circuit malfunction

What does this mean? Is there something wrong in the wiring of the car? i just did recently install an alarm could maybe one of the wires be hooked to something wrong or something?

 

clear the ecu. if the code comes back, use a multimeter and check continuity of the O2 heater circuit. if that checks out then it's probably the sensor itself.

try searching the archives, there's tons of info.

 

I see.. i tried to search but i couldnt find anything on code 41. thanks.

 

replace the 02 sensor, that will solve your problem

 

Ive never been able to fix an o2 sensor...just bought new ones instead
