Code 41
 

this morning im driving home and my speedo is dead. everything else works. and speed starts goin crazy ... acting like an afr guage basically.
I got a CEL and its code 41.
i have p28chipped b16a2 obd 2 to obd 1.
on ht it said primary oxygen sensor heater
*ALSO my volt meter goes from 13-14volts ..keeps going back and forth and the CEL light also goes dim than brighter again, if its an emissions problem why is the power acting weird.

could be an electrical problem as well causing the code, check your grounds really well before you go doing anything else

need help. just spent 5bills on alternator and still same problem

why in the hell did an alt cost 500bucks?????

honda.

dont ask why. the part was honda n i had it at my mech.

jesus you got ripped......welll like bruno said check all grounds and check all harness plugs by jiggling them to see if that does anything

not really. I paid wat a alternator costs from dealer plus 100$ to install. and by the way it wasnt the alternator so he didnt charge me. I found the problem. thanks bruno
