I have a code for my upstream o2 sensor that went bad and after i replaced (because it was effed) i still have the code for the heater circuit malfunction. I bought a denso o2 sensor. does anyone know of a good diy on this?

 

Year, make, model, exact code?

 

1999 acura integra gsr p0135

 

Newer vehicles have fuses for the o2 heater circuits so i would look in your owners manual.
