Emissions questions. O2 and knock sensor questions

[tmracing83]

First off how would I go about fixing my knock sensor? Clean it? Change it I'm guessing... Any normal problems with the knock sensor that cause it to throw a cel?


Also. I need to change out my front o2 sensor, but I had a code which came back to be "o2 heater". Can anyone explain to me about the o2 heater? And how to go about fixing that?



Try to figure out 1 what parts I need to buy to replace and also how to go about fixing it...


O2 is simple.. I've never heard of the o2 heater though... Don't forget about the knock sensor too...



Thankyou.
