Guys, I need help: I got 0901 Front Right Htd 02 sensor heater and 0304 Knock Sensor codes. I doubt that they both died at the same time. Is there an easy way I can test and replace them myself without going to my "friendly" mechanic? By easy I mean december in NYC is not the warmest month in a year. I know that if I'm gonna go to the mechanic his gonna rip me off, better off doing it myself. Can you believe that this ***** charged me $60 for a door-switch air bag light reset back in a day when I was an amateur at this. After seeing this I said "WTF, $60 for this??". He said "The light is off, isn't it?". Nevermind that it came back on a week later. Sorry for the long post.

 

By the way it's a 99 SE.

 

change the 02 sensor.. reset the codes.. and kiss your mom and tell her you love her

 

But what about KS? Thanks for the reply. How much is O2 sensor anyway?

 

The knock sensor code is a "dummy code" when the O2 sensor code is tripped. Don't worry about the knock sensor yet. First, replace the O2 sensor.

Get a BOSCH (OEM) O2 sensor from any reputable autoparts establishment. I purhased mine from www.foreignpartsplace.com for $55.00 shipped. Good luck.

 

Thanks guys for the replies.

 

Guy, does anyone know another good place on the web to get o2 sensor? That site is down.

 

Also, does anyone know the part number for the right front o2 sencor? Thanks.

 

I would call all your local dealerships around, talk to em on the phone to get prices and ask "whats the lowest you think you could get that to me buddy". i always save about 25% on anything making friends over the phone real quick..
