Fakeing the KNOCK sensor

hey guys i think i am in need of a little help , i have a lot of codes and i think that the Ks is making most of them. so i am trying to fake it out with a 470 ohm resistor (1/2 watt 5% tolerance) is that is on the product. i tryed this but i am still getting the code 0304 KS what am i doing wrong. thanks.

0503, 1001 - Front right 02 sensor - Has this been replaced?
0401 - IATS - do you have this connected? Are you using the stock intake?

Until you fix the O2 sensor and IATS sensor codes, don't do anything with the knock sensor.

the 0707 is ok becasue i took out the 02 sensor in the cat . i put on a hight flow cat and did not have a spot for it , do you think that was cuse a ks code, in the hanes book it tells me that the 0707 code is ok and it will not change fuel to air ratio thanks.

The 0707 might be triggering the 0304 - even though the KS has been faked out... you need to find a way to fix the 0707 - just plug in an O2 sensor and clamp it to the exhaust or something

Yes, and no. They make o2 sensor simulators... you might want to look into that.. .there have been several threads recently - scroll back a few pages and you should find some good info.

you said there wasn't a spot for the o2 sensor. How did you hook it back up? Did you stick the old cat back in?

Anyhoo, o2 sensors do trigger the ks code, so do what you have to do to fix the o2 errors first, reset the ecu, then look to see if the ks code comes back.
