Last night driving home from work, I thought the car felt weird, as though no matter how much gas I was giving it, it didn't have the spunk it did yesterday or the previous week. Well, today as the temperatures went up, I decided to head over to my friends house to help work on his tailamp project that he has going. Along they way, I felt that the car was sluggish, but I thought maybe that was due to the temperature and I was just crazy. Then down the drive more, it seems as though there was inconsistant performance. I got to my friends house, I decided to lurk around the stickies above to find out how to read ECU codes. Well, as it turns out, I have 3 long blinks and 4 short links.....

0304 knock sensor code

I'm going to call around for prices on Monday but in the mean time, I've read up on using a standard 470K lead resistor to fool the KS into thinking there is the correct voltage. I went to autoparts stores but they don't seem to carry them. What type of stores should I be looking at for one

It seems to be inconsistant, which would mean mine is about to die. I cleaned out the connector along with the subconnector. Dirt popped right of of them as soon as they released. I drove back home and the acceleration was back, it didn't seem like the ECU was pulling timing, or going into a default safe mode. I decided to disconnect the battery (negative) to clear the code for now and see if it returns back in a couple days of driving. I figured it I still get the 0304 code, Im just going to use the resistor as a temporary fix until I can get a new KS.

 

I have a new KS for sale, PM me if interested.

 

As far as I know, disconnecting the battery will not clear the code(s). You have to turn the screw on the ECU to reset it. By the way, I'm pretty sure there was a knock sensor GD or something. Maybe it was in the 4th gen "for sale" section. I'd check it out. Good luck.

 

you're correct, the stickies above says to turn the screw clockwise,counterclock wise,clockwise,counterclock wise to clear the ECU
