Ok, before I get too excited here, I have a few questions. I was all ready to order the parts to do a knock sensor relocation due to my bad knock sensor when I decided to pull the jack on the valve cover apart to look at it. It looked good inside with no signs of corrosion. I then put it back, and cleared the codes, then took the truck for a spin. There were no codes immediately, so I drove it for a few blocks, still no codes. I then shut it and restarted it, still no codes. I then drove it about 3 miles with various engine load, everything from bogging it, to full throttle acceleration. Still no codes. I then shut it again for a minute or so. Restarted and drove a few more blocks home. Still no codes!! Did I fix the problem? I will try to explain how this problem started originally, but
I only have a limited pattern from the other day that I posted. I installed the scangaugeII and found the code. I cleared it and checked it the same day still no code. I then parked it thinking all was ok. I started it the next day and surprise! there was the darn code again. I then cleared it, checked it a few blocks later, it was still ok, but then I shut the engine and restarted, and once again the darn code came back!! I then realized through research that the code only comes back if a new event happens after you cycle the ignition. Based on this info do you guys think that the contact in the connector was the problem? (I heard that it was a common issue w/the connectors) If it was a bad sensor would it trigger a code immediately, or is it possible that it is random? If it is random that it doesn't work every now and then, do you think it's worth it to do the relocation, or should I just leave well enough alone and hope it will do it's job if it starts to ping for one reason or another? I'm sorry for all the questions, but I don't want to make a bad decision, I will do what I have to do for the health of the truck, as I want to keep it for a long time. oh, one more question, If I have a bad knock sensor but I am using good fuel and the truck doesn't ping, would it still trigger a code? or does it only trigger a code if it pings (meaning the sensor did not do it's job)? Or are there multiple ways to get the P0325 code?
Thanks again guys.
