need to add my 2 cents also on this post.

2002 Solar Yellow, CC, SC, 4x4

After having a heart attack with the dealer quote ($1450) and leaving $95 dollars of my hard earned money I knew there had to be a better way. I started messing around, (trying) to measure resistance, voltage and didn't have any luck getting any real conclusive answers other than I was throwing the P0328 code. It would blow the code, hot, I could baby it until I jumped on it then it would blow. CRAP !!!!

So after looking at the engine for a while, I reviewed the troubleshooting from the factory CD I purchased on EBAY. One step says to check the ground. The ground is on the SC and it looked fine. Well....for giggles I got a 10mm socket, unscrewed the bolt, moved the position of the wires to a slightly different angle and re-tighened. HOLY COW it worked *** only intermittently ***. I drove the truck around the block, watched the SES light pop for a fraction of a second (it reset the code) *** Hey idiot, that was the washer fluid light that flashed, not the SES light **** and walla, I have a truck that will burn rubber like it should have for the past 6 years I have owned it. I was surprised to find the code will blow without showing the SES and its probably been showing that same code ever since I bought the darn thing.

I must say, I got ***SEMI*** lucky with this one, but its a quick check that should be performed before you got to the trouble of a relocation or a resistor fix, maybe you will get luck too.

I have compiled a word document with the best information that I copied from the various places on the internet and will be willing to email it to anyone interested. I did not post here because I cannot quote all the sources the information came from and don't want to disrespect any moderators.

I have a brand new love for my Nissan, and this sensor problem is common in the N/A version too, but does not require a fix since my research shows it does not affect N/A performance in a noticeable fashion. Since I have saved myself a bunch of money, i'm getting a gauge pod, boost gauge, likely oil pressure for the pod, and possibly slotted/drilled rotors, and a pulley mod....Thanks for the great info on this board....Eric S.

**** UPDATE ****
The code seems NOT to blow when the truck is cold I don't get reduced performance. It seems once I put the A/C on it blows the code and goes into failsafe mode. If the truck is run, then parked and started, it goes into failsafe mode.
It has also been pointed out, my assumption of not affecting the performace of the N/A is not correct, don't know since mine is the S/C.
When the code does not blow it runs like an animal. I will continue to try to isolate the problem, double check the timing and probably go over the spark plug wires again, thanks to a later post....Cheers, ESS.
