Actually I've used all three situations. I have the boost gauge and see when the sensor trips. 2 lbs of boost. I borrowed a scan gauge and when the sensor trips and see theres no boost I then look at the scan gauge. yep, a p0328 shows up. You can clear it then but it won't reset untill the engine is stopped and restarted. Also, like I said. take off with a tripped sensor with the a/c on. The truck struggles.

The sensor is extremely tempermental. Got all the way into work this morning and the sensor didnt trip.

Same here, mine doesn't act up all the time. It's like it's messing with me.

After talking to several mechanics that have worked on Nissans of all types for years, I was told that the knock sensor gets more and more sensitive as it gets older. And it seems the ones Nissan uses are the worst of the worst.

Great, thank God I got a 7 year/75,000 mile extension. Unless ofcourse the pricks give me the runaround and tell me that it's not the knock sensor or that it's my fault due to modifications again. :rolleyes:

Yeah mine goes in on the 25th to get the sensor changed...after going there 3 times and tellin them the same symptoms mentioned in frontiers post. I finally told them to change it!Period! It's not like they won't get paid for it so whats the big friggen deal. And by the way, it's been running fine but I know it's still there!! Damn government mandates!!!

Are you refering to this [URL=http://www.amazon.com/ScanGauge-Compact-Multifunction-Computer-Customizable/dp/B000AAMY86/ref=pd_bbs_1/105-7441547-5958868?ie=UTF8&s=automotive&qid=1187312887&sr=8-1]LINK[/URL ] or a code reader?

Bige
Thats the one. Just remember, you can reset the code on the fly with the scan gauge, but since the KS is a one reset sensor, it requires the engine be turned off and on to totally reset.

Oh, I thought you were refering to a code reader. I don't need a $150 gizmo to tell me the knock sensor is crap but the dealer sure as hell does. You got me all excited that I'd have some hard/idiot proof evience to show the dealer.

Well shit, I pay off the X and shit starts to happen. My SES light lit up went to AutoZone and Not only did O2 sensors come up bad but so did the PITA KS. I dont guess any one replaced it on there own, and if so is it worth the headache or should I pay some monkey (no offense Allen/mechanics ) to do it?

I heard that if you have a body lift you can reach the wires that go to the knock sensor so that you can relocate the knock sensor to an area where you can change it without paying $1000. F*cking Nissan! I don't understand how some people on here can act like having to replace your knock sensor is regular maintenance. :rolleyes:

Yea man, from what Im seeing its a FAAAAR cry from changing ones oil,flushing rad., brake job and what not. It ranks up there with timing belt change. BTW no body lift here, DAAAAAMN IT.

Sounds liek an excuse to get one! I'm thinking about doing it in the spring.

You have got to be kidding me. No other input/advice on this issue.

There's a lot of posts about this. From what I've heard, it's in the center of the engine and costs about $1000 to have done.

Yea, BigE, Ive read/searched the issue. Has anybody done the fix and if so how involved is it. One post said somthing to the effect that the SC needed to be removed, if so why. As far as the location it does not make sense to me to remove the SC.

I've never done it, I don't intend on trying. I'd rather push it off a cliff than try to do that!
Good luck!

Yea its a real PITA. I guess Ill try and bypass it, are there any ill side effects to that that you know/heard of?

I am having this same problem and have been fighting with Nissan. Their Conumer Affairs Dept. is the worst. I will never buy another Nissan product again after all of this. Woodfield Nissan flat out lied to me also. Went to Autozone, they ran a scan, P0328 of course, took it to Woodfield Nissan in Schaumburg IL and they ran a test, "claimed" there was no code and I found a print out under my hood with P0328 from the dealership 2 days later!! Bastards flat out lied to me and charged me $107.

Might try to fix this myself this weekend. Let me know what you guys find out.

Blower and manifold must be removed to access the KS. You'll need a new set of gaskets for the blower and manifold to put it all back together.

Mine now has the problem of the blower itself is making bad bearing noise. Went to a PSE blower website and found a replacement for $650.00. I called and talked to a rep and they said if i got 100,000 miles out of an eaton blower then I did good. he also asked how often I changed the fluid. I said Nissan didnt have a change interval for it. That lit him up. He said it should be changed every 30,000 miles.
So lets see:
KS replacement $750.00-$1000.00
New blower $650.00

This really sucks!

What?!? Wow, thats ridiculous! I'm surprised no one has come in here to defend Nissan yet. :rolleyes: I jus mailed my last payment out and I have 45,000 miles so I'm not about to trade my X in but it is annoying.

I LOVE my truck. Don't get me wrong, but if you have issues, there should be a good customer service team to take care of you. Nissan is a major co. and they SUCK at customer service.

I also talked to Woodfield Nissan last year about changing the oil in the supercharger and was told I don't need to because it gets lubricated buy a feed from the engine oil???

How do you changed the oil in these Eaton's?

The blower does not get lubed by engine oil. The supercharger is an independent system. There is a small plug on the front of the blower that you would remove, drain what you could and refill. There is a special blower oil/lube. I don't think Nissan looked at the supercharged engine as a long time use engine. How could they if theres no mention of a blower oil change interval.

Just spoke with another dealer and he also said that the supercharger gets lubed from the engine oil. Are you guuys 100% sure it is fully independent and needs oil? That is what my first thought was. I also put in a call to Nissan Corp. again. Last time it took 10 days for a call back.

Let's see how long it takes this time!

I'm going by what PSE told me. I've looked at my blower and cant find an oil line to it.

Im curious what sort of life expectancy Nissan expected out of the SC engine?
