Knock sensor prices.

[p0rk9er]

I just got qouted $360.00 per knock sensor and "secondary trottle position sensor" (cant remember exactly what it was called) priced at $460.00. I have done some research on the knock sensors and found this website with them http://www.autopartswarehouse.....html at half the price I was qouted. My question about the parts on the site is are these knock offs or are the OEM. I am still researching the other sensor if you all have better/more info on these parts I would greatly appreciate it if you posted it.

You ned to read Q45tech's post about factory rejects being channeled into the the third party retail chain.

Get the KS and Harness at http://www.infinitipartsusa.com or http://www.sparkpugs.com

Welcome to our site, and don't be afraid to search first before posting as there is a lot of information posted here.

The labor to change a knock sensor and harness xosts more than the knocksensor..............sure the $360 price wasn't for 2 KS plus the harness?

Plus Labor.

the KS cant be had on sparkplugs.com.... I would recommend getting them off ebay, search for NISSAN KNOCK SENSOR, as long as they are 22060-300PO your in luck.... Pretty much every nissan from 90-now uses the same one....

Except for those who use the factory rejects per Q45tech's post.

I recommend buying from one of the two sources I cited for peace of mind and non-repeated labor. Buying form the low cost seller has its dangers.

not exactly sure what your talking about, however, there are plenty of NIB Nissan/Infiniti knock sensors..... You all know how much I support joe and want to patronize him, but when you can get 2 KS for the price of one from Joe, the choice seems obvious.

As long as they come in some type of oem box and are checked for resistance and banged on the bench to see if resistance changes materially from the impact [medium slamed on bench with your hand measure slam measure slam].

It is a sandwitch in side with the piezo ceramic between 2 metal plates.....over heated changes the materail electrical characteristics.

probably used.

[gabossie]

I believe he sells them for $45, not $20. Yes, I believe they are used.

I'm flexible on the used prices. $40-$45 used and if U buy two used can do for $65.00. Also have new OEM for $90.00 each all prices are shipped prices.

Okay, this is I think the newest Knock Sensor post I can find. I am pulling the P0325. It pulled the code in January, and I was having other work done at the time. My manual transmission PNP sensor was bad and I couldn't reach it so took it in to be replaced and had the fuel injectors cleaned after over 180k miles. The codes were cleared, new transmission sensor has the car running smoother when out of gear, etc.

Anyway the P0325 just came back on. I need to know if there is a way to get to the knock sensor on the 1999 Nissan Maxima VQ30 without removing the intake manifold. If I must remove the intake manifold is it safe to say I will need to replace one or more gaskets? Basically I don't want to start the job without having all the parts needed to get it back together properly. I know I also need the knock sensor harness, or may only need the harness. But with over 180k miles I can't argue about needing to replace anything for the first time.

I also pulled a P0135 this morning. Rather than an O2 sensor it is the front heated O2 sensor heater, right bank. I've replaced a pair of the rear heated O2 sensors over the years and they are easy to find online. I can't find much on the O2 sensor heater. Obviously if this is indeed bad it could be causing the knock that is tripping the P0325.

The Ecu is reporting a KS MALFUNCTION not a KS ACTIVATION, two very different things.

The common way to deal with these codes is to GOOGLE: " Nissan P0325" without the quotes then refine the 6,000+ links down Nissan P0325 Maxima yields 131

Hmmm...a Maxima is not a Q45, so you might want to try a different forum.

We tend to use http://www.infinitipartsusa.com for parts because of price and because of great service. If you don't open a part, you can return it for a refund. They also sell Nissan parts as you will see on their webstite.

Also, call http://www.sparkplugs.com for a quote on the KS (and replace the harness also!) as the website is not necessarily correct with the part numbers.
