98 pathfinder knock sensor
Hi folks, a newbie here. I'm not sure if my knock sensor is bad, so, here's my
problem.when i drive my 98 pathy up hills lately it makes a pinging sound, i've tried higher octane gas= no help. there are no codes lighting up and the motor still runs smooth, but i can definitely hear the pinging up hills.I read that driving continually might damage the motor. so, does anyone know of what might be causing this pinging sound other than the 'possibility' of a bad ks ?. one thing i recently did was i cleaned my throttle body with o2-safe spray. but, i didn't know till later that i wasn't supposed to hold the plate open with an object , but i used a small piece of wood to keep throttle plate open while i spray-cleaned it. no codes, runs fine, but', now it takes a few extra minutes to idle down to normal 650-750 rpm. could this have any affect on the pinging? or not? i tried disconnecting the battery for a while but it still won't re-learn the idle. could this be causing the ecm to change the timing and cause the pinging?..sorry such a long post...thanks. |

Locating the correct wire color on existing harness
Anyone know what color of wire I am looking for on the existing harness? Before I splice the relocated new wire to the existing for a knock sensor relocation, I want to be sure I do not cut the fuel wires. 98 Nissan Pathfinder.

IM doing a little reasearch for one of my mechanics at work. he has a 00 nissan quest with the 3.3 I was hoping this would work for that vehicle but his manifold is composite and the harnes locations are diffrent. would it still be the same basic principal?

Metal rattling sound during accelerating
Anyone ever have a metal rattling sound during acclerating only? I have a 98 Nissan Pathfinder, 154,695 miles, v6, 3.3L engine. I did the knock sensor relocation using the video youtube.com/watch?v=2t1l68s8MmM, replaced the mass air flow sensor, the egr valve, and my battery. I need to drive another 100 miles an order to reset the systems for an emissons test retry. Any advice on the metal rattle during acclerating would greatly be appreciated. I already replaced the intermidiate exhaust pipe, muffler and resonator assembly.
thanks |

I just had this happen to my 04 Frontier. I did relocate the knock sensor (stock 04 Frontier knock sensor new ebay $7 shipped) but didn't have to cut/splice any wiring. I was able to remove a small mounted heater hose line in the back of the intake manifold allowing for just enough room to unplug the stock harness and reroute it to the new location. I left the old sensor right where it was because i could not get to it with tools. It was very tight and took about 1hr total but worth not cuting the harness for me. It was 2 10mm bolts and 1 hose clamp, then fold the hose and flange still attached to the heater side back out of your way to reach behind. You will need to add some high temp gasket maker to seal the flange back to manifold, but thats super easy. Its running as good as new and no further problems.

Don't hesitate to do this. I was reluctant but it's a 15 min job & it works. Bought both the sensor & harness on eBay. They range from $10 to$100 but are all the same.
You only need to splice into one side of the sensor with the wire. The copper shield is a ground & the sensor is grounded so it becomes a 1 wire conversion. Just be sure to tap into the right wire ( the one with resistance to it) I actually cut the other one off as it served no purpose. Because I had disconnected the battery to perform this, when I fired it up the codes were cleared. 1 month & counting. Save yourself the big bucks - this is a true DIY. |

Verify ??????????
I can see that this relocate knock sensor can work with a new sensor and wiring..on a 3.3 L ENG.. So as too turn off code... BUT HAS anyone tested to see if knock sensor can detect a real spark knoock with it located on upper intake plenum..... Seems it wouldnt be able to begine too detect a real spark knock.... with it on upper alum intake.. Seems that it would have too be some how located to the lower intake in order too maybe detect a real spark knock..... Just my thought....

97 pathy
I have code PO325 KS on my 97 pathfinder. Has anyone done the relocation on a 97 pathy??

In a late response to #44 & others ... I had codes P0456 & P0325 on my '98 Pathfinder, mileage ~200k miles. The vehicle ran fine for a year with them - now that I've decided to keep it, I'm repairing them. I pulled the hoses on the evap canister just behind the left rear tire and blew the debris out with an air hose. Then I soaked the interior of the mechanism they hooked to with WD-40. There's a electromagnetically activated prong inside that I assume can be gummed up and not release as it should. I drove it a couple of days to let it soak, then tapped it several times with a wooden mallet. The P0456 code has gone, and the moaning sound that used to happen after I shut the engine off has gone also. (I assume that was pressurized air seeping back past the blockage).
Now, on to the KS. I'll follow the excellent advice - gary3071, dan russ, and others - I've read on this forum. |

I did this relocation on my 98 Pathfinder about two or three years ago, and it's still running fine...

I finally got around to replacing my knock sensor on a 98 pathfinder. Took me 10 min (I took my time), saved the $800 my dealer wanted, and used the Dan Russell YouTube technique (1999 Nissan Pathfinder Knock Sensor Relocation (also works on Frontier & QX4) OBDII P0325 - YouTube). Worked perfectly, the P0325 code is gone. Thanks Dan & Gary.
Now to fix the P0335 code that's shown up..... |
