The grade (octane) of fuel you run as absolutely no physical effect on the knock sensor.

shhhhh, don't tell them that. The more money they spend the better the economy gets.

haaaaa wtf?!


is haynes correct when they say you have to remove upper and lower intake manifold to change out the ks??

That would be the hard way... Just shove your hand in the opening and use a ratchet or wrench..

Hi Everyone,
My check engine light indicates that my knock sensor and coolant temp sensor are malfunctioning. The problem with my '95 maxima is that it stalls a lot, even while driving. Could the knock sensor be a cause, or a symptom?

Thanks,

as far as i know a knock sensor will not do that, but a coolent temp sensor may if it is sending a signal to the ECU that your car is overheating, the ecu will try and correct the overheating and may even shut the car down, but that is very rare. there may be another issue that is not seen

desiboi

There is also a hole in my flex pipe, could that have an impact on the stalling? I put new spark plugs in last year, so I'm not sure if its a problem with the plugs.

I actually brought my car over to California from the east coast and much of the exhaust system is rusted - which makes replacing the flex pipe a little difficult. Aside from the noise and a lower fuel efficiency, what could the hole in the flex pipe do?

By the way, I've brought my car ('95 GLE auto) into a couple places, and no one has been able to tell me why the car stalls frequently!

Thanks,

- Neil

Its the Engine Coolant Temp Sensor that is stalling your car, AS some said above. Its a $20 sensor that goes in your upper radiator hose - 5-10min job tops.

ok back to the origonal post, do you mean to tell me that the cheepest Knock sensor we can get is $124 other than going to some no name on e-bay??

umm.. if you read the replies to the original post you would have seen a variety of genuine options for < $100, e.g. Pinnacle Nissan.

Geophrum

i just looked at pinnacle and it is $123.06.. unless there is another pinnacle nissan or there is a promo going on that i dont see

109.00 for oem and 89.00 for generic

JUST GET UR girlfriend or a small child TO STICK HER/his SMALL HAND in the cramped area- and viola, just remove the stupid delicate and expensive sensor, and avoid bleeding, bruising and scraping to your (not meant for removal of this sensor) guy hands. Oh and make sure they know if they drop it in the bay, u'll be forced to kick their butt.

on a 99 Max, when the ks goes dead does it illuminate the Check engine light. Reason is because I am having the sputtering feeling when accelerating from a dead stop. the only time the check engine goes on or flashes is when Im doing hard accelerating. I know that is caused by Ign Coils
Im wondering if my KS is bad also

njmodi

iTrader: (4)

No. The KS will not set the CEL by itself. Replace your coil packs, reset the ECU and see how the car drives. Check for codes in a few days (Even if the CEL is off) to make sure the KS code didn't post.

joematic

Thanks alot

likemick

What do the coil packs do? I am going to try this, as my CEL is flashing for the knock sensor and 'engine coolant temperature sensor'.

Attention MR. Newbie you donot post in other people threads your problems. However a blinking CEL indicated a cylinder misfire with your coilpacks. They are ina sense the rotors, wires and ignition coil all built into one. They are common failures on nissan maximas and most people will replace a few or all at 100k. You can get all 6 in a group deal for about 300 bucks and installation in very easy.

MadaF

any differences between oem or generic part?

wahoohead

Does a bad knock sensor cause or contribute to hard starting when warm? I found a genuine Nissan knock sensor on EBAY for approx 101.00 shipped/

Geophrum

Nope just the box it comes in.. i was told that they are actually made by the same company... only problem is not sure how meny if any the generic ones they still have left

jm272

I got mine off Ebay for under $100. OEM and works fine

jm272

Oh yeah, and I used a extra long pair of needle nose pliers to place the knock sensor back into position with the bolt in it. and then lightly tapped the sides of the bolt with a screwdriver until the threads caught on then tighten with socket. It would be good to have a magnetic pick up tool just in case you drop the bolt.
