Nissan murano knock sensor reset

Have an 06 murano with about 55000 miles that i bought recently. And not knowing i did used 87 octane fuel and started to get the knock in the engine only under load or accelerating not when idling or in neutral. right away i switched to 91 octane and used so far two tanks but still hear the knock. My question is how long it will take for the knock sensor to detect and switch back? Is there are anyway that i can restart the sensor? By the as soon as you drive the vehicle for longer time like 30 min the knock goes away or it's still there but its not that loud at all . Please help with this thanks

If the knocking did not go away with the higher octane fuel then you may have other problems. A dirty fuel injector oor a misfiring spark plug can also cause knocking in a modern car. A faulty sensor may also be causing the wrong fuel / air mixture in the cylinder... check out the cheapest fixes first.

Been using 87 octane in '02 maxima for 1yr. have replaced oxy & nkock sensors. Is this due to low octane?


Ok the 2002 Maxima 3.5 requires premium fuel 91 octane. According to the owners manual for optimum performance use 91 octane, you can use 87 octane unless you get pinging sounds. Sounds like you just need to use the proper octane. Occasionally I will run regular 87 and can really feel a loss of power. When I use 91 octane the car is a rocket ship.

What kind of gas does a maxima 2001


According to page 10-3 of the 2001 Nissan Maxima Owner's Manual:

FUEL RECOMMENDATION
Unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96)
If unleaded premium gasoline is not available,
unleaded regular gasoline with an
octane rating of at least 87 AKI (Research
octane number 91) can be used.
However, for maximum vehicle performance,
the use of unleaded premium gasoline
is recommended.

Engine "knock" is not just an unusual sound - but over time can cause real damage to the engine. You *should* use fuels with the recommended octane levels, but if you choose to use fuel with a lower octane level due to reduce fuel costs - do not repeatedly use fuel that causes engine knock. Find the "sweet spot" between the cost of lower octane fuel and an octane level that does not cause knocking. Expect fuel economy and performance to drop with lower octane fuels, too.

Good luck!

Knock sensor code just came up 56,000 miles.recently added octane boost to fuel system. wondering if that cused my problem or just a faulty sensor


Since the code came up since adding the octane booster, I would say that is the problem. If you don't hear a knock coming from your engine, wait until you are at about a 1/4 of a tank and fill it up. This problem should go away on it's own.

What type of fuel does it run. 87 89 91


You should be able to run the cheapest, low octane you can get, including e15, or more if you want. The only thing to watch for is knocking and pinging, most of these were made to run on low octane, but if they ping, you may need more umph. I have a couple of Nissans, no problem with pinging or low grade fuel.

Knocking/tapping when accelerating on 2003 nissan x-trail td


Usually an indication of Bad fuel, needs a tune up or Slipped Timing. Most likely bad fuel or tune up depending on when the last time you replaced the plugs and wires was. If you have been using the 87 Octane low grade fuel that would cause this or if you happened to get some bad fuel at a station. The vehicle will run on 87 octane but was designed to have a minimum of 89 octane fuel, the mid grade. If you haven't replaced your spark plugs in the last 25,000 miles replace the spark plugs and wires. If you suspect the fuel is the issue you can get injector cleaner or Octane boost and add to a FULL tank of gas to clean it out.

I have a r33 skyline and if i give it full throttle it pings but not at 3/4 throttle? how do i fix it?


What fuel are you using? If you are normally running 87 octane and it's pinging, try a higher octane for a while. I know it's still pricey but some cars require the higher octane. It may take a few hundred miles to run all the 87 octane out of the system so try running for a month on Super. Just a suggestion. Hope it helps.

Hello


You can use 87 octane, but first let me give you some food for thought, when you use lower octane than recommended the knock or ping sensor will ****** the timing to accommodate the lower octane fuel and prevent piston damage, this causes a loss of fuel economy and power, so the real saving is very small if at all, but yes your car will run fine in all but very hot climates, like the southwestern states. I hqave a Corvette, it calls for 91 Octane, I have run 87 in it to save money, but the fuel mileage drops 3 MPG, so I gave that up.
