That depends on the cause of the knock.
Many people are incapable of discerning the difference between ignition pinging, a true "knock", and lifter noise.
Lifter clatter can only be adjusted by a machine shop.
If it's a ROD knock, that's only caused by too much clearance between the rod bearing and the crankshaft. In that case, the only option is to rebuild the engine.
Same with main bearings, too much clearance between the main bearing and the crankshaft will cause a deeper knocking sound, but the cause, AND REPAIR, is much the same.
However, it is possible to SOMETIMES use an oil with a higher viscosity to squeeze a few more miles out of an engine. That only works if the engine hasn't worn too badly.
Another cause of engine "knocking" is when the spark fires too early.
The "knock sensor" detects cylinder pinging and sends a signal to the computer, which then retards the spark making the pinging go away. The idea is that the computer keeps the spark timing as far advanced as is possible without introducing cylinder pinging. Doing that can significantly increase fuel economy. It's called a knock sensor, even though we typically call early ignition "pinging".
The computer should be able to determine if the knock sensor has failed. A computer diagnostic code scan will give you a good idea if any of the electronic components have failed.
No. It only senses engine vibration/knock.
No it will not.
To stop spark knock , try a higher octane fuel. Make sure that the engine is timed properly and that the spark plug type isn't considered too "hot."
No, That part will not shut the engine down
the only sign is if it goes bad it should trigger the check engine light, you wont notice loss in peformance in engine. all it does is when there is a knock in a cylinder, from bad fuel, it leans back on fuel to stop the knock.
There are some engines that will "KNOCK" if the wrong oil filter is used but in most cases the engine must be disassembled and repaired
Add oil.
You may have blown a head gasket. Stop driving it until you can find out.
stop using 87 and use 91 only that's why ur knock sensors is activiated ok ur car has a high performance engine i blew my q 45 engine out by using 87

No. The knock sensor alerts you to the fact that there is an engine vibration that needs attention. Mine has been awaiting replacement for six months.
The engine is overloaded in case it of generator set or any other load and in case of a car the vehicle is not engage in lower gear as per load and engine rpm.
