It retards / slows the engine timing up when it detects an engine knock / pining noise like bad fuel are valve noise.
The knock sensor just advances and retards the engine timing only. If there is a noise in the engine then you have engine are valve train problems. The knock sensor will not make the engine knock.
The knocking noise is commonly called spark knock. The knock can be called by the engine timing not being set correctly, or using gas that has too low of an octane for the engine.
It is located on the side of the engine block. The purpose of the knock sensor is to retard engine timing When there is an engine noise. It is a rare case that one ever goes bad.
It is located on the engine block. A knock sensor will very seldom give a problem. It detects engine noises and retards to timing. If you have a code then you need to find the noise and repair it.
You can't, its done by the computer if you have a knock noise, replace the knock sensor. its locate on the back of the engine near the alternator.
No, there will not be engine noise, but you may notice a decrease in engine performance. The 1.9 liter engine is a freewheeling engine which is not damaged by incorrect camshaft timing or even by a broken timing belt.
The knock sensor is exactly what it says. It senses any knock or ticking in the engine and retards the timing. The knock sensor is not the problem, the knocking is. Go to a repair shop and have it diagnosed.
The noise ie engine due to bad quality of petrol
It is called "pinging". This happens when the ignition timing is out. The timing needs to be set by a mechanic to eliminate this noise. I would help also if we knew what year, make and model vehicle you have. Depending on that, it could be a knock sensor gone bad.
Most likely cause-valvetrain noise, check oil level, pressure, also possible engine knock. If you have a knock sensor, mil should be illuminated
Low oil pressure, engine knock / noise.
An engine "knock" will become more pronounced when engine is labored (climbing a hill) Valve noise will remain the same under stress
AnswerI think this engine uses a timing chain, but I am not 100% positive. Regardless, the noise you are hearing is either a timing chain that is loose or a belt. I would suspect that the timing chain is loose. Have this looked at ASAP.It could also be the timing tensioner also.
Year, make and model would help, but generally...no. Unless the knock sensor were actually loose (not bolted down or broken) and "banging" off some other part, but this is a very unlikely scenario. Knock sensors are design to detect exactly that, engine knocks. There purpose is to have the vehicle's computer reduce timing, adjust fuel ratio and/or possibly shut down the engine completely if the sensor detects a knock that could result in engine damage.
An "engine knock" will be more noticable when engine is labored (climbing a hill etc.) Valve noise will remain constant
You didn't specify which engine you have. The 3.0L engine has a timing chain, not a belt. If it isn't making excessive noise, then leave it alone.
For longer life with less maintenance, the Sentra engine uses a timing chain instead of a cheaper, but quieter, timing belt. You don't notice the extra noise generated by the timing chain.

A timing chain normally will last as long as the engine. Signs of a failing timing chain are chain noise and or engine that continues to jump time.
Serious engine knock or valve train noise. Have this looked into by a pro.
It is located on the side of the engine block. If you have a code for a knock sensor and you have a noise in the engine, it will set the code. That does not mean that the sensor is bad. They very rarely give problems.
The Ford Taurus does not have a timing belt, it has a timing chain. The timing chain is designed to last the life of the engine, and does not need routine replacement.
you would experience a pinging "metalic noise" under heavy or rush acceleration, would also have lost of power. this problem will not turn the check engine light.
Depends on the sound of the knock. Could be main bearings or rod bearings.
