It is POSSIBLE, but highly unlikely unless you had prior problems with the timing. I would have it checked out by a mechanic as it could be any number of things.
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.
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.
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.
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.
Engine tappets
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.
