If it is making a noise like a spark knock, maybe it is a spark knock.
No. The knock sensor's purpose is to detect spark knock (pinging) and send a signal to the ECM to temporally retard the timing until the spark knock stops.
The knock sensor detects spark knock or ping.
Severe spark knock (pinging) can damage the engine. Knock sensors detect spark knock (pinging) in the engine. They send that info to the ECM (Engine Control Module). The ECM makes temporary adjustments in engine timing to eliminate the spark knock.
Spark plug knock on a 1998 Chevrolet pickup is an indicator that the ignition timing is correct. By adjusting the timing, the knock can be eliminated.
knocking as in spark knock? or engine knock? spark knock is adjusted through a knock sensor via ignition timing. eng. knock is due to brg. knock as in low oil pressure or sluge in engine or just a tired motor
yes when it is not working properly
They help control spark knock and the damage they can do.
The knock sensor detects spark knock (aka ping), sends that signal to the engine control module (ECM), the ECM retards the timing until the spark knock stops.
The knock sensor sends a voltage pulse to the computer whenever it detects the vibrations caused by metal, such as the conditions caused by the spark knock. When the knock sensor sends a voltage pulse, the computer retards the timingin an effort to stop the spark knock.
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."
If the knock sensor failed the CEL (Check Engine Light) would be illuminated and the engine may "ping" or "spark knock" under load. Serious "spark knock" can damage the engine if allowed to continue.
The knock sensor detects spark knock (ping) and sends that info to the ECM. The ECM makes timing adjustments to stop the ping.
It changes the TIMING.
It detects spark knock (ping) then sends a signal to the ECM to retard timing.
the knock sensor monitors preignition,spark knock and sends signal to pcm,pcm responds by adjusting ignition timing and fuel timing until knock is gone.
are you sure its not just cheap gas? try some premium or octane boost first. The knock sensor does not prevent engine knock, just senses it.
The knock sensor detects spark knock or ping and sends a signal to the vehicles putor. The putor takes that information and retards timing in an attempt to eliminate the ping.
Electronic spark control is not receiving sinal from knock sensor Try replacing knock sensor
The knock sensor on a Passat is located on the side of the engine. It is just below the number two cylinder spark plug.
Try using higher octane gas if that doesn't do it then you may need to replace your knock sensor
when u have to much air going in the cylinder and it is blowing the spark out on the sparkplug like lighting a lighter and blowing it out.
Worn spark plugs would cause mis-firing or non firing cylinders, both are no good for the engine, replacing the plugs may stop the knock (Could also be a different problem) But you should replace spark plugs as soon as possible.
ESC stands for Electronic Spark Control it may also stand for Electronic Stability Control. The Electronic Spark Control module will retard the timing if it detects any spark knock or pinging or even other similar sounds made by the engine such as lifter knock.
EXSESSIVE amount of calcium is called hypercalcemia
