possible low oil
a lot of times its your timing belt, if its more of a knock its could be a rod knock
your knock sensor could need to be replaced
It's time for a new engine.
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.
This is controlled by a knock sensor.
I have a recent engine knock on my 91 escort started out intermittant. I have a recent engine knock on my 91 escort started out intermittant.
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
NO it will not. If you have a knocking sound then you have trouble inside of the engine.
The knock sensor has failed and you need to replace it with a new one in order for the check engine light to go out.
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.
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.
A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. The knock sensor generally threads into the engine block. This code may show up intermittently or the Service engine light may be lit constantly. You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms. * The knock sensor is faulty and needs to be replaced * There is a wiring short/fault in the knock sensor circuit * Check the resistance of the knock sensor (compare it to factory specs) * Check for broken/frayed wires leading to the sensor * Replace the knock sensor
