Best Answer

It means something bad is about to happen to the engine. Take it to a garage. 1. check your oil first 2. If oil is right, check oil pressure. 3. If oil pressure is not right your oil pump is going out. other than that, a knocking generally means a bad main or crank bearing.

It usually happens in high mileage engines that have excessive wear to the main bearings (which causes the knock) and too much wear to the oil rings on the pistons (which causes the smoke).

What does the engine code knock sensor mean?

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
