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.
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
The knock sensor, in your 1997 Chevrolet Lumina, can be found on the front of the engine. The knock sensor is near the top of the engine.
Yes it can hurt your engine to drive with a bad knock sensor. The knock sensor should be replaced as soon as possible.
The 2006 Dodge charger knock sensor is located on the back of the engine. The knock sensor will be near the bottom of the engine cover.
You can run a diagnostic test for the knock sensor, on your 2005 Chevy avalanche, by hooking the engine up to a diagnostic tester.
There is no "knock sensor" on a 4.0L engine
This is controlled by a knock sensor.
NO it will not. If you have a knocking sound then you have trouble inside of the engine.
The circuit 1 knock sensor would be located on the lower right side of the engine block (passenger side). You will need to drain the coolant from the radiator and be prepared for the passenger side of the block to drain coolant when the knock sensor is removed. After you disconnect the electrical connection to the knock sensor, the knock sensor simply unthreads from the block counterclockwise. Apply a thread sealant to the threads of the new sensor and install, no need to over tighten, this is a tapered pipe thread.
A bad knock sensor would illuminate the check engine light and allow the engine to ping (spark knock). The engine doesn't shift, the transmission shifts.
The knock sesor is located, on your Isuzu 1290, at the front of the engine. The sensor screws into the engine. Wires connect the sensor to the senor light.
No. It only senses engine vibration/knock.
where is the knock sensor circuit #1 location on a 1999 trans am ls1, I have looked everywhere. thanks
The knock sensor retards the engine timing when there is a knock or ping detected. This will make the car a little sluggish. It is rare that the knock sensor goes bad.
The knock sensor is located on top of the engine block underneath the intake.
your knock sensor could need to be replaced
The knock sensor is located on the side of the engine block near the bellhousing
knock sensor position
The knock sensor is a passive device that has no effect on engine idle.
"Knock Sensor 2 Circuit High Input (Bank 2)" A knock sensor prevents the air-fuel mixture in your cylinders from igniting before the spark plug goes off. Knocking usually occurs when you have a high-compression engine using low-grade gasoline. Always use the manufacturer-recommended grade of gasoline. Since you're only receiving the knock sensor code for the second bank of cylinders, most likely your knock sensor wiring or sensor is malfunctioning. Engine "knocking" sounds like metallic pings coming from the engine. If you don't hear that, then it's just your sensor.
No it will not.
There are no symptoms since the knock sensor doesn't do anything unless the engine is detonating, in which case it would do nothing and you would hear it. The knock sensor code is often tripped when there is a fault in something else since it's part of the same circuit. This is considered a "ghost" error code.
knock sensor is a very sensitive small microphone usually on the engine block or sum times on the cylinder head , it listens for any pre detonation going on in your engine . pre detonation is nasty early combustion you dont want, if you get pre det it causes a pre knock sound which the knock sensor microphone detects. your probly not getting pre detonation but thats what the sensor does 8) "sensor 1 circuit" means the ecu has detected it cannot make connection to the sensor, the sensor could be dead or you could have a wiring issue to the sensor IE chaffed wire, bad connection at the plug ect.
