What are the symptoms of a bad knock sensor and can it damage the engine?
you will have a knock sensor code and the car will run slugish. when a knock sesor code is set its retards the timing so the engine will not detonate. the easyiest way to fix it is relocating the sensor.
A knock sensor is a device that senses detonation. Detonation occurs in the engine when the fuel begins to burn prematurely; it can cause substantial damage to the engine.
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 cuts the engine out so it won't damage the car if not replaced, the car just won't work.
A knock sensor is a piezoelectric device that senses the knocks produced in the engine. The knock sensor tells de computer to retard the timing in order to prevent piston damage and/or blown head gaskets.
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.
You can drive the car but if the engine should ping (knock) under load, the knock sensor won't be able to tell the computer to retard the timing. Excessive pinging can damage internal engine parts.
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… Read More
Allowing an engine to ping excessively can do serious damage.
If your car would run lean the sensor would not be able to determine that and their could be engine damage.
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.
There are no symptoms. The knock sensor is a passive part that does not do anything if it's not activated. Knock sensors codes on the Villager/Quest are usually caused by some other component, not the sensor itself.
You could do it with a resistor but this is a very bad idea as that sensor is there to protect the engine from catastrophic damage. Source a replacement from ebay
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.
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.
A knock sensor listens for the 'knock' (or pinking), that shows that the fuel is exploding, rather than burning. Via the engine management computer, it retards the timing of the spark, until the knocking stops. 'Knocking' can damage valves and piston crowns, if allowed to continue. A knock sensor allows different grades of fuel to be used, without damaging the engine.
If your refering to the engine knock sensor, it is moounted in the side of the cylinder head and has a single wire connector. try not to damage it when removing, it is a piezo electric device and is vulnerable to impact.
A knock sensor is a sensor inside an engine that detects detonation of fuel prior to the spark plug igniting the full during the cycles of the engines. Detonation at the wrong time can cause significant harm to an engine since it will cause the piston where the detonation occurred to be pushed down at the incorrect time. This can result in a catastrophic breakdown of the whole engine. A knock sensor monitors irregular detonation… Read More
There is no "knock sensor" on a 4.0L engine
This is controlled by a knock sensor.
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.
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 on Bank #1 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0327… Read More
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 will not. If you have a knocking sound then you have trouble inside of the engine.
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.
The knock sensor is a passive device that has no effect on engine idle.
The knock sensor is located on the side of the engine block near the bellhousing
knock sensor position
your knock sensor could need to be replaced
No. It only senses engine vibration/knock.
Any way to temporarily repair plug for Knock sensor on 1993 Chevy blazer k1500 to get it to start to get it home?
You have another problem other then the knock sensor if the engine will not start and run. A knock sensor will not cause the engine not to run.
Sure, go ahead. New engines aren't all that expensive. If your knock sensor is giving a true reading, you are probably using a fuel that does not meet the octane requirement of your engine. Could you possibly have filled up with 85% ethanol? If you continue running the engine while it is knocking, you will damage the pistons and experience run-on or dieseling. If your knock sensor is giving a false reading, you won't experience… Read More
The knocking sound that the sensor is designed to detect is caused by uneven combustion of a lower octane gasoline than the engine is able to burn efficiently. The knock sensor signals the Electronic Control Unit and ignition timing and other engine parameters are changed to eliminate the knocking. Knocking, if allowed to continue over a long time can seriously damage the engine. --Ken
Year, make and model would help, but generally...no. Unless the knock sensor were actually loose (not bolted down or broken) and "banging" off some other part, but this is a very unlikely scenario. Knock sensors are design to detect exactly that, engine knocks. There purpose is to have the vehicle's computer reduce timing, adjust fuel ratio and/or possibly shut down the engine completely if the sensor detects a knock that could result in engine damage.
where is the knock sensor on 2003 kia Sedona answer knock sensor is mounted on the engine block near the intake manifold with a wiring harness attached to it.
Nothing. The knock sensor is a passive part that will not affect how the engine runs.
the motor could pre-detonate or "knock" that can cause damage
If you have the 7MGE engine: Then the knock sensor is screwed into the engine block, directly underneath the intake manifold.
89 toyota pickup v6 engine anti knock sensor location
The knock sensor is on the side of the Escort engine block. It is located close to the oil sensor.
Knock sensor is located on the side of the engine facing the firewall. There is only one sensor at that side.
A knock sensor detects engine knock in the motor(aka pinging, detonation, or uncontrolled explosions. it basically means the motor is about to blow up or potentially could.) the second part to a knock sensor is that it keeps the ignition timing as advanced as possible to make the most power without making engine knock. So if you have a bad knock sensor or have a check engine light form a knock sensor your car will… Read More
