Can a faulty knock sensor make your car have no spark?
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.
if its not that and its not turning then its the starter. if its not that then it can be the spark plug make sure its not wet
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.
Should be on the side of the engine block with one bolt and wire harness. Make sure you really need this as they are not cheap! Make sure your fuel is good your sparkplugs are in good shape, (iridium ngk). Make sure your timing is correct. If all of this is correct and you are still getting a knock sensor code then you may need to replace it. Note: they do not usually go bad… Read More
The knock sensor is a passive device that has no effect on engine idle.
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 faulty crank sensor would make the engine not run.
The knock sensor has no effect on idle. It has no effect at all unless it is triggered by detonation. It is a passive device.
what will happen if you install a knock sensor that isn't called for that make & madel
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 you follow Jeeps recommended gap the knock sensor activates and it knocks. Just gap to .060 - 075 " and make sure to have plug cap bar on correct. so knock disappears. WTF
What is a temperature sensor on a 1997 Subaru Outback and will it shut your car down or make it difficult to start when it is faulty?
the temp sensor opperates the choke flap , and if the sensor is faulty the choke will stay open and make it difficult to start, and on cold mornings some times make it impossible to start
Misfire is usually caused by faulty wires or spark plugs or both. Throttle position sensor failure generally causes poor response to the throttle. That is poor acceleration, slow to return to idle and rough idle.
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
if a knock gos bad can your car go off
Nothing. The knock sensor is probably NOT faulty. The knock sensor is in the engine V under the intake manifolds and coolant crossover pipe. As it requires considerable disassembly and an expensive new gasket set to reach it, I suggest you make very sure there is something wrong with it first. You will have to remove the upper and lower intake manifolds and coolant crossover pipe assembly to reach it. Just because you are receiving… Read More
could be numerous things, like a faulty oxygen sensor/a.k.a O2 sensor, a faulty mass air flow sensor. it all depends on what year make and model of vehicle we are talking about
A faulty fan motor, A faulty fan motor relay, A faulty coolant temp sensor, A faulty ECM, (most unlikely),
A faulty oxygen sensor can make a car smell like gas. Oxygen and gasoline mixing wrong can cause excessive pollution. Replacing the oxygen sensor can correct this issue, and improve the gas mileage in the car.
Yes, it prevents knock and detonation. The knock sensor is just a sensor it only pulls timing after knock aka damage occurs. One tank will be fine but don't make it a habit.
No it will not cause it not to run.
Yes, a faulty coolant temp sensor can do that.
No. The knock sensor alerts you to the fact that there is an engine vibration that needs attention. Mine has been awaiting replacement for six months.
If you run your rig with a bad knock sensor the computer will not be able to tell if or when your engine starts to knock (such as a rod knocking). That is if it isn't already cause the sensor is there for insurance. Make sure the sensor is bad and if so have it replaced asap. It is an expensive job cause you have to remove the intake to get to them (some engines… Read More
That is True.. A faulty speed sensor will cause no shift or late shift..
Faulty sensor get it replaced if not check to make sure wire isn't shorting out
No. It may run poorly but it will start and run.
Could be,worn spark plugs, bad spark plug wires, vacuum leak, contaminated fuel (water), faulty fuel pump, faulty fuel pressure regulator, faulty fuel injector(s), more info such as the year, make, model and engine would help.
No it will not. Has nothing to do with engine knocking. You need to define the word KNOCK. Need to ask your question again. THANK YOU.
The Knock sensor is located on the lower side of the engine near the oil pan rail and goes into water. Make sure your engine is cool before you start the job. The best way is to drain all of the coolant out of the engine first, then disconnect the wire, then remove the knock sensor. WARNING--antifreeze will come pouring out when you take the knock sensor our so WEAR SAFETY GOGGLES to protect your… Read More
i been working on cars 20 years i haven't seen a knock sensor make a car miss it;s job is to ajust timing i have seen it set off service lights why would you think it's a knock sensor if i knew more infoe i might be able to help you
No, That part will not shut the engine down
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"… Read More
It retards / slows the engine timing up when it detects an engine knock / pining noise like bad fuel are valve noise.
If a 1994 Trooper loses power going up hill and has a spark knock in the engine, the compression of the engine should be checked. It is possible that the vehicle is not running on all of its cylinders.
yes but the cam sensor and the crank sensor work to geather so make sure to have it tested if you can to make sure wich is bad .
It really depends upon the car. But the basic function is this: What the knock sensor does is if there is a knock being created by the engine, the knock sensor picks it up, and sends a signal the the computer telling it that there is a knock. The computer then calculates what to do in means of how much fuel should go in or how much air should go in. The right amount of… Read More
LoL, sorry it is the knock sensor itself. Yota tech has more on the subject. The knock sensor is located SW of the oil filter and just a little to the right of the fuel filter. You probably have a bad connection so you may want to pull the wire clean it and the connector and you should be all set. Make sure to check along the wire too to make sure it hasn't torn… Read More
Check engine light on The garage says its the o2 sensor if there is more than one how do you tell which if faulty Would a faulty o2 sensor also cause it to run very lumpy?
make sure your gas cap is secure, I know it sounds crazy, but you would be surpized.
yes but if it is a blown head gasket it will make it miss and put steam and some water out the tell pipe if its not doing these things then check your anti knock sensor
Could use more info such as year, make, model, engine and if it has a carburetor or is it fuel injected. More info.....Here is a list of the most common causes of engine hesitation during acceleration: bad spark plugs bad spark plugs wires a dirty fuel filter a dirty air filter a bad carburetor dirty fuel injectors Faulty vacuum advance vacuum lines incorrectly routedincorrect timing vacuum leak(s) incorrect fuel pressure (fuel injected) faulty accelerator pump… Read More
It depends on if it won't "crank" or wont't "start" if it worn't crank make sure your battery terminals are clean and tight if it still won't crank check the wiring if it looks ok suspect the starter. if it won't start it could be a fuel pump fouled spark plugs faulty ignition module faulty crank sensor or out of time. hope this helps.
got no idea, need to know the year, make, model and engine size to help you.
check engine is an emissions component fault, and is not related to your spark plugs...get the codes checked and replace faulty sensor... read up on diagnosis.. Everyone should have a manual for their vehicle, and the local library should have a professional shop manual available to make copies of for FREE...make the time to take time to read up on your vehicle, and work like the PRO'S! Good luck :) Dave Diagnostic Trouble Codes (DTC)… Read More
depends on what kind of car it is. On most supercharged, turbocharged,and cars with high compression ratios the knock sensor code would come up because you didnt put high octane fuel in the car. the lower the octane rating of the fuel, the more unstable the fuel is under pressure, which means the fuel would ignite before the spark ignites it, causing the timing to be off and the Check Engine lite to come on… Read More
Engine overheating could be caused by several reasons. Some of them are, thermostat, faulty fan, faulty sensor, bad rad., blockage somewhere, water pump.
17.4 ft-lb. - and make sure you put it back at the same angle the old sensor was.
A common problem with GM vortec engines is that they dont seal the knock sensors very well and moisture gets into them. the fix is to replace the sensor, and build a dam of rtv silicone around it, keeping water out.
The electric cooling fan or cooling fan temp sensor may be faulty.
Make your way to the front of the engine, remove the plastic v-belt cover from the power steering pump inlet, the sensor sits just above the crank pulley. There's a plastic plug with two wires which needs to be pulled out from the knock/crank sensor. Then use a small spanner to loosen the 2 screws on either side of the sensor.
