2001 kia sephia if the knock sensor is bad will it make the engine tap ?


It sounds like valve clatter. If you are also noticing black smoke from the exhaust, diminished engine response, etc then it has a faulty valve. I have to be honest. The Kia you have is not known as a good car. It was made before Hyundai took over for quality control. I would seriously consider selling the car while it still runs. I am sorry for this answer, but I own a 2012 Kia Optima and have heard service writer horror stories on the Sephia. Again, I apologize for my recommendation.

My durango 03 is knocking. what causes this sound. It didn't wanted to start, and I got it to start and the knocking sound appeared


Here is one if it sounds like it , It is a BROKE WRIST PIN ON THE PISTON ROD . PLEASE watch the video and compare . if it Sounds the same you will have to tear down the engine to see if it can be rebuilt or not ? If there is to much damage to that cylinder in the engine , the motor may be junk , and need to replace it ?
Good Luck !!!!!!!!!!!

Engine knocking


Well a low tone knocking noise at startup is usually a worn engine bearing.
You should be able to have someone listen to the engine to tell if it is coming from the top or bottom.

Knocking sound in Engine of Kia Sephia when driven longer.


It sounds like valve train noise. The best thing to do is have the dealer listen to it and see what the preliminary diagnosis is of the nosie. Is the engine full of oil and it has been changed on a regular basis or at least every 5,000 miles.

Engine knocking


what kind of car???
if your in a cold climat and your oil is dirty lifters will knock
till they fill with oil
i would change oil and filter
read your manual and put in the proper weight oil...ie: 5w30

fords are famous for pluging the oil filter on the 6 cyl. engines,thus reduceing oil flow to the upper engine

Engine knocks when you go in reverse why?


If it knocks when you go from Drive to Reverse or Park to Reverse than its usually a rear engine mount, Bushing or bolts to engine cradle under engine near firewall in center of engine bay towards passenger side. This is for a single or tourqe knock Which means the engine rotates too far and makes contact with a part of the engine bay it should not, or it is loose enough to make the sound.

Easier to notice in a stick shift car than a automatic test by setting Ebrake and putting car into reverse go from drive to reverse in idle with foot on brake if its knocking only when you go into gear this is the problem.

Unfortunately, it sounds like you have a spun bearing. This is a severe engine problem that reqiures major engine work, if left unaddress it will destroy your engine.
Please note I underlined "sounds like", you need to have someone check the engine to make sure.

Where is the knock sensor and how do you replace


The knock sensor is most likely ok you need to do a top engine clean to get the combustion chamber presure down so the knock sensor can ****** the timing enough to not knock or ping, You may not here the ping but the knock sensor does. Go to a GM dealer and buy a can of top engine cleaner warm the engine up and pull vacuum line off the back of the throttle body and allow it to **** the full bottle into the engine then kill the engine. let sit for 20 minutes hook up vacuum hose start the engine and rev it up to where it will still run let it run for 10 minutes till smoke clears out then take it for a test drive after you drive it 10 or 15 miles you should notice the check engine light not cumming on and the engine ill run smoother and the fuel millage will go back up, afterwords change the motor oil and filter to get rid of all the carbon down in the oil pan. If this does not fix it then change the knock sensor, it has 4 wires running to it and is on the side of the block left side. If you replace it be sure not to tighten it to tight if fact use a tork wrench to tighten it or you will break the ceramic disc inside the sensor.

Engine knocking.


Hi,my 92 prado started making a knocking sound recently,we couldn't pin it down to one spot in the engine.
The knocking was constant at low revs and then disapeared.
Turned out to be the tourque converter knob had bust of and eventually destroyed the fly wheel and the transmission pump.
Definatley check under top cover and also drop off the sump to check for loose nuts etc.
hope this helps.
