Is it metalling sound ? if that's the case then don't drive it .. you might be having issues with connecting rod or the bearings in the both cases engine will seize. Consult a auto technician, but you wont have engine light on due to this.
If it is knocking due to misfire (which is mostly the case as the engine light is also on) .... than find which cylinder have the issue then clean or replace the spark plug. If you can get a scanner to read the car computer it will solve the issue in a blink. Otherwise start the engine ... open the hood .pull out spark plug connector one by one and notice the change in sound... the one that is bad will have no effect on the sound.
Sorry absolutely no idea with my head under the bonnet -hood- Now has the opil been changed regular like every 5/6000 miles if its gungy and old then chances are you have knocked a big end out or two ,best advice is to trade it in quick whilst it still runs
a knock sensor is basically a resistor and a spring, and what it does is it reduces valve ping. Valve ping is when the fuel is not properly burned and tries to explode before the valve is fully closed and it will make a pinging noise when under load or at higher RPM. If the sensor is bad it can cause detonation, detonation is when the fuel explodes before the valve is closed and can cause a cracked, or exploded piston, bent valves etc. Your problem does not sound like that of a bad knock sensor, predominantly you will only hear the "ping" under load and not at idle and if it was bad your check engine light should be on. this sounds more like a rod knock. change the oil again and use only AMSOIL and an amsoil filter, amsoil is proven to last longer than any other oil, 600,000 miles without a change, or a filter change.
Its probably lifter noise,check what grade of oil is in the car or change it to a slightly thicker grade,i would expect that the car has a lot of mileage on it,if the oil light goes out quickly on the dash when starting its not the oil pump(very uncommon),knock sensor is for ignition timing to stop pinging,nothing to do with your noise,generally its engine wear
Hi there... I would not recomend driving your vehicle. there is a possibility that the knock you are hearing could be the lifters. What weight of oil was put inot your vehicle? could be that thw viscosity is too heavy for the temperatures your are experiencing. The engine light could be the knock sensor that has detected the knocking in your engine. Your best bet is to have the vehicle towed to a shop and have them check it out. worst case senario is the oil pump. If you drive with no oil pump you could do great damage to the engine. Hope this helps you out.
Therre is no DTC code "5". The DTCs start at 12. If the knock sensor (there are actually 2) was bad, you would have an acceleration issue. The knock sensor changes the timing of the spark to eliminate detonation, or "pinging". Do you have a "Ping" condition/valve rattle on acceleration?
To reset the light, open the hood, remove the 15 amp EFI fuse for 5 minutes. Replace it, and start the car and drive it until it reaches operating temperature. If the light comes back on instantly, you have a bad sensor or a bad wire.
