Running hot or timing too far advanced
are you sure its not just cheap gas? try some premium or octane boost first. The knock sensor does not prevent engine knock, just senses it.
As you are looking at your truck from the front the knock sensor shoud be on the passenger side right under the manifolds
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.
Check the module under the distributor cap.
It is screwed into the passenger side of the engine block between the starter and motor mount. You will have to get under the truck to be able to see it
You would probably hear a spark knock or pinging under acceleration or load. Check engine light may come on also.
on top of the block. on the left side under the intake manifold.
the Spark/Knock Sensor is under the intake manifold. Driver side. Approximately 5-7 hour job.
Knock Sensor On your 1992 Toyota Truck Previa 2WD (2.4L FI DOHC), the Knock Sensor is located: Front seating area, center, under engine cover, passenger side of engine, under intake manifold, mounted in engine block
under the lower intake manifold
If you slide up under the passenger side of the truck behind the front wheel and look up at the side of the engine You will see the starter, Just in front of the starter and screewed into the side of the engine block is the knock sensor. It will be round and have an electric wire pluged into it.
They are under the 6 ignition coils. There is a coil for each spark plug. You have to remove the coils, and then remove the plugs.
Yes it does and it is called a knock sensor.The V8 engines have 2 knock sensors and thay are under the intake manifold. You will have to remove the intake to get to them.The V6 engines have only 1 sensor and it is screewed into the top rear passenger side of the engine were the transmission bolts to the block. It is just under the oil sending unit.
iF YOU SLIDE IN UNDER THE TRUCK BEHIND THE PASSENGER FRONT WHEEL AND LOOK UP AT THE BOTTOM SIDE OF THE ENGINE, YOU WILL SEE THE STARTER. NOW JUST IN FRONT OF THE STARTER A FEW INCHES YOU WILL SEE THE KNOCK SENOR SCREEWED INTO THE SIDE OF THE ENGINE BLOCK. iT CAN BE HARD TO SEE.
Answer Difference tune for propane thanThe only diffence is spark plug gap .34 instead of .45 or .60 propane needs a hotter spark other than that it,s the same. Hope that helps you TJ I would adjust the timing for best performance without more than a bit of knock under maximum load. I recall that with propand you can run LOTS more compression.
There are 2 of them and they are both are up under the intake manifold. You will have to remove the intake to get to them are even see them.
The Knock sensor is located under the intake manifold... in between the Engine Main body and Spark Plug Housing... Its easier to see when the Air intake system & battery housing are removed look down into the crevices...
it was rumored that a mew is under the truck
the knock senser is located on the right side of the motor(drivers side) beside the oil pan, under the exhaust manifold. Only seen from under the truck. When you remove it be careful coolant will come out of the threaded hole the senser goes into.
It is screewed into the passenger side of the engine block just in front of the starter. You will have to slide in under the truck on that side to see it.
the knock sensor is under intake, must remove intake and it is under two coolant lines.
There are two knock sensors located under the midpoint of the heads, under the center spark plug, partially coverd by a heat shield. They are screwed in vertically and must be accessed from below. WARNING: Before you remove a knock sensor, the engine must be cold and cooling system properly drained. Steam or hot coolant can cause severe injury and burns - coolant is toxic.
This is spelled out in your owner's manual. It is also listed on a placard under the hood. .033 per chiltons manual
under the intake. in the valley. 2 knock sensors actuallly
I own an 02 Highlander, and sometimes I get a knock when engine is under load, like going up a hill or when accelerating. This is engine knock caused by low octane gas. When I use a mid grade or premium octane, I do not get the sound at all. .
