The sensor is located in the lower part of engine block, it goes into the water jacket of the block, so dreain the system before you remove it, get a new one before you look for it so you know what you are looking at while under the truck.

I have a 95 oldsmobile 98 regency elite I cant find where the knock sensor goes I have a haynes manual but where it shows it wont go


Well, for starters, your problem got posted under 1985 Oldsmobile 98 - then you said it was a 95 Oldsmobile 98 Regency Elite (HUGE difference between 85 and 95)...then it would be REALLY nice to know which engine we are talking about.

I'll just go with what you said last: 1995 Oldsmobile Regency Elite (Two engine possibilities)

If you have the 3.8L Supercharged engine (VIN CODE "1") it is on the left side of the engine near the oil filter.

If you have the non-supercharged 3.8L (VIN CODE "K") there are TWO of them. One is near the oil filter and the other one is in about the same location on the other side of the engine block.

Please also note that MOST fault codes for knock sensors are not caused by the knock sensors themselves. (they do fail, but it is very rare.) Usually there is either a wiring problem to the knock sensor, or the engine has internal problems causing a "knocking" or "ticking" noise which causes the engine computer to "think" that there is a problem with pre-detonation causing an "ignition ping". The code sets when the computer has retarded the ignition timing as far as it can and the "knock" or "ping" does not go away....usually it doesn't go away because it is not caused by ignition timing. The knock sensor is just doing its job and reporting the knock. It does not know the difference between a knock caused by ignition and a knock caused by internal engine problems.

How to replace the knock sensor on a 2004 cheverolet 2500 6.0 liter engine


Hello Friend:

Your Anti-Knock Sensor is Located With Hood Raised Facing the Engine Compartment,Its on the LEFT SIDE Right Under your Exhaust Manifold Towards the Back.

On the Engine Block ,You'll see Your Anti-Knock Sensor Wires running to it.

Its a Little hard to Get to but Not so hard that you can't do it Yourself.

Disconnect the Wire Connector, And Take a Good Look at the Wires,Since it Runs so Close to your Exhaust you could have Also some Faulty Wiring going to the Sensor.

Just Un Screw the Anti-Knock Senser and Replace New.

This will get your Anti-Knock Sensor Replaced With A New One Like i Said Look very Good at the Wiring Going to the Sensor.

Thanks for using FIXYA Please let me know how i've helped you by Voting and If you Would write a Small Testamony.

Thank You: From d_hubbs

V6 3.3L The sensor is located underneath the air intake manifold on top of the engine block. This should take an experienced mechanic about 3-4 hours to replace.

Knock sensor dont work for 2005 dodge durango


this problem is very seldom the knock sensor, it can be the harness connector at the sensor or the engine has excessive knock which will set a code, u did not mention the particular code so hard to say, the location of the knock sensor is the lower section of the engine block, it is screwed into what would normally be a block drain plug, if u replace it u need to torque it to whatever the factory spec is or it can cause it throw another code..

Need to find location knock sensor for replace


I know that the knock sensor for a 1998 Quest with a 3.0 is located on the passenger side of the engine compartment under the intake manifold. You should be able to find the wiring and connector next to the intake manifold. To access the sensor, you have to remove the upper and lower intake manifold. The sensor is on the block between the heads. Hope this helps.

Knock sensor code, p0330


The knock sensors either work or they don't. When they do not, the light comes on. All that a knock senor is is a piezo crystal that vibrates at the frequency that is comparable to engine "knock", and sends that yes/no signal to the ECU. There are 2 knock sensors, and both are bolted to each side of the engine interior walls, under each cylinder head. You have to remove both of the intake manifolds to access the knock sensors and their wiring.
Price to pay? My flat rate book suggests 3.7 hrs to change both. 3.7 hrs times your local labour rate, plus the price of the 2 sensors and/or wiring, and the price for the gaskets for the upper & lower manifolds. Depending on your location, you could quickly spend over $500.00.
