The Knock sensor is a actual microphone screwed into the engine block. It is tuned to listen to the exact frequency of an engine knock, which is a high frequency ping. A failing knock sensor will cause all sorts of problems to engine operation, such as skewed timing controls, loss of performance and power and ever the system going to linp-in mode. Learn how it works and how to test this incredible component. (note: We allow all schools and training institutions to use our software free of charge, so long as it is not sold to others.

Knock Sensor Quick-Fix
SOFTWARE CATALOG: http://www.autodiagnosticsandpublishing.com/Software_Catalog.html Knock Sensor Quick-Fix The knock sensor is used by the ECM to fine tune ignition timing. A faulty knock sensor will cause a faulty code to set, and may also cause ignition timing to be skewed. Lack of power may also be another symptom. These are the knock sensor facts. 1) The knock sensor is a type of microphone, screwed to the engine block or manifold. 2) It is a piezo electric or crystal component. 3) Knock sensors produce their own electricity. 4) A knock sensor produces alternating or AC current. 5) The sensor is tuned to between 6 to 9 thousand Hertz, which is the pinging frequency, so as not to confuse the ECM. 6) There are two types of knock sensors, the older wide band, and the newer resonant or tuned knock sensor. 7) You test these two types of sensors differently. 8) To test the wide band knock sensor, with engine and key off, probe with a volt meter set to AC, between battery ground and the knock sensor signal wire. Then, light tap near the knock sensor using an extension or back of the ratchet wrench. 9) The resonant newer style knock sensor will not react to engine tap. These sensors are tuned only to an engine ping. 10) To test these sensors, connect the volt meter as before, start the engine, then remove the fuel pump relay or fuse. As the vehicle is starved for fuel, pre-load the engine a bit by putting the car in gear, foot on brake, and accelerate a bit. The fuel starved engine will ping. On both tests you should see an AC voltage outputted. That concludes the knock sensor Quick-Fix.

P0325 Knock Sensor Diagnosis - EricTheCarGuy
Visit me at: http://www.ericthecarguy.com/ Wells website http://www.wellsve.com/ Wells YouTube (great videos I recommend you subscribe) http://www.youtube.com/user/markjhicks As you can see by the title this video covers the diagnosis and repair of a P0325 on my 1997 Subaru Legacy L model with 2.2L engine backed by an auto trans. I did have some trouble with the 'factory' diagnostic procedure but thankfully my friend Mark at Wells Electronics had a test that involved a voltage drop across the sensor that worked perfectly. I hope this video illustrates the import ants of understanding a circuit that you're diagnosing as opposed to just throwing parts at something, with a little time and effort you can do a proper diagnosis. --- Click below and Stay Dirty Visit me at EricTheCarGuy.com http://ericthecarguy.com/ Visit EricTheCarGuy Forum http://www.ericthecarguy.com/forum/default.aspx Visit my Facebook Page: http://www.facebook.com/EricTheCarGuy --- Stay dirty ETCG Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.  EricTheCarGuy assumes no liability for property damage or injury incurred as a result of any of the information contained in this video. EricTheCarGuy recommends safe practices when working with power tools, automotive lifts, lifting tools, jack stands, electrical equipment, blunt instruments, chemicals, lubricants, or any other tools or equipment seen or implied in this video.  Due to factors beyond the control of EricTheCarGuy, no information contained in this video shall create any express or implied warranty or guarantee of any particular result.  Any injury, damage or loss that may result from improper use of these tools, equipment, or the information contained in this video is the sole responsibility of the user and not EricTheCarGuy.

Re: P0325 Knock Sensor Diagnosis - EricTheCarGuy
Visit me at: http://www.ericthecarguy.com/ Some great points were brought up in the comments of the original video including that I was not using my meter to check the resistance of the circuit correctly when I did the resistance check on the knock sensor therefore I HAD to make this video covering that mistake along with video of doing the test properly and how to set the multimeter. I also take the opportunity to show the different settings on a DVOM and how to use them so I think this video stands on it's own just for that purpose.

How To Clean a Mass Airflow Sensor (In-depth, detailed version)
How to clean a Mass Airflow Sensor, MAF, Mass Airflow Sensor cleaning can increase fuel economy, stop hesitation and stalling, and shut off your check engine light. This is a simple procedure and in this video I go in-depth about cleaning the sensor and I take readings from an OBDII scanner to show before and after cleaning the sensor. A mass airflow sensor gets dirty because of oiled filters such as a KNN air filter, air filters that are not replaced often enough, and dusty roads (salt, sand, pollen, etc). Symptoms of a dirty MAF sensor are hesitation, poor idle, bad fuel economy, and stalling. You can also get a check engine light with codes P0100, P0102, P0103, P0104, and P0105. **If the video was helpful, please give it a "thumbs up" and consider subscribing. Leave any questions or comments below and I will answer them as well.** Average Fuel Economy for the month before I cleaned the sensor: 17.5mpg 1 fill-up later: 18.97mpg 2 fill-ups later: 20.86mpg 3 fill-ups later: 19.10mpg 4 fill-ups later: 20.1mpg 5 fill-ups later: 19.13mpg Cleaning a MAF to stop Hesitation and Stalling COMING SOON How to Fix a Car that Idles Poorly https://www.youtube.com/watch?v=vFhoNykgQtc Make your own Penetrating Fluid https://www.youtube.com/watch?v=2WuVBFTzoKc Follow me on Facebook: https://www.facebook.com/chrisfix8 Follow me on Twitter: https://twitter.com/ChrisFixed Subscribe: http://www.youtube.com/subscription_center?add_user=paintballoo7 Disclaimer: Due to factors beyond the control of ChrisFix, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.

DIY: Subaru Knock Sensor Testing
Video tutorial on how to diagnose a faulty knock sensor on a Subaru. A faulty knock sensor will typically cause poor fuel mileage, decrease in power, flat spots in the throttle, throttle hesitation, and hard starting. This particular video was done on a 1999 Subaru Forester with a 2.5L 4 cylinder. How to remove/replace the knock sensor: http://www.youtube.com/watch?v=gIPGa5x1kQE Procedure: -first you want to cheap for any breaks or corroded wiring/plug connections -you can do a continuity test to determine if there is a fault wire within the circuit (tutorial here http://www.youtube.com/watch?v=pDzRsOpne_Q) -check for a clean ground connection between the sensor on the engine block -check for any cracks in the casing of the sensor which would make it susceptible to moisture -disconnection the wire, using an multimeter set to the voltage setting, testing the harness on the ecu/vehicle side, enure there is an approximate 5V reading when the key is in the on position -removing the sensor, using a multimeter set to the ohm setting, testing the sensor and it should have a reading of 400,000ohm (400k ohm) or more which will determine that the sensor is still good -ensure that the sensor is install in the proper position which is 60 degrees in accordance with the rear of the engine Thank you to all those who watch my videos and support my content.
