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.





Variable CAM Timing
Variable CAM Timing Get the book here: https://www.createspace.com/4321251 Variable CAM timing is a concept that entails changing the camshaft timing, as needed, depending on engine LOAD demands. This technology was impossible just a few years ago, due to the state of the art electronics needed. The latest Variable CAM Timing (VCT) systems are infinitely variable, meaning they have no specified settings. CAM timing can be changed or varied instantaneously across the whole range (ie. Plus or Minus 30 degrees from normal). By varying the CAM timing, the ECM can regulate the power curve to meet its own needs. On any gasoline engine, each RPM setting has an optimum CAM timing setting, depending on load. Up until a few years ago engines were set whatever the CAM lobes were machined at. With modern VCT, this relationship can be varied, also varying the engine's power curve. Most modern VCT systems do not control valve lift, but do great by simply changing open and close timing points during engine operation. See how it works here, with this superbly animated training video on automotive technology and variable cam timing (VCT). *************************************************************************** *********** Amazon Printed-Books & Kindle: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dstripbooks&fiel d-keywords=mandy+concepcion Google Play Android APPs: https://play.google.com/store/search?q=mandy+concepcion&c=apps Amazon Video DVDs: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dmovies-tv&field -keywords=mandy+concepcion Barnes & Noble Nook: http://www.barnesandnoble.com/s/mandy-concepcion?keyword=mandy+concepcion&s tore=allproducts Apple iTunes iPad: http://itunes.apple.com/us/artist/mandy-concepcion/id449573393?mt=11

The CAM and CRK sensors are types of speed sensors. There are variations of each and these varieties will dictate the way you test the sensor. Explained here are specific electrical values, such as voltage signals and how the sensor is connected to the ECM itself. This is vital information since most of the diagnostic time is spent in analyzing the wiring diagrams for the component in question. Presented here using the latest CG and graphic animation technology. Part of our wiring diagram set of videos shown here on this channel.
