VIDEO: Is Your Engine Knock Sensor Working Properly?

The greater the vibration or shock, the higher the voltage and frequency. This video is sponsored by NGK and NTK.

The knock sensor is a piezoelectric accelerometer that acts as a microphone on the engine. It converts vibrations into alternating current (AC) signal. When the crystal inside the sensor is vibrated, it produces an AC voltage.

The greater the vibration or shock, the higher the voltage and frequency. In this video we discuss how a knock sensor can fail, testing and diagnostics.

Learn How To Safely Lift HEVs and BEVs

If you can’t lift a vehicle without damage, you will not be able to unlock this service opportunity in this growing segment.

Most HEV and EV vehicle repairs are not those done to battery packs or electric motors. Instead, the most significant repair opportunities are tires, brakes, and suspension. And if you can’t lift a vehicle without damage, you will not be able to unlock this service opportunity in this growing segment. The stakes are higher for EVs and hybrids because if a lift arm or adapter is not correctly placed, it could damage an expensive battery pack mounted under the vehicle. Some of these battery packs can cost five figures to replace. Also, there is a fire hazard. If a battery pack is impacted or punctured, never guess where or how to pick up a vehicle. A vehicle’s owner’s manual or service manual often will provide guidance on where to find and how to access the appropriate jacking and lifting points. Some EVs and HVS have specific lift points stamped into the unibody.
