An illustrated reference guide to all onboard vehicle sensors. Each type of sensor is fully covered including how it works, typical applications, outputs, diagnosis, testing and sample waveforms. All onboard sensors for all vehicles are covered including:

• Oxygen sensors
• Coolant sensors
• MAP sensors
• BARO sensors
• Throttle Position Sensors (TPS)
• Mass Airflow sensors (MAF)
• Vane Airflow sensors (VAF)
• Karmen Vortex Airflow sensors
• Knock sensors
• Air Temperature sensors
• EGR valve position sensors
• Crankshaft position sensors
• Camshaft position sensors
• Vehicle Speed Sensors (VSS)
• Wheel Speed Sensors (WSS) on ABS systems
• Steering angle sensors
• G-Force sensors
• Airbag crash sensors

There are also special "background" sections in Sensor Guide that review the basics of:

• Computerized Engine Controls
• DIS ignition systems
• Using a digital oscilloscope (DSO) to read waveforms
• Fuel injection
• Basic electrical circuits
• Basic electronic theory
• OBDII (with list of all engine-related OBDII codes)

Sensor Guide is a comprehensive reference program that every technician, instructor and student should have for servicing today's high tech engine management systems. Use in the shop, in the classroom or as a study guide for taking the ASE Engine Performance Test or the LT1 Advanced Engine Performance Test.
