Sensors serve the purpose of recording physical variables in their vicinity and converting them into electrical signals so that they can be processed by control units. This training system explains the function and diagnostic procedures involved in diagnosing key engine management sensor systems in both theory and practice.

Training contents:

• Physical principles: Induction, Hall effect, piezo-effect
• Purpose of sensors for engine control
• Inductive and Hall-type speed sensors and how they work
• Measurement of throttle valve position: throttle valve switches and potentiometers
• Mass air flow measurement using hot-filament and hot-wire sensors
• Measurement of pressure in the intake manifold
• Detection of shock waves using a knock sensor
• Temperature measurement using NTC and PTC sensors
• Troubleshooting (8 simulated faults activated via relays)
• Course duration:  10 h approx. (including about 2 hours for troubleshooting)
