Electrical verification with PICO oscilloscope of a broadband lambda probe in a diesel. -Explanation of how to connect the oscilloscope to the lambda probe, Identification of the probe connection cables. An explanation of which voltage values must be measured with channels A, B and C with respect to ground is given, pumping voltage, reference voltage and Nerst voltage are measured. -Measurement of the reference voltage, analysis of the voltage values measured with respect to ground. -Measurement of the pumping voltage with respect to ground. Analysis and explanation of the voltage values measured with respect to ground (engine idling). -Measurement of the Nerst voltage, analysis and explanation of the measured values. -Behaviour of the pumping voltage to variations in load and quantity of fuel injected. Explanation of the application of the parameter measured by the lambda probe in engine management. -Behaviour of the Nerst voltage to variations in load. -Voltage oscillogram of the potential difference between the pump voltage terminal referred to the reference voltage terminal. Analysis of the voltage values obtained under different operating conditions. -Electrical verification of the heating of the broadband lambda probe. Explanation of the need for this heating and how it is controlled. Connection of the oscilloscope with three channels, positive power supply, negative control and heating current. Explanation and analysis of the voltage and current values obtained. Oscilloscope Tutorial 09 • 📚COMPLETE EXPLANATION of a lambda probe... We carry out the tests with a PICO PQ178 oscilloscope.
