How to test 5 or 6 wire Wideband O2 sensor with multimeter, OBD scan tool.O2 sensor readings. Hindi

On running Engine, testing of 5 and 6 wire Wideband o2 sensor with Multimeter and OBD scan tool is demonstrated with the help of Oscilloscope/pecoscope to analyze the the signal waveform for the diagnosis of Lambda sensor and AFR sensor.This procedure can be used for checking the out put of 5wire and 6wire wideband o2 sensor that is also called Lambda sensor, UEGO sensor ,AFR and air fuel ratio sensor. OBD scan tool is used here to monitor and analyze Nernst cell output, pump cell current and voltage with simulating the change in ratio of the air fuel mixture . This video is very useful for EFI technicians those are learning the skill to diagnose faults of automobile engines using electronic fuel injection technique for combustion control. Wideband o2 sensor heater circuit testing and its supply voltage is also checked and monitored to provide the set values for the readings of healthy sensor to be compared with . This video contains the full procedure applicable to check the voltage on every pin/wire of the wideband lambda sensor working on running engine. Signal output and voltage of pumping cell, Nernst cell, elevated or virtual ground , as well as trimming current and heater supply voltage measurement is demonstrated with the help of Lab tools like Multimeter, OBD scan tool and oscilloscope to present reference data about the AFR sensor in very easy and practical way. Lambda sensor test has been performed in this video. Check and test of o2 sensor is explained as well as air fuel ratio sensor test is taught in simple way. Enjoy the full detail about oxygen sensor testing procedure and understand the wideband oxygen sensor testing and readings. #WidebandO2SensorTestingWithMultimeter #O2SensorTest #LambdaSensorTest #OxygenSensorTesting
