To detect if the oxygen sensor is normal, apart from testing circuits and sensors with digital multimeter, V.AGl551 diagnosis instrument can do some further tests, too.To do the detection, the temperature of engine coolant should be above 80℃, after the detection, idling speed should be normal, ventilation without leakage, the power supply of heating components inside oxygen sensor normal, resistance all right.(1)connect the VAG1551 diagnosis instrument, choose the functions codes of 01, enter the address of engine electric spray controller. When the screen shows fast data transportation , choose the assistance function of XX'.
