If you have a multimeter, be sure you warm the car prior to conducting tests. The voltage on your digital multimeter can rapidly fluctuate between 0.01 volt and 1.01 volt when it is warm. The oxygen sensor vauxhall diagnostic near me could be malfunctioning if the readings don't stay within this range.
