A multimeter can be used to test the voltage if you're not sure. The multimeter will display the readings from both the downstream and upstream oxygen sensors. Before you test your multimeter, warm your vehicle. The voltage on your digital multimeter can rapidly fluctuate between 0.01 volt and 1.01 volts when it is warm. If the readings are not in this range, then the oxygen sensor could be malfunctioning.

Diagnostics cost
