Wideband O2 Sensor Voltage at Robert Goldsmith blog

Wideband O2 Sensor Voltage. The difference between the oxygen in the sensor and the oxygen in the exhaust is what determines how much voltage is produced. Here's everything you need to know about wideband o2 sensors: The basic operating principle of a wideband o2 sensor involves a zirconia or titania element that generates a voltage signal based on the oxygen content in the exhaust gas. When the o2 sensor signal stuck at 0.45v. Then how do you know if the upstream oxygen sensor is bad? One cycle is made when the o2 sensor signal crosses the 0.45v point approximately 3 times (3 cross counts). A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. Measuring the activity of the broadband oxygen sensor using the volt drop method accompanied with ohm's law removes the need for expensive milliamps clamp to measure. That voltage is then sent to the ecu to determine what your current air/fuel ratio is and what needs to be changed to reach stoich. Wideband oxygen sensors measure the oxygen content in the exhaust gas of an engine. The voltage signal should also go higher than 0.75v and lower than 0.25v.
