What Voltage Should An O2 Sensor Read At Idle at Krystal Russell blog

What Voltage Should An O2 Sensor Read At Idle. The downstream oxygen sensor should typically generate a constant voltage of roughly 450 mv. It should read between 0v and 1v typically. The upstream o2 sensor electric potential can vary from 0.1 to 0.9 volts, where a reading of 0.1 volts indicates a lean mixture and 0.9 v. Sensor 1 is supposed to fluctuate 1 cycle a second between 0.1v and 0.9v. A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. O2 sensor will usually generate.9 volts when the fuel mixture is rich and there is little unburned oxygen in the exhaust. The voltage signal should also go higher than 0.75v. If it's pegged constantly at 0 or 1v it could be bad. A low voltage (typically around 0.1 to 0.3 volts) indicates a lean. O2 sensor voltage readings can be interpreted as follows: What should an o2 sensor read at idle? And if it’s lower, either the sensor circuit is malfunctioning, or there is too.
