Web if the o2 sensor voltage is sticking rich or lean: However once i pushed the gas a bit you see it changing to 0.1 to 0.3v at around 5000rpm. Web normal o2 sensor voltage at idle. This means when the engine is a the normal operating temperature it's closed and when its cold warming up it open. As the mixture becomes rich, the voltage will increase (up to 0.9 volts). Web start the engine and let it idle for about two minutes while watching the digital reading on the voltmeter. The o2 sensor measures the oxygen content of the exhaust. Web the o2 sensors are always located in the exhaust and monitor how much unburned oxygen is present in the exhaust. A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts.

Web if your upstream o2 sensor continuously gives out a voltage that is consistently about 450 mv, this may mean that your oxygen sensor is not responding to the fuel mixture. This means when the engine is a the normal operating temperature it's closed and when its cold warming up it open. Web start the engine and let it idle for about two minutes while watching the digital reading on the voltmeter. Web when the o2 sensor’s voltage is too high, it means that the sensor is detecting too little oxygen in the exhaust system.
