O2 Sensor Downstream Voltage at Ana Robles blog

O2 Sensor Downstream Voltage. An unnormal downstream voltage chart could be a. If the catalytic converter is working properly, the downstream o2 sensor should detect very little oxygen in the exhaust gases. the downstream o2 sensor measures the oxygen content of the exhaust gases after they have passed through the catalytic converter. These readings can help diagnose fuel system problems and emission issues. The engine’s computer uses this voltage to determine if the fuel mixture is rich (less oxygen) or lean (more oxygen) and adjusts accordingly. if the o2 sensors, catalytic converter, or fuel injectors are damaged the downstream o2 sensor voltage could be higher or lower. A higher voltage means there is too much fuel in the mixture. A lower voltage means there is too much oxygen in the mixture. an o2 sensor works by generating a voltage when it detects oxygen in the exhaust. the upstream o2 wideband sensor value (or rather its interpretation by the ecu) oscillates around 14.7. a properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. The amount of voltage produced varies with the amount of oxygen present; what should you do if the downstream o2 sensor is bad?
