O2 Sensor Voltage Stays High at Mary Nealy blog

O2 Sensor Voltage Stays High. That sensor’s location can vary from vehicle to vehicle. Its voltage is supposed to stay around 0.5 volts and not alternate too low or too high. Inspect wiring for damage or loose connections. Diagnostic trouble code (dtc) p0138 stands for o2 sensor circuit high voltage (bank 1, sensor 2). A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. The code will set when your car’s primary computer—also called the powertrain control module (pcm)—detects that, for a given period of time, the voltage signal from the rear o2 sensor is too high. This code indicates excessive voltage from bank 2, sensor 1, potentially affecting engine performance. Experiencing a p0152 trouble code due to high voltage in your o2 sensor? When the o2 sensor’s voltage is too high, it means that the sensor is detecting too little oxygen in the exhaust system. If you have a dtc of p0138, it’s indicating a problem with high voltage in an oxygen sensor monitors the oxygen levels in the exhaust gases for bank 1, sensor 2. Some common causes of a high o2 sensor voltage reading include fuel injectors that are leaking or stuck open, a faulty fuel pressure regulator, a malfunctioning mass airflow sensor, exhaust leaks before the sensor, a clogged air filter, or problems with the engine’s fuel management system. Check for voltage fluctuations or sensor malfunctions. Here’s what the downstream o2 sensor signals.
