Downstream Oxygen Sensor High Voltage at William Farr blog

Downstream Oxygen Sensor High Voltage. 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. Code p0138 is set when the downstream sensor sends too high of a voltage signal for an extended period of time. When the o2 sensor’s voltage is too high, it means that the sensor is detecting too little oxygen in the exhaust system. 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. A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. The p0138 dtc is a generic trouble code that says the oxygen sensor circuit (bank 1, sensor 2) is exhibiting higher voltage than normal. The p0138 code means the engine control module (ecm) has detected a high voltage signal (over 999 mv) from the downstream. Downstream may have some minor.
