What causes the p0138 code on a Nissan Pathfinder?
Here are the most common issues that cause the P0138 code in the Nissan Pathfinder. They are presented in order (somewhat) of most to least likely to cause the problem. Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0138 is triggering your service engine soon light.
What is the OBDII code on a Nissan Pathfinder?
P0138 is a common OBDII code that occurs in many vehicles, including the Nissan Pathfinder. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more There are also some less likely problems that can cause P0138. We’ll go over those below.
What does the code p0138 mean on the O2 sensor?
What the P0138 code means. P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream.
What is the OBD code for bank 1 sensor 2?
P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream.

What does the p0138 code on the ECM mean?
The P0138 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively high for an extended period of time.
What does p0138 mean in a catalytic converter?
O2 Sensor Circuit High Voltage (Bank 1, Sensor 2) What Does P0138 Mean? Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter. It measures the amount of air and fuel coming out of the catalytic converter to ensure the catalytic converter is functioning properly.
What does the p0139 code on the O2 sensor mean?
Although the signal from the front sensor (sensor 1) changes far more rapidly than that of the rear (sensor 2), both change over time. When the rear oxygen sensor mounted on engine bank 1 doesn’t transition between voltage states fast enough, the engine computer logs a P0139 code. What Does the P0139 Code Mean?
O2 Sensor Circuit High Voltage (Bank 1, Sensor 2) What Does P0138 Mean? Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter. It measures the amount of air and fuel coming out of the catalytic converter to ensure the catalytic converter is functioning properly.
What is the OBDII code on a pathfinder?
P0138 is a common OBDII code that occurs in many vehicles, including theNissan Pathfinder. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more.
