What causes the p0138 code on a Jeep Liberty?
Here are the most common issues that cause the P0138 code in the Jeep Liberty. 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 does the p0171 code on a jeep mean?
P0171 JEEP Tech Notes If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persistss the front oxygen (O2) sensor may need to be replaced.
What is the oxygen sensor code on a Jeep Liberty?
Jeep Liberty P0138: Oxygen Sensor High Voltage (Bank 1 -Sensor 2) P0138 is a common OBDII code that occurs in many vehicles, including theJeep Liberty. The code is triggered when: There are also some less likely problems that can cause P0138.
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 fault code p0172 and p0175 mean?
P0172/P0175 Diagnostic Theory for Shops and Technicians. When a vehicle has the fault code P0172 and or P0175, it means that computer can no longer automatically adjust the mixture between air and fuel. Code P0172 applies to Bank 1 and P0175 applies to Bank 2.
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 does the code p0138 on a boxer engine mean?
Code P0138 is set when the downstream sensor sends too high of a voltage signal for an extended period of time. The bank one portion of the code indicates that the issue is on the side of the engine that houses the number one cylinder (only applies to engines with a ‘V’ or boxer configuration).
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 OBDII code on a Jeep Wrangler?
P0138 is a common OBDII code that occurs in many vehicles, including the Jeep Wrangler. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more
