What does P0158 mean on the oxygen sensor?
Therefore, the downstream oxygen sensor (sensor 2) should produce a steady voltage of approximately 0.45 volts. When trouble code P0158 is set, this indicates that there is a high voltage (steadily above .9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on bank 2 of the engine.
Why is my oxygen sensor on my Jeep not working?
Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0157 is triggering your service engine soon light. Although it is a temptation to replace it right away, it wouldn’t hurt to check out the wiring harness around it beforehand. See directly below. They are relatively affordable at Autozone or Amazon.
What does Bank 2 O2 sensor code mean?
Although generic, the specific repair steps may vary depending on make/model. This code refers to a fault in the post-catalyst o2 sensor on Bank 2. First, a basic run-down of the catalyst: The Catalytic Converter is used to help control tailpipe emissions, to “clean up” the exhaust, if you will.
What does p0157 mean on a Jeep Wrangler?
P0157 is a common OBDII code that occurs in the Jeep Wrangler, it’s a general code (this means that it has the same meaning for any vehicle). This code typically indicates that there is an issue with the wiring or harness going to the sensor, or the sensor itself is bad. There are other things that cause P0157 to populate. We’ll cover those below.
What causes the P0158 code on a Jeep Wrangler?
Here are the most common issues that cause the P0158 code in the Jeep Wrangler. 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 P0158 is triggering your service engine soon light.
What causes a P0158 code on an O2 sensor?
Potential causes of an P0158 code include: Bad o2 sensor (Bank 2 Sensor 2) Wiring in contact with exhaust components Engine running rich (If other codes are present) Holes in exhaust causing PCM to over-rich engine resulting in an abnormally high Bank 2, sensor 2 reading Short to voltage on signal circuit Bad PCM

What does trouble code P0158 mean on a Honda Accord?
All our repairs are backed by our 12-month / 12,000-mile warranty. The P0158 trouble code appears when the sensor has remained at a high voltage for too long. This oxygen sensor is located behind the catalytic converter.
What are the symptoms of a P0158 DTC?
Symptoms of a P0158 DTC may include: MIL (Malfunction Indicator Lamp) on Engine loses power and misses intermittently May exhibit loss of fuel efficiency Potential causes of an P0158 code include: Wiring in contact with exhaust components Engine running rich (If other codes are present)
Is it okay to drive a car with P0158?
It is okay to drive a vehicle with P0158 for a short period of time, but driving with this code for an extended period of time can damage the catalytic converter (s). Replacing the O2 sensor without checking to see if the vehicle is running rich due to another problem.

What does the DTC code p0138 stand for?
Diagnostic trouble code (DTC) P0138 stands for O2 Sensor Circuit High Voltage (Bank 1, Sensor 2). 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.
Symptoms of a P0158 DTC may include: MIL (Malfunction Indicator Lamp) on Engine loses power and misses intermittently May exhibit loss of fuel efficiency Potential causes of an P0158 code include: Wiring in contact with exhaust components Engine running rich (If other codes are present)
What is the error code for the O2 sensor?
Error Code P0158 is defined as O2 Sensor Circuit High Voltage Bank 2 Sensor 2. This refers to a trouble in the Bank 2 Sensor 2 of the O2 (oxygen) sensor, which is located near the backside of the exhaust, behind the catalytic converter.
What does error code P0158 mean on a Honda Accord?
Error Code P0158 is quite a serious trouble code that needs attention ASAP, as it causes drivability issues, such as stalling which can be dangerous when driving. When conducting a repair for this error code, the O2 sensor set and propane tank are needed to remove the O2 sensor if it is difficult to reach or has ceased in the exhaust.
Error Code P0158 is defined as O2 Sensor Circuit High Voltage Bank 2 Sensor 2. This refers to a trouble in the Bank 2 Sensor 2 of the O2 (oxygen) sensor, which is located near the backside of the exhaust, behind the catalytic converter.
What does the p0138 code on a car mean?
Code P0138 means that your powertrain control module (PCM) has detected that the voltage signal from the rear O2 sensor is too high. What is an Oxygen Sensor? All modern cars have at least two oxygen sensors.
