The electric components in your vehicle require a constant flow of electricity to work properly. That means they must get the right voltage at all times. The same is true for the O2 sensor (oxygen sensor) that measures the exhaust gases to improve efficiency. Our crew at our Performance Shop in Charleston are well-versed in such matters and can treat such issues in a heartbeat. So, don’t hesitate to book an appointment at the earliest. But before you do that, let’s discuss the error codes P0131, P0132, and its derivatives that you see with low or high voltage in your Subaru.
What Does the Code Mean? | Performance Shop Charleston
The error code P0131 stands for Front O2 sensor low voltage. In simple words, this means that the particular sensor is receiving insufficient voltage, which can result in performance issues. Such an issue can arise if the O2 sensor is near failure or has malfunctioned completely. Moreover, it can also mean that there is a connection issue between the battery and the sensor. So that must also be checked before resorting to more drastic measures. Finally, a wiring issue for the sensor can cause the same problem. So, it’s best to get it all looked at by professionals like the ones at the Performance Shop Charleston.
Other Similar Codes?
The code P0131 isn’t the only one representing voltage issues. The error code P0132 does the same, except it pops up when there is an issue with high voltage. Therefore, it is the exact opposite of the other code.
The codes P0137 and P0138 also point to the same voltage issues, but this time for the rear O2 sensor.
Voltage issues are a result of a problem in the battery. So, before you do anything, try checking the battery connections and ensuring it is in a healthy state. If you find some problem there, there is no need to look further. Simply clearing the code through the scanner after making repairs will do the trick. However, if the problem persists and the check engine light is still on, then you can move on to your second option. The other choice you have is cleaning the O2 sensor using ethanol. This usually does the job, but it’s not magic, which means you won’t see the results that you want if the sensor is faulty. So, your last option is to check the wiring and replace the old sensors with a set of new ones. It’s cheap work and necessary if you want your car to be efficient.
