To clear a historic fault code, you will need to use a diagnostic tool. Once you have the diagnostic tool, you will need to connect it to the vehicle’s on-board diagnostics port. After the connection is made, you will need to follow the prompts on the diagnostic tool to clear the code.
- Look up the specific fault code in an online or printed resource
- Identify the steps necessary to clear the fault code, which may include disconnecting the battery, resetting a fuse, or reprogramming a module
- Follow the steps necessary to clear the fault code
- Check that the fault code has been cleared by starting the vehicle and observing the check engine light
- If the light is still on, consult your resource to troubleshoot further

How to Clear Permanent Obd2 Codes
When it comes to clearing permanent OBD2 codes, there are a few different ways that you can go about doing so. In this blog post, we’ll take a look at a few of the most popular methods for clearing these codes so that you can get your vehicle back up and running as quickly as possible.
One of the most popular methods for clearing permanent OBD2 codes is to use an OBD2 code reader/scanner tool.
These tools are designed to work with your vehicle’s on-board diagnostic system to help you identify and clear any codes that may be present. Many of these tools also have the ability to reset your vehicle’s check engine light, which can be helpful if the light is coming on frequently or if it’s been on for an extended period of time.
Another popular method for clearing permanent OBD2 codes is to disconnect your battery for a brief period of time.
This will cause your vehicle’s computer to reset itself, which should clear any stored codes. However, it’s important to note that this method should only be used as a last resort, as it can potentially damage other electronic components in your vehicle if not done correctly. If you’re unsure about how to properly disconnect your battery, we recommend consulting with a professional mechanic before proceeding.
Finally, some mechanics may also recommend using an electrical circuit tester or multimeter to test various points in your vehicle’s electrical system until the source of the problem is found and corrected. While this method can be effective, it’s often more time-consuming than using an OBD2 code reader/scanner tool and can sometimes result in damaging other parts of your car if not done carefully. We recommend having a professional mechanic handle this type of diagnosis and repair whenever possible.

How Do I Clear a Permanent Fault Code?
If your car has a permanent fault code, it means that there is a problem with the car’s emission control system. The code will stay in the car’s computer, and the check engine light will stay on until the problem is fixed.
There are a few things you can do to try and clear a permanent fault code:
– Check all of your emissions control system components to make sure they are functioning properly. This includes the oxygen sensor, catalytic converter, and EVAP system.
– If you have recently replaced any of these components, make sure they are properly installed and connected.
– Make sure there are no leaks in your emissions control system. A leak can cause the system to not work properly and throw a permanent fault code.
How Long Does It Take for Permanent Dtc Codes to Erase?
Permanent DTC codes are those that do not go away on their own and must be erased by a mechanic. The time it takes to erase a permanent DTC code varies, but it is usually quick and easy to do.
Do Fault Codes Clear Themselves?
No, fault codes do not clear themselves. Once a code is stored in the vehicle’s computer, it will remain there until it is cleared by a mechanic or technician.
Can You Pass Emissions With a Permanent Code?
It’s a common question with a not so simple answer. In short, the answer is maybe. Depending on the state in which you reside, permanent engine codes may or may not prevent your vehicle from passing an emissions test.
Some states, like California, have what’s called a “rolling emission” standard. This means that your vehicle must be less than a certain number of years old to be required to take and pass an emissions test. For example, in California, any vehicles model year 1975 or newer must pass an emissions test before being registered with the DMV.
Other states have what’s called an “inspection and maintenance” (I/M) program which requires all vehicles within a certain age range to take and pass an emissions test every one or two years. However, if your vehicle has been diagnosed with a permanent engine code, it may be exempt from I/M testing requirements.
So while the answer to whether or not you can pass emissions with a permanent code is technically yes, there are several factors at play that will determine if your vehicle will actually need to take an emissions test and if it will ultimately pass.
Conclusion
If your “Check Engine” light is on, it means your car’s onboard computer has logged a fault code. These codes are associated with different problems, and can be cleared by accessing the computer and clearing the codes. This process is relatively simple and can be done at home with a few tools.
