OBD-II Trouble Code Technical Description
ISO/SAE Reserved (no valid description)
What is the meaning of this code?
This code is rarely seen because it is not a valid diagnostic trouble code, so it is not displayed by many code reading devices.
Although it starts with P00 like other P00xx codes, it is not a generic powertrain code under the category “Fuel & Air Metering and Auxiliary Emission Controls Read”. It is invalid.
It is important to note that some code readers may display a P0000 code with descriptions such as “No Self Diagnostic Failure Indicated”, “No Diagnostic Trouble Codes Found”, or “Unknown”.
Symptoms
The P0000 code does not cause any symptoms. However, you may experience symptoms related to other trouble codes. The Malfunction Indicator Lamp may or may not be illuminated.

Diagnostic and Repair Procedures
If you only have this trouble code and no symptoms, you can continue driving the vehicle without worrying about it. You may choose to clear the code and check again later to see if it returns. If it does, consider using a more advanced scan tool next time.
If you have symptoms of a problem and there are other trouble codes along with P0000, focus on repairing the other trouble codes first.
If there are no other codes and you have symptoms of a problem, use a different, more advanced code scanner to read the trouble codes. Make sure to check with the manufacturer of the tool to see if your vehicle is supported.
