P06B8 Code: Internal Control Module Non-Volatile Random Access Memory (NVRAM) Error

On-board diagnostic (OBD) codes help mechanics and drivers pinpoint problems within different vehicle systems. To successfully troubleshoot these issues, it’s important to know what these codes mean.

Code P06B8 is one of many trouble codes that can be logged and retrieved from the OBD system. Here is some helpful information that can help you understand what getting this code can mean for your vehicle.

What Does the P06B8 Code Mean?

Diagnostic trouble code (DTC) P06B8 stands for “Internal Control Module Non-Volatile Random Access Memory (NVRAM) Error.” This code indicates there is a problem with the NVRAM in the powertrain control module (PCM). The NVRAM is the portion of the module’s memory that retains stored data even without applied power.

Internal control module monitoring processors make sure that the different controller self-tests are functional and that the overall internal control module is operational. Code P06B8 can indicate that the PCM cannot correctly store permanent DTCs in its memory.

If the PCM detects a problem with the NVRAM processor, error code P06B8 will be logged.

Depending on the severity of the problem, related error codes might also be stored with this DTC. Code P06B8 is similar to error code P16F9.

Note: The definition of code P06B8 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
