What OBD parameters does the software support?

First of all, to show some parameter or sensor value reading from your car, your car must have support for it.

Unfortunately, we can’t tell what parameters and sensors each car model supports. To find out that yourself, you can use the free version of the software. The free version will list all supported items — it only hides/masks some of the readings.

So, to view a specific parameter value, your car must support the functionality. Moreover, the parameter must be defined in the OBD2 standard, and our software needs to have support for it.

OBD Auto Doctor supports the following standard OBD-II parameters (PIDs) defined in SAE J1979-DA MAR2022. The actual list of available parameters is vehicle-specific. Only the parameters supported by the car will be shown in the software.
