Yes.
Can be used for both OBD1 and OBD2 spec.
Yours is OBD1 and DBW spec.
If not sure about the actual code, please take a video from IGSW in P0 Off position and try to include all readings including the volt gauge.

Even without triggering the warning light, it's worth reading the error code at least once a year.

Some of the error codes require two consecutive drive cycles or two detection within the same drive cycle before triggering the warning light.
Therefore, even without any warning lights, still, you may have error code stored on certain controllers.
