Can I diagnose P2002 with a basic code reader?

P2002 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.

Is it safe to drive with P2002?

It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
