Do you need a machine to get the obd code for 1990 Nissan Stanza?

Yes, you will typically need an OBD-I scanner or an appropriate diagnostic tool to retrieve the OBD code from a 1990 Nissan Stanza, as this vehicle uses the OBD-I system. Unlike later models that utilize OBD-II, OBD-I systems often require specific equipment or a manual method to read codes. You can also check for diagnostic trouble codes by using a paperclip or jumper wire to connect certain pins in the diagnostic connector, which may trigger a flashing check engine light.
