2000 Honda Passport what do they use for a check engine light?
A 2000 Honda Passport uses an OBD II (On-Board Diagnostics II) system for its check engine light. This system uses a standardized diagnostic connector and communication protocol to store trouble codes related to various engine and emission systems. A scan tool (either a generic OBD II reader or a Honda-specific one) can be plugged into this connector to read the stored codes, which will help pinpoint the reason for the light illuminating.
