If a technician notes a missing hot air tube and a plugged EGR hose, which entries should be recorded for TAC and EGR statuses?

Explanation:
The test focuses on whether observed hardware matches the expected OEM setup for TAC and EGR. A missing hot air tube means the TAC component is not present, so TAC should be recorded as missing. A plugged EGR hose indicates the EGR path has been altered from its normal condition, so it’s recorded as modified rather than normal. In this scenario, TAC is missing and the EGR path is modified, which is why the correct recording is TAC missing and EGR modified.
