Expert Solution
To determine

The technician with correct approach while discussing a proper way to test catalytic converter.

### Explanation of Solution

Given:

Technician A says that a pressure gauge can be inserted into the oxygen sensor bore and the backpressure caused by the converter measured.

Technicians B says that restrictions in the converter can be checked with a vacuum gauge while the engine is being quickly accelerated.

Restricted exhaust flow is caused due to overheating of catalytic converter. To measure the exhaust system back pressure, a pressure gauge is inserted into the oxygen sensor’s bore in the exhaust...
