Textbook Problem

While discussing the proper way to test a catalytic converter: Technician A says that a pressure gauge can be inserted into the oxygen sensor bore and the backpressure caused by the converter measured. Technician B says that restrictions in the converter can be checked with a vacuum gauge while the engine is being quickly accelerated. Who is correct?

a. Technician A only

b. Technician B only

c. Both A and B

d. Neither A nor B

To determine

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

Explanation

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...
