Which option shows the correct identification of the EGR system type depicted?

• A. Technician A
• B. Technician B
• C. Neither technician is correct
• D. Both Technicians A and B

Answer: (B)

Actuation method tells you what EGR system type you’re looking at. A vacuum-operated EGR valve is driven by engine vacuum and usually shows simple hoses feeding a diaphragm, with no electrical connector or wiring harness. An electronically controlled EGR valve, by contrast, has an electrical plug and wiring that the ECU uses to open and close the valve, often with a solenoid or motor on the valve body.

The depicted setup shows an EGR valve with an electrical connector and wiring, which is characteristic of an electronically controlled system. That’s why Technician B’s identification matches what’s shown. Technician A would be mistaken if their description relied on vacuum-only operation or misread the absence of electrical control.

So, the correct identification is the electronically controlled EGR valve type, which aligns with the image features.
