LATEST UPDATED SMOG CHECK INSPECTOR
EXAM | COMPREHENSIVE TEST BANK WITH
ANSWERS AND RATIONALES.
1. When a smog inspector inspects a 1992 vehicle
visually, he or she finds the top of the exhaust gas
recirculation (EGR) valve has been crushed down.
How should the technician enter this into the EIS
machine?
A. Defective for EGR
B. Modified for ECS
C. Modified for EGR
D. Tampered for ECS
**Correct Answer:** C
**Rationale:** A crushed EGR valve is physically
altered from original, requiring "modified" entry.
2. The vacuum line leading to the exhaust gas
recirculation (EGR) valve has been rubbing on the
intake manifold. The hose has a small leak in it as a
result. How would the smog inspector enter this into
the EIS machine?
A. Defective for EGR
,B. Modified for EGR
C. Disconnected for EGR
D. Fail for EGR
**Correct Answer:** A
**Rationale:** A leaking vacuum line is a defective
component, not intentionally modified.
3. An EVAP system reduces HC emissions, true or
false?
A. True
B. False
**Correct Answer:** A
**Rationale:** EVAP system prevents hydrocarbon
vapors from escaping into the atmosphere.
4. A vehicle fails the OBD II portion of an ASM smog
inspection for incomplete readiness monitors and no
repairs have been recently performed. There are no
diagnostic trouble codes stored in the vehicles
computers. Which of the following actions should the
smog inspector take next?
A. Advise the customer to drive the vehicle through a
complete drive cycle
,B. Advise the customer to have the vehicle diagnosed
and possibly repaired
C. Advise the customer to see the state referee for a
one time waiver
D. Advise the customer to have their vehicle retested
by someone smarter
**Correct Answer:** B
**Rationale:** Incomplete monitors without recent
repairs indicate a need for diagnosis.
5. A vehicle is in for a smog check inspection. It has
two tailpipes showing from the rear of the vehicle.
Upon closer inspection you notice the vehicle has a
V-style engine with two exhaust manifolds. The
exhaust system has two catalytic converters and two
mufflers. It has no blend pipe between the catalytic
converters and/or mufflers joining the two exhaust
systems together. How would this vehicle get entered
into the EIS machine?
A. Single exhaust
B. Modified exhaust
C. Defective exhaust
D. Dual exhaust
**Correct Answer:** D
, **Rationale:** Two independent exhaust systems with
no crossover constitute dual exhaust.
6. A vehicle is in for a smog check inspection. The
technician notices the vehicle has a Canadian
underhood label. The label makes no reference to
California or Federal certification. How should the
smog inspector proceed?
A. Test the vehicle as a California vehicle
B. Test the vehicle as a federal vehicle
C. Check for a BAR label and proceed accordingly
D. Refuse to test the vehicle
**Correct Answer:** C
**Rationale:** BAR referee label provides
certification information for non-US vehicles.
7. A vehicle is in for a smog inspection in an
enhanced area of the state. The vehicle is a mini
motorhome and the door jamb shows GVWR as 7960
lbs and a rear axle weight of 4500 lbs. How should the
smog inspector proceed?
A. Conduct an ASM test
B. Conduct a TSI test
C. Refer the customer to another location
