SMOG QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS 100%
CORRECT!!!
1. EIS Communication
Q: The EIS communicates information to _______ using ________. A: The
VID (Vehicle Information Database); the internet.
Explanation: The Emission Inspection System (EIS) and the OBD
Inspection System (OIS) must maintain a continuous internet connection to
communicate with the state’s Vehicle Information Database. This
connection is required to verify vehicle data, transmit test results, and
receive real-time updates from the BAR.
2. EGR Functional Test Requirements
Q: A Smog Inspection Technician must perform an EGR (Exhaust Gas
Recirculation) functional test on vehicles that are: A: 1976 – 1995 Vehicles
and Trucks.
Explanation: Per BAR inspection procedures, the functional check of the
EGR system is mandatory for vehicles model year 1995 and older that are
subject to a two-speed idle (TSI) test. For newer vehicles (2000+), the
OBDII system monitors the EGR functionality, rendering the manual
functional test unnecessary.
3. Visible Smoke Test Procedure
Q: How do you proceed when you observe smoke on the first snap of a
gasoline-fueled vehicle? A: Pass the vehicle; the first snap does not count.
Explanation: The visible smoke test procedure consists of three "snaps."
According to the official BAR protocol, the first snap is considered a pre-
conditioning or stabilization snap and is not used to determine a pass/fail
result. The vehicle is only evaluated for visible smoke during the subsequent
two snaps, as well as during the idle and crankcase (PCV) tests.
, . Which of the following vehicles are subject to the EGR Functional Test
(assuming the vehicle is equipped with EGR) -ANSWER ✔✔1984 Dodge truck
undergoing a Two-Speed Idle Test
The Smog Check program applies to all vehicles powered by: -ANSWER
✔✔Propane / Natural Gas
Technician A says "The EIS will not print out Smog Certificates." Technician B
says the vehicle inspection report can be used to show that a smog inspection was
done. Who is correct -ANSWER ✔✔Both
First emission control device -ANSWER ✔✔PCV, catalytic converters
what year did they stop testing the EGR for proper operation? -ANSWER ✔✔1995
What are the smog program areas that CA is divide into -ANSWER ✔✔Change of
Ownership Area, Basic Area, Enhanced Area
how are the program areas divided -ANSWER ✔✔by air quality
when do Vehicles require a smog inspection in the change of Ownership Area -
ANSWER ✔✔upon a change of ownership and initial registration in CA only
when do Vehicles require a smog inspection in the Basic and Enhanced Areas -
ANSWER ✔✔biannually and Initial registration in CA
