67 Pa. Code § 177.204 - Basis for failure
The basis for failure of the tests and procedures under this chapter shall be as follows:
(1)
I/M emission test. A
vehicle fails the I/M emission test if emissions exceed the following
standards:
(i)
Idle test
standards.
(A) Passenger cars and
trucks less than 6,000 pounds GVWR.
MODEL YEAR | CO% | HC (PPM) |
1975-1979 | 4.0 | 400 |
1980 | 3.0 | 300 |
1981-1992 | 1.2 | 220 |
1993 and newer | 1.0 | 130 |
(B) Trucks 6,000 pounds through 9,000 pounds
GVWR.
MODEL YEAR | CO% | HC (PPM) |
1975-1978 | 6.0 | 650 |
1979 | 4.0 | 400 |
1980 | 3.0 | 300 |
1981-1992 | 1.2 | 220 |
1993 and newer | 1.0 | 180 |
(C) Maximum exhaust dilution shall be
measured as at least 6% CO plus CO2 on vehicles subject
to a steady-state test as described in 40 CFR Part 51 , Subpart S, Appendix B
(relating to test procedures), which is adopted by reference.
(ii)
ASM test emission
standards. Model years 1981 and newer vehicles required to receive an
ASM emission inspection shall be subject to standards specified in Appendix A
(relating to acceleration simulation mode: Pennsylvania procedures, standards,
equipment specifications and quality control requirements).
(2)
OBD-I/M
check.
(i) Unless otherwise noted, a
vehicle fails the OBD-I/M check for any of the following:
(A) The MIL does not illuminate at all when
the ignition key is turned to the KOEO position.
(B) The DLC is missing, has been tampered
with, is otherwise inoperable or is inaccessible.
(C) The vehicle displays more than the
requisite number of readiness codes as "not ready," "not supported" or similar
message under §
177.203(b)(1)(i)-(iii)
(relating to test procedures), and there is no justification under §
177.203(b)(1)(iv)
for disregard of the readiness requirement.
(D) The MIL illuminates continuously or
flashes while the engine is running, even if no DTCs are present. If this
condition is present, the vehicle shall fail under this paragraph, not
subparagraph (ii), even if the MIL did not illuminate in the KOEO
position.
(E) Any DTCs are present
and the MIL status, as indicated by the scan tool, is commanded on, regardless
of whether or not the MIL is actually illuminated.
(ii) During the first test cycle of emission
inspection utilizing the OBD-I/M check in an I/M county or region, the
inability to locate or access a vehicle's DLC shall not be a basis for failure,
provided that the MIL illuminates when the ignition key is in the KOEO position
and does not illuminate continuously or flash while the engine is
running.
(3)
Evaporative emission system function test (gas cap test)
standards. A vehicle shall fail the gas cap test if at any time during
the gas cap test the pressure drops from the starting pressure by more than 6
inches of water, causing the test to be terminated. If the pressure does not
drop more than 6 inches during the test, the vehicle shall pass the gas cap
test.
(4)
Visual inspection
of vehicle emission control system. A vehicle shall fail the visual
inspection if applicable required emission control equipment specified in
§
177.203(d) is not
present, is not properly connected or is not the correct type for the certified
configuration.
(5)
Subsequent test procedures and bases for failure approved by the
EPA. If the EPA develops or approves other test procedures and bases
for failure of test procedures, including the test procedures prescribed in
this section, the Department may adopt these subsequently approved test
procedures and bases for failure consistent with section 4706(e) of the Vehicle
Code (relating to prohibition on expenditures for emission inspection
program).
