51.366 (a)(2)(i) Initial Visual Inspection Failing by model year and vehicle type

The Visual Inspection is performed on a vehcile any time there is a Two-Speed_Idle (TSI) test. The Visual Inspections checks for that key emission control equipment is present and
there are no signs of tampering. The Visual Inspection includes checks for catalyst, PCV valve, EGR system, and air pump or air injection systems. Initial tests were considered those
tests with Test Counter = 1.

51.366 (a)(2)(i) Initial Gas Cap Tests Failing by model year and vehicle type

The gas cap functional test is performed on all vehicles receiving an emissions test that have gas caps compatable with the 10 different sytle gas cap adaptor in the I&M program. The
gas cap fails if it leaks more than 60 cubic centimeters per minute (cc/min) at a pressure of 30 inches of water. Initial tests were considered those tests with Test Counter = 1.

51.366 (a)(2)(ii) Transient 1st Retests Failing by model year and vehicle type

Any vehicles receiving a transient test with test counter = 2 were considered 1st transient retests. This would include those vehicles that failed the initial test (test counter = 1)
for a safety item that made the vehicle unsafe to test on the dynamometer. This is why there are more transient 1st retests than initial transient failures.

51.366 (a)(2)(iii) Transient 1st Retests Passing by model year and vehicle type

Any vehicles receiving a transient test with test counter = 2 were considered 1st transient retests. This would include those vehicles that failed the initial test (test counter = 1) for a safety
item that made the vehicle unsafe to test on the dynamometer. This is why there are more transient 1st retests than initial transient failures.

2000 Massachusetts I&M Program Test Data
51.366 (a)(2)(vi) Vehicles with no know final outcome (regardless of reason)
Vehicles with no know outcome are vehicles that failed the emissions test and show no record of passing the retest. The following methodolgy was used for this analysis: 1) Track vehicle VINs whose last emission test in 2000 was a fail 2) remove any of these vehciles
that showed a passing emissions test in the first 6 months of 2001

51.366 (5) Average change in Transient Test Emissions after repairs by model year and vehicle type


Average change in emissions due to repair was determined using the following method: calculate the average emissions for vehicles that failed the initial transient test, calculate the average emissions for initially failing vehicles that passed the transient retest, and calculate the percent
difference between the two averages. The overall averages by vehicle class and model year were determined by taking the sum of the weighted averages ([avg emissions] * [# of vehicles tested]) for each model year or vehicle class and dividing by the total number of vehicles tested for
the model year or vehicle class. For post-repair tests, the testcounter was greater than 1 and the VIN also failed a transient test with test counter = 1
