New Jersey Inspections End Use of Dynamometers

(TRENTON) – The New Jersey Motor Vehicle Commission (MVC) today announced that, as of April 1, 2009, the State’s Enhanced Inspection and Maintenance (I/M) Program will no longer use dynamometers during the inspection of motor vehicles at its Centralized Inspection Facilities.

The dynamometer (or dyno for short) was first introduced into the inspection process in 1999 and is a machine that was used in the emissions testing phase in order to help the State of New Jersey meet federal clean air standards.

With advancements in technology, and the fact that most cars now traveling the roadways are newer models, the Enhanced I/M Program began utilizing On-Board Diagnostic (OBD) testing for on vehicles 1996 and newer. Older vehicles were subject to the dynamometer testing, but will now be done via two-speed idle (TSI).
