I thought for newer cars they don't use the sniffers anymore?? minei s a 2002 so i thought they only did it with the OBD2 Diagnostic hooked up or do they use the sniffers along with that?? Because i have been searching the NJDMV site and it says they only inspect exhaust for Leaks, Noise and tampering of the Catalytic converter.
#4 The inspector then drives the car onto the dynamometer, a treadmill-like device that simulates regular driving. He or she puts the emissions probe in place, sets the computer then accelerates the engine.

Vehicles models 1998 (1996 effective January 1, 2004) and newer will receive the new OBD (On-Board Diagnostics) Test. The inspector will connect to the cars diagnostic control panel for a reading of how the vehicle is operating. Vehicles with dashboard lights illuminated or damaged OBD connectors will automatically fail. A common OBD failure is for Readiness. This means that the vehicle was not "ready" to be tested. Vehicles which fail for readiness most likely need to be driven. If you have just recently had service or disconnected the battery, the vehicle is likely to fail for readiness. Check your owners manual to understand the required drive cycle required to place your vehicle in a "ready" mode.
Is that what they mean by Probe?? sticking something in the tail pipe? because last May i only saw them hook up to My cars PCM i didnt see them stick anything in my tail pipe
