About the NM Vehicle Emissions Program
The NM emissions testing program consists of several parts. Your vehicle will undergo:
- Second-generation on-board diagnostic (OBD II) testing to check that all emissions components are working properly.
- A tailpipe exhaust analysis to measure emissions of carbon monoxide and hydrocarbon.
- A check of the pollution control equipment to make sure equipment is properly installed and connected.
- A visible emissions check for smoke from the tailpipe.
- A gas cap pressure check to make sure the gas cap has a tight enough seal.
