Sometimes techs under think and just hook up their smoke machine to the evap test port and ‘let her rip’ (maybe closing the vent solenoid) and other techs over think by trying to use their scan tool to run all sorts of tests watching the tank pressure sensor while ignoring the smoke machine. In this video clip, watch Dave explain the right combination of scan tool and smoke machine usage to find the source of your evap leak.

Ohm’s Law overview with Dave Hobbs. Watch Now.
Ohm’s law is taught in high school and college auto shop but often soon forgotten as something impractical for use in the shop. Nothing could be further from the truth. Knowing the simple relationship between amps, ohms and volts has become more important than ever as electrical systems become more complex and factory schematics and trouble trees less detailed. With a firm foundation in Ohms’s law, your DVOM, a circuit theory of operation and an accurate schematic you can troubleshoot any electrical problem!
