Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Aids
To help locate intermittent leaks, use the Evaporative Emissions System Tester (J-41413-200) to introduce smoke into the EVAP system. Move all EVAP components while observing smoke with the High Intensity White Light (J-41413-SPT). To improve visibility of the smoke exiting the EVAP system, observe the suspected leak area from different angles with the High Intensity White Light. For intermittent conditions, refer to INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
