EVAP System Monitor


OBD II regulations require that all vehicles equipped with an EVAP system be monitored for component integrity, system functionality and loss of hydrocarbons. The Enhanced EVAP system test is required to detect leaks as small as 0.040" in diameter. The test must detect leaks of 0.040-0.080" in diameter on fuel tanks larger than 25 gallons.
