Evaporative Emissions (EVAP) System Diagnosis Using KLI9210

Evaporative Emissions (EVAP) System Diagnosis Using KLI9210 EVAP Tester

Description
The leak detection threshold has recently changed from 1.0 mm (0.040 in.) to 0.5 mm (0.020 in.). These changes to EPA regulations regarding EVAP system integrity indicated that additional resources for more accurate EVAP system diagnosis are necessary.

The KLI9210 EVAP Tester allows testing using nitrogen to pressurize the EVAP system and a smoke generator or ultrasonic tester to locate the source of EVAP system concerns.

The following procedure will outline general use of the KLI9210 EVAP Tester. It is intended as a guideline, as EVAP systems vary between models.
