General Information

Special tools and workshop equipment required 

• Evaporative Emissions Tester :KLI9210 
• Hose Clamps Up to 25 mm Dia. :VAS3094 
• Vehicle Diagnostic Tester

Use of the following tools depend on the vehicle model being tested:

Special tools and workshop equipment required 

• Evaporative Emissions Tester - Adapter 52 :KLI9210/52 
• Evaporative Emissions Tester - Adapter 54 :KLI9210/54 
• Evaporative Emissions Tester - Adapter 57 :KLI9210/57 

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

The Evaporative Emissions Tester :KLI9210  allows testing using nitrogen to pressurize the EVAP system. A smoke generator or ultrasonic tester is then used to locate the source of EVAP system concerns.

The procedure in this service information the general use of the Evaporative Emissions Tester :KLI9210  . It is intended as a guideline, as EVAP systems vary between models.

Testing LDP Equipped Vehicles with Leak Detection Pump -V144-

Leak detection monitoring was implemented in vehicles beginning in MY 1998 with the Leak Detection Pump (LDP) Leak Detection Pump -V144-.

Testing NVLD Equipped Vehicles with Fuel Tank Leak Detection Control Module

Starting in MY 2011, some vehicles began to employ the fuel tank leak detection control module to replace LDP for EVAP system monitoring.
