NOTE: This article applies to ’98–03 Accords, ’96–03 Civics, ’98–03 CR-Vs, and ’99–03 Odysseys. PGM Tester software SN320 and later versions let you do a function test of the EVAP system to check for leaks. You’ll find this test listed on the INSPECTION screen (see S/B 02-007, EVAP System Function Testing and Diagnostics With the PGM Tester, for details). If you’re working on a , ’01–02 Civic or a ’02 CR-V take a look at S/B 02-026, 2001–02 Civic and 2002 CR-V: MIL Comes On With DTC P1457, as well. Before doing any repair work, you should run the EVAP System Function Test to find out what caused a DTC P1456 [EVAP control system leakage (fuel tank system)] or DTC P1457 [EVAP control system leakage, (EVAP canistersystem)] to set. And after you’ve finished repairs, run the test again to make sure the repair was done right before returning the vehicle to your customer.
