Evaporative Emission System Leak Test

CAUTION:

The evaporative emission system must not be pressurized to more than 3.48 kPa (14 in/H2O) or damage to the evaporative emission system may occur.

Connect evaporative emission (EVAP) system tester SST (134-01049) or equivalent at the evaporative emission test port.
Access Output Test Mode using WDS or equivalent tester. See ON - BOARD DIAGNOSTIC TESTS .
Select EVAPCV PID.
Select ALL OFF mode and press START to close the canister vent solenoid.
NOTE:
- Output Test Mode will default to its normal state after 10 minutes, after the vehicle is started or after cycling the key OFF then ON.
Follow the tester instruction:
- If the system passed leak test, no leak exists.
- If the system failed leak test, perform See PINPOINT TEST 10: FUEL LINE PRESSURE/FUEL PRESSURE HOLD INSPECTION .
NOTE:
- The leak tester detects smaller leak than minimum requirement in the PCM. Drive cycle procedure should be final confirmation method.
