INSPECTION PROCEDURE
NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data
the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary,
if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. PERFORM ACTIVE TEST USING TECHSTREAM (PURGE VSV)
(a) Connect the Techstream to the DLC3.
(b) Remove the vacuum hose of the purge VSV from the canister.
(c) Start the engine and turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Active Test / Activate the VSV for Evap Control.
(e) Check if air is sucked into the port when operating the purge VSV using the Techstream.
OK:
NG -- INSPECT PURGE VSV
OK -- CHECK FOR INTERMITTENT PROBLEMS
2. INSPECT PURGE VSV
(a) Inspect the purge VSV See: Powertrain Management/Emission Control Systems/Evaporative Emissions System/Canister Purge
Control Valve/Testing and Inspection.
NG -- REPLACE PURGE VSV
OK -- Continue to next step.
3. INSPECT PURGE VSV (POWER SOURCE)
(a) Disconnect the purge VSV connector.
(b) Turn the engine switch on (IG).
