Detected
 Vacuum/pressure gauge, 0 4 in.Hg, 07JAZ-001000B
 Vacuum pump/gauge, 0 30 in.Hg, Snap-on YA4000A
or equivalent, commercially available
NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3). 1. Check the fuel fill cap installation (The cap must say TIGHTEN TO CLICK. The cap should tighten 1/4 turn
after it is tight.).
Go to step 2.
Properly install the fuel fill cap, then go to
step 23.
2. Turn the ignition switch to ON (II).
3. Clear the DTC with the HDS.
4. Do the EVAP FUNCTION TEST in the INSPECTION MENU with the HDS.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the FTP sensor, the EVAP canister purge valve,
the EVAP canister vent shut valve, and the ECM/
PCM.
Go to step 5.
5. Check for a loose or damaged EVAP canister purge line between the intake manifold and the EVAP
canister purge valve.
Go to step 6.
Reconnect or repair the EVAP canister purge
line, then go to step 23. 6. Disconnect the vacuum hose (A) from the EVAP
canister purge valve (B) in the engine compartment,
and connect a T-fitting (C) between the vacuum
gauge, the vacuum pump/gauge, 0 30 in.Hg, and
the vacuum hose as shown.
7. Select EVAP PCS ON in the INSPECTION MENU with the HDS.
8. Slowly apply about 2 kPa (15 mmHg, 0.6 in.Hg) of vacuum to the hose.
Replace the EVAP canister purge valve, then
go to step 22.
Go to step 9.
Is the f uel f ill cap installed and properlytightened?
Is the result OK ?Is the line OK ? Does i t hol d v acuum?
