27. Turn the ignition switch ON (II).

28. Measure voltage between EVAP canister vent shut

valve 2P connector terminal No. 1 and body ground.

Go to step 29.

Repair open in the wire between the EVAP

canister vent shut valve and the No. 4 ACG (10 A)
fuse in the under-dash fuse/relay box.

29. Measure resistance between EVAP canister vent

shut valve 2P connector terminals No. 1 and No. 2.

Update the ECM/PCM if it does not have the

latest software, or substitute a known-good ECM/
PCM (see page 11-6), then recheck. If the symptom/
indication goes away with a known-good ECM/PCM,
replace the original ECM/PCM (see page 11-284).

Replace the EVAP canister vent shut valve

(see page 11-474).

DTC P0497:

Special Tools Required

YES

11-447

07JAZ-001000B

EVAP System Low Purge Flow

(2005-2006 models)

• Vacuum/pressure gauge, 0

4 in.Hg, 07JAZ-001000B

• Fuel pressure gauge attachment set 07AAJ-S6MA150
• Vacuum pump/gauge, 0

30 in.Hg, Snap-on YA4000A

or equivalent, commercially available

1. Check the fuel fill cap installation.

Go to step 2.

Properly install the fuel fill cap (the cap mast

say ‘‘Tighten to click’’). It should turn 1/4 turn after
it’s tight, then go to step 24.

2. Turn the ignition switch ON (II).

3. Clear the DTC with the HDS.

4. Do the EVAP FUNCTION TEST in the INSPECTION

MENU with the HDS.

Intermittent failure, 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) from the vacuum gauge
and the vacuum pump/gauge, 0

30 in.Hg, to the

EVAP canister purge valve as shown.

7. Do the EVAP PCS ON in the INSPECTION MENU

with the HDS.

8. Slowly apply about 2 kPa (0.6 in.Hg, 15 mmHg) of

vacuum to the hose.

Check for blockage on the EVAP canister

purge line between the intake manifold and the
EVAP canister purge valve. If the vacuum hose is
OK, replace the EVAP canister purge valve, then go
to step 23.

Go to step 9.

9. Reconnect the vacuum hose to the EVAP canister

purge valve.

(cont’d)

Is the f uel f ill cap installed and pr oper ly
tightened?

Is the r esult OK ?

Is the line OK ?

Does it hold vacuum?

10. Disconnect the vacuum hose from the EVAP

canister purge line (EVAP canister side), and
connect a T-fitting (A) from the vacuum gauge and
the vacuum pump/gauge, 0

30 in.Hg, to the hose

as shown.

11. Do the EVAP PCS ON in the INSPECTION MENU

with the HDS.

12. Slowly apply about 2 kPa (0.6 in.Hg, 15 mmHg) of

vacuum to the hose.

Check for a restricted EVAP canister purge

line between the EVAP canister purge valve and the
EVAP canister, then go to step 23.

Go to step 13.

13. Remove the FTP sensor with its connector

connected (see page 11-473).

14. Connect a T-fitting (A) from the vacuum gauge and

the vacuum pump/gauge, 0

30 in.Hg, to the FTP

sensor (B) as shown.

15. Note the FTP SENSOR reading in the DATA LIST

with the HDS.

16. Slowly apply about 1.3 kPa (0.4 in.Hg, 10 mmHg) of

vacuum to the hose.

17. Check the FTP SENSOR in the DATA LIST with the

HDS.

Go to step 18.

Replace the FTP sensor (see page 11-473),

then go to step 23.

Does it hold vacuum?

Is the dif f er ence mor e than 1.1 kPa ( 0.31 in.Hg,
8 mmHg.) bef or e and af ter applying vacuum?

18. Reconnect the vacuum hose to the EVAP canister

purge line (EVAP canister side) and reinstall the
FTP sensor.

19. Disconnect the vacuum hose (A) from the EVAP

canister purge line (EVAP canister purge valve side),
and connect a T-fitting (B) from the vacuum gauge
and the vacuum pump/gauge, 0

30 in.Hg, to the

hose.

20. Do the EVAP CVS ON in the INSPECTION MENU

with the HDS.

21. Slowly apply about 2 kPa (0.6 in.Hg, 15 mmHg) of

vacuum to the hose.

Check for blockage at the EVAP canister port,

then go to step 22.

Replace the EVAP canister vent shut valve,

then go to step 22.

22. Install the FTP sensor (see page 11-473).

23. Reconnect all hoses.

24. Turn the ignition switch ON (II).

25. Reset the ECM/PCM with the HDS.

26. Do the ECM/PCM idle learn procedure (see page

11-349).

27. Do the EVAP FUNCTION TEST in the INSPECTION

MENU with the HDS.

Troubleshooting is complete.

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, then go to step 1.

Does the hose hold vacuum?

Is the r esult OK ?
