DTC Troubleshooting (cont’d)
EVAP System High Purge Flow
(2005-2006 models)
1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. 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, or
the EVAP canister vent shut valve and the ECM/
PCM.
Go to step 4.
4. Turn the ignition switch OFF.
5. Replace the EVAP canister purge valve (see page
11-412).
6. Turn the ignition switch ON (II).
7. Reset the ECM/PCM with the HDS.
8. Do the ECM/PCM idle learn procedure (see page
11-349).
9. 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, or
the EVAP canister vent shut valve and the ECM/
PCM, then go to step 1.

1. Turn the ignition switch ON (II).
2. Measure voltage between ECM/PCM connector
terminal B21 and body ground.
Go to step 3.
Go to step 8.
3. Turn the ignition switch OFF.
4. Disconnect the vacuum hose (A) from the EVAP
canister purge valve (B) in the engine compartment
and connect the vacuum pump/gauge, 0
30 in.Hg,
to the hose.
5. Connect ECM/PCM connector terminal B21 to body
ground with a jumper wire.
6. Turn the ignition switch ON (II).
7. Apply vacuum to the hose.
Replace the EVAP canister purge valve
(see page 11-412).
Go to step 16.
8. Turn the ignition switch OFF.
9. Disconnect ECM/PCM connector B (24P).
10. Connect ECM/PCM connector terminal B21 to body
ground with a jumper wire.

11. Disconnect the EVAP canister purge valve 2P
connector.
12. Check for continuity between EVAP canister purge
valve 2P connector terminal No. 2 and body ground.
Go to step 13.
Repair open in the wire between the EVAP
canister purge valve the ECM/PCM (B21).
13. Turn the ignition switch ON (II).
14. Measure voltage between EVAP canister purge
valve 2P connector terminal No. 1 and body ground.
Go to step 15.
Repair open in the wire between the EVAP
canister purge valve and the No. 4 ACG (10 A) fuse
in the under-dash fuse/relay box.
15. Measure resistance between EVAP canister purge
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 purge valve
(see page 11-412).
16. Measure voltage between ECM/PCM connector
terminal E21 and body ground.
Go to step 17.
Go to step 22.

17. Turn the ignition switch OFF.
18. Disconnect the vacuum hose from the EVAP
canister vent filter line (A) and connect the vacuum
pump/gauge, 0
30 in.Hg, to the hose.
19. Connect ECM/PCM connector terminal E21 to body
ground with a jumper wire.
20. Turn the ignition switch ON (II).
21. Apply vacuum to the hose.
Inspect the vacuum line between the EVAP
canister purge valve and the EVAP canister.
Replace the EVAP canister vent shut valve
(see page 11-474).
22. Turn the ignition switch OFF.
23. Disconnect ECM connector E (31P).
24. Connect ECM/PCM connector terminal E21 to body
ground with a jumper wire.
25. Disconnect the EVAP canister vent shut valve 2P
connector.
26. Check for continuity between EVAP canister vent
shut valve 2P connector terminal No. 2 and body
ground.
Go to step 27.
Repair open in the wire between the EVAP
canister vent shut valve and the ECM/PCM (E21).
