  1. Turn the ignition switch to ON (II).
  2. Note these recorded on-board snapshot parameters with the HDS: Max Value of FTP SENSOR Min Value of FTP SENSOR FUEL LEVEL
  3. Check the FUEL LEVEL in the DATA LIST with the HDS. Is the fuel level less than it is in on-board snapshot? YES -Go to next step. NO -Drain the fuel until the FUEL LEVEL is less than it is in the on-board snapshot, then go to next step.
  4. Take a snapshot with the HDS for 3 minutes without starting the engine.
  5. Check the recorded snapshot parameter with the HDS: Max Value of FTP SENSOR (FINE) Min Value of FTP SENSOR (FINE) Is the difference between the MAX and MIN values of the FTP SENSOR (FINE) about 0.67 kPa (0.2 inHg, 5 mmHg) or less? YES -Go to next step. NO -Go to 12 .
  6. Check the FTP SENSOR (FINE) in the recorded snapshot with the HDS. Does it vary 0.067 kPa (0.02 inHg, 0.5 mmHg) or more for 3 seconds? YES -Go to next step. NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the FTP sensor, the EVAP canister vent shut valve, and the PCM. Also check for a blockage in the EVAP vent hose.
  7. Turn the ignition switch to LOCK (0).
  8. Remove the FTP sensor.
  9. Reconnect the FTP sensor 3P connector.
  10. Turn the ignition switch to ON (II).
  11. Check the FTP SENSOR (FINE) in the DATA LIST with the HDS. Does it vary 0.067 kPa (0.02 inHg, 0.5 mmHg) or more for 3 seconds? YES -Replace the FTP sensor; 2WD (see «2WD model»(ref-360097-S40306521632010042600000) ), 4WD (see «4WD model»(ref-360097-S04434386242010042600000) ), then go to 28 . NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the FTP sensor, the EVAP canister vent shut valve, and the PCM. Also check for a blockage in the EVAP vent hose.
  12. Remove the fuel cap.
  13. Check the FTP SENSOR (FINE) in the DATA LIST with the HDS. Is the value about 0.67 kPa (0.2 inHg, 5 mmHg) or more, or about-0.67 kPa (-0.2 inHg,-5 mmHg) or less? YES -Reinstall the fuel cap, then go to 22 . NO -Go to next step.
  14. Turn the ignition switch to LOCK (0).
  15. Remove the FTP sensor.
  16. Reconnect the FTP sensor 3P connector.
  17. Turn the ignition switch to ON (II).
  18. Check the FTP SENSOR (FINE) in the DATA LIST with the HDS. Is the value about 0.67kPa (0.2 inHg, 5 mmHg) or more, or about -0.67 kPa (-0.2 inHg, -5mmHg) or less? YES -Remove the blockage in the EVAP vent hose, and replace it if needed, then go to 26 . NO -Go to next step.
  19. Turn the ignition switch to LOCK (0).
  20. Disconnect the FTP sensor 3P connector.
  21. Check for a blockage or damage at the FTP sensor ports (EVAP canister side and vent side). Is there any blockage or damage? YES -Remove the blockage, and replace the FTP sensor if needed; 2WD (see «2WD model»(ref-360097-S40306521632010042600000) ), 4WD (see «4WD model»(ref-360097-S04434386242010042600000) ), then go to 28 . NO -Replace the FTP sensor; 2WD (see «2WD model»(ref-360097-S40306521632010042600000) ), 4WD (see «4WD model»(ref-360097-S04434386242010042600000) ), then go to 28 .
  22. Turn the ignition switch to LOCK (0).
  23. Disconnect the fresh air hose (A) from the EVAP canister (B), then connect a vacuum pump/gauge, 0-30 inHg, in the EVAP vent shut valve as shown.
  24. Turn the ignition switch to ON (II).
  25. Try to apply vacuum to the valve (not more than 5.3 kPa (1.6 inHg, 40 mmHg)) while checking the FTP SENSOR (FINE) in the DATA LIST with the HDS. NOTE: To avoid damaging the FTP sensor, do not apply more than 5.3 kPa (1.6 inHg, 40 mmHg) of vacuum. Does the valve hold more than 1.3 kPa (0.4 inHg, 10 mmHg) of vacuum? YES -Replace the EVAP canister vent shut valve; 2WD (see «2WD model»(ref-360097-S40306521632010042600000) ), 4WD (see «4WD model»(ref-360097-S04434386242010042600000) ), then go to next step. NO -Remove the blockage in the fresh air hose, and replace it if needed, then go to next step.
  26. Turn the ignition switch to LOCK (0).
  27. Reconnect all connectors and the fresh air hose.
  28. Turn the ignition switch to ON (II).
  29. Reset the PCM with the HDS.
  30. Do the PCM idle learn procedure (see «IDLE SPEED INSPECTION»(ref-360079-S14524315512010042600000) ).
  31. Take a snapshot with the HDS for 3 minutes without starting the engine.
  32. Check the recorded snapshot parameter with the HDS: Max Value of FTP SENSOR (FINE) Min Value of FTP SENSOR (FINE) Is the difference between the MAX and MIN values of the FTP SENSOR (FINE) about 0.67 kPa (0.2 inHg, 5 mmHg) or less? YES -Troubleshooting is complete. NO -Check for poor connections or loose terminals at the FTP sensor, the EVAP canister vent shut valve, and the PCM, then go to step 1.
