  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 HDS on-board snapshot screen
  3. Check the FUEL LEVEL in the DATA LIST with the HDS. Is the FUEL LEVEL less than it is in the on- board snapshot? YES -Go to step 4. NO -Drain the fuel until the FUEL LEVEL is less than it is in the on-board snapshot, then go to step 4.
  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) HDS snapshot screen 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 step 6. NO -Go to step 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 step 7. 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 connecter.
  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 (see «FTP SENSOR REPLACEMENT»(ref-336485-S03250968232009072700000) ), then go to step 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 fill 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 fill cap, then go to step 22 . NO -Go to step 14.
  14. Turn the ignition switch to LOCK (0).
  15. Remove the FTP sensor.
  16. Reconnect the FTP sensor 3P connecter.
  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 0.67 kPa (0.2 inHg, 5 mmHg) or more, or about -0.67 kPa (-0.2 inHg, -5 mmHg) or less? YES -Remove the blockage in the EVAP vent hose, and replace it if needed, then go to step 26 . NO -Go to step 19.
  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 (see «FTP SENSOR REPLACEMENT»(ref-336485-S03250968232009072700000) ), then go to step 28 . NO -Replace the FTP sensor (see «FTP SENSOR REPLACEMENT»(ref-336485-S03250968232009072700000) ), then go to step 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, to 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 (see «EVAP CANISTER VENT SHUT VALVE REPLACEMENT»(ref-336485-S41579901092009072700000) ), then go to step 26. NO -Remove the blockage in the fresh air hose, and replace it if needed, then go to step 26.
  26. Turn the ignition switch to LOCK (0).
  27. Reconnect all connecters 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 «PCM IDLE LEARN PROCEDURE»(ref-336473-S09468920992009072700000) ).
  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) HDS snapshot screen 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 .

Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ). If DTC P145C is indicated alone, do the troubleshooting for DTC P0496 and P0497 using freeze data for P145C. If DTC P0497 and P145C stored at the same time, check for a poor connection, a blockage, or damage at the EVAP canister purge line between the EVAP canister purge valve and the EVAP canister, or a stuck closed EVAP canister purge valve. If any of DTCs listed below are indicated at the same time as DTC P145C, troubleshoot those DTCs first, then recheck for P145C. P0496, P0497: EVAP system purge flow
