DTC (PGM-FI)
- Fuel fill cap installation check
-1. Check the fuel fill cap (the cap must say TIGHTEN TO CLICK). It should turn 1/4 turn after it's tight, then it clicks.
Is the correct fuel fill cap installed and properly tightened?
YES
Go to step 2.
NO
Replace the fuel fill cap or tighten the cap.
- Fuel fill cap seal and fuel fill pipe mating surface visual check
-1. Check fuel fill cap seal (A) and the fuel fill pipe mating surface (B). Verify that the fuel fill cap tether cord (C) is not caught under the cap.
Is the fuel fill cap seal missing or damaged, is the fuel fill pipe damaged, or is the tether cord caught under the cap?
YES
Replace the fuel fill cap or the fuel fill pipe .
NO
Go to step 3.
- EVAP leak check module drain passage check
-1. Remove the fuel tank .
-2. Disconnect the drain hose (A) from the EVAP leak check module (B), then connect the pressure fitting of the vacuum pump/gauge, 0-30 inHg (C), to the drain hose as shown.
-3. Slowly pressurize the drain passage while watching the gauge to check the blockage in the drain passage.
Does it hold a pressure?
YES
Remove the blockage from them, or replace the part(s) if needed.
NO
Go to step 4.
- Problem verification
-1. Turn the vehicle to the ON mode.
-2. Clear the DTC with the HDS.
-3. Turn the vehicle to the OFF (LOCK) mode.
-4. Turn the vehicle to the ON mode.
-5. Select the EVAP TEST in the Function Test Menu, then select the EVAP Leak Check Module Test with the HDS.
EVAP TEST
Is the result OK?
YES
If the test result is PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the FTP sensor, the fuel vapor containment valve, and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot.
NO
The failure is duplicated. Go to step 5.
- FTP sensor leak check
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Remove the FTP sensor , then connect its 3P connector.
-3. Connect the T-fitting (A), the vacuum pump/gauge, 0-30 inHg (C), and the vacuum pump to the FTP sensor (B) as shown.
-4. Turn the vehicle to the ON mode.
-5. Check and record the FTP sensor reading in the DATA LIST with the HDS.
Signal Current conditions Values Unit Tank Internal Pressure Data List
-6. Slowly apply about 2 kPa (0.6 inHg, 15 mmHg) of vacuum to the hose.
NOTE: To avoid damaging the FTP sensor, do not apply more than 2 kPa (0.6 inHg, 15 mmHg) of vacuum.Does it hold vacuum for 1 minute?
YES
Go to step 6.
NO
- Fuel vapor hose leak check
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Install the FTP sensor .
-3. Remove the nut, then disconnect the fuel vapor hose (A) from the fuel vapor containment valve (B).
NOTE: To avoid damaging the fuel vapor hose, do not twist or bend the hose excessively.-4. Turn the vehicle to the ON mode.
-5. Check and record the FTP sensor reading in the DATA LIST with the HDS.

-6. Slowly apply about 2 kPa (0.6 inHg, 15 mmHg) of vacuum to the hose.
NOTE: To avoid damaging the FTP sensor, do not apply more than 2 kPa (0.6 inHg, 15 mmHg) of vacuum.Does it hold a vacuum?
YES
Replace the fuel vapor containment valve .
NO
