STEP 1. Using scan tool (M.U.T.-IIISE), check data list item 211: Fuel Tank Pressure Sensor.
caution | To prevent damage to scan tool (M.U.T.-IIISE), always turn off the power supply mode of the electric motor switch before connecting or disconnecting scan tool (M.U.T.-IIISE). |
(1) Connect scan tool (M.U.T.-IIISE). Refer to HOW TO CONNECT THE SCAN TOOL (M.U.T.-IIISE) . (2) Turn on the power supply mode of the electric motor switch.
(3) Remove the fuel cap.
(4) Set scan tool (M.U.T.-IIISE) to the data reading mode for item 211, Fuel Tank Pressure Sensor.- When altitude is 0 m (0 foot), 101 kPa (29.8 in.Hg).
- When altitude is 600 m (1,969 feet), 95 kPa (28.1 in.Hg).
- When altitude is 1,200 m (3,937 feet), 88 kPa (26.0 in.Hg).
- When altitude is 1,800 m (5,906 feet), 81 kPa (23.9 in.Hg).
(5) Turn off the power supply mode of the electric motor switch.
Is the sensor operating properly?
It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting / Inspection Service Points - How to Cope with Intermittent Malfunctions . Go to Step 2.
STEP 2. Check the continuity at fuel tank pressure sensor connector.
STEP 3. Check of open circuit and harness damage in FPRE line between fuel tank pressure sensor connector and ECM connector.
STEP 4. Using scan tool (M.U.T.-IIISE), check data list item 211: Fuel Tank Pressure Sensor.
(1) Turn on the power supply mode of the electric motor switch.
(2) Remove the fuel cap.
(3) Set scan tool (M.U.T.-IIISE) to the data reading mode for item 211, Fuel Tank Pressure Sensor.- When altitude is 0 m (0 foot), 101 kPa (29.8 in.Hg).
- When altitude is 600 m (1,969 feet), 95 kPa (28.1 in.Hg).
- When altitude is 1,200 m (3,937 feet), 88 kPa (26.0 in.Hg).
- When altitude is 1,800 m (5,906 feet), 81 kPa (23.9 in.Hg).
(4) Turn off the power supply mode of the electric motor switch.
Is the sensor operating properly?
It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting / Inspection Service Points - How to Cope with Intermittent Malfunctions . Replace the ECM (Refer to Removal and Installation ). Then go to Step 7.
STEP 5. Check of short circuit to power supply in FDPS line between fuel tank pressure sensor connector and ECM connector.
STEP 6. Replace the fuel tank pressure sensor.
STEP 7. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 . (2) Check the diagnostic trouble code (DTC).
Is DTC P24D8 set?
Retry the troubleshooting. The inspection is complete.
