FUEL TANK DIFFERENTIAL PRESSURE SENSOR CHECK
Required Special Tool
- MB991658: Test Harness Set
Scheme 28
- Remove rear seat cushion assembly. Refer to «REAR SEAT ASSEMBLY»(ref-308269-S06254885892009020200000) .
- Remove the hole cover.
- Disconnect the fuel tank differential pressure sensor connector.
- Connect special tool MB991658 between the terminals of the disconnected connector.
- Turn the ignition switch to "ON" position and measure the voltage between terminal 1 and ground. Standard value: 2.0 - 3.0 V
- If not within the standard value, replace the fuel tank differential pressure sensor.
- Connect the fuel tank differential pressure sensor connector.
- Install the hole cover. Tightening torque: 1.5 ± 0.5 N.m (14 ± 4 in-lb)
- Install the rear seat cushion assembly.
Scheme 29
- Place a drain pan, and disconnect the fuel tank vapor hose A at pipe side. NOTE: If fuel leaks from the fuel leveling hose at this stage, the leveling valve may be defective.
- Open the fuel cap, and fill the fuel tank up.
- If fuel does not leak from the fuel tank vapor hose A with the fuel tank full, the leveling valve is normal. If it does leak, the leveling valve may be defective. Lower the fuel tank from the vehicle and replace the valve.
- Reconnect the fuel tank vapor hose A at the pipe side.

<< C >> FUEL HIGH-PRESSURE HOSE DISCONNECTION
| CAUTION | As there will be some pressure remaining in the fuel pipe line, cover it with a shop towel to prevent fuel from spraying out. |
>> C << FUEL HIGH-PRESSURE HOSE CONNECTION
| CAUTION | After installing, slightly pull the fuel high-pressure hose and ensure that there is no disengaged fuel high-pressure hose. Also confirm that there is approximately 3 mm (0.12 inch) play at this time. |
FUEL TANK SHUT-OFF VALVE CHECK
Check that the flapper of the fuel shut-off valve opens and closes as shown in the illustration.
