(4) Remove the service hole cover.

(5) Disconnect the fuel tank pump and gauge

assembly connector.

(6) Remove the fuel tank cap.

(7) When the fuel tank pump and gauge assembly

connector terminal is connected directly to the
battery, check if the sound of the fuel tank
pump operation can be heard. If no operating
sound is heard, replace the fuel tank pump
(Refer to GROUP 13C, On-vehicle Service

P.13C-3

).

NOTE: As the fuel tank pump is an in-tank
type, the fuel tank pump sound is hard to hear.
Then check the sound from the tank inlet.

(8) Install the fuel tank cap.
(9) Check for fuel pressure by pinching the fuel

hose with fingertips.

(10)Connect the fuel tank pump and gauge

assembly connector.

(11)Install the service hole cover.
(12)Return the floor carpet to the original state,

and install the rear scuff plate. (Refer to
GROUP 52A, Interior Trims

P.52A-11

).

(13)Return the rear seat assembly to the original

state.

1. Disconnect the manifold absolute pressure

sensor.

2. Measure resistance between terminals No. 3 and

No. 4.

Standard value:

13

− 17 kΩ (at −20°C)

5.3

− 6.7 kΩ (at 0°C)

2.3

− 3.0 kΩ (at 20°C)

1.0

− 1.5 kΩ (at 40°C)

0.56

− 0.76 kΩ (at 60°C)

0.30

− 0.42 kΩ (at 80°C)

3. Remove the manifold absolute pressure sensor.

4. Measure resistance while heating the sensor

using a hair drier.

Normal condition:

5. If the value deviates from the standard value or

the resistance remains unchanged, replace the
manifold absolute pressure sensor assembly.

6. Install the manifold absolute pressure sensor and

tighten it to the specified torque.

Tightening torque: 6.0
