CAUTION
• To prevent damage to scan tool MB991958, always turn
the ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.
• To prevent not to confuse top and bottom of fuel pump
relay harness side connector, ensure the triangular
mark on the junction block and check the connector.
1. Check the operating of the fuel pump by using scan tool
MB991958 to force-drive the fuel pump.
2. If the fuel pump will not operate, check by using the
following procedure. If normal, check the fuel pump drive
circuit.
(1) Turn the ignition switch to the "LOCK" (OFF) position.
(2) Remove the instrument panel side cover (driver’s side).
(3) Remove the fuel pump relay (2), and apply battery
voltage to junction block side connector terminal number
4. Check that an operating sound can be heard from the
fuel pump.
NOTE: As the fuel pump is an in-tank type, the fuel pump
sound is hard to hear. Remove the fuel tank filler tube cap
and check from the tank inlet.
(4) Check for fuel pressure by pinching the fuel hose with
fingertips.
(5) Install the fuel pump relay (2) and instrument panel side
cover (driver’s side).

INTAKE AIR TEMPERATURE SENSOR CHECK
M1131002800472
1. Disconnect the volume airflow sensor connectors.
2. Measure resistance between terminals No. 5 and No. 6.
Standard value:
13
− 17 kΩ [at −20°C (−4°F)]
5.3
− 6.7 kΩ [at 0°C (32°F)]
2.3
− 3.0 kΩ [at 20°C (68°F)]
1.0
− 1.5 kΩ [at 40°C (104°F)]
0.56
− 0.76 kΩ [at 60°C (140°F)]
0.30
− 0.42 kΩ [at 80°C (176°F)]
3. If not within specifications, replace the volume airflow
sensor.
4. Measure resistance while heating the sensor using a hair
dryer.
Normal condition:
5. If resistance does not decrease as heat increases, replace
the volume airflow sensor assembly.
ENGINE COOLANT TEMPERATURE SENSOR
CHECK
M1131003100454
CAUTION
Be careful not to touch the connector (resin section) with
the tool when removing and installing.
1. Drain engine coolant, then remove the engine coolant
temperature sensor.
2. With the temperature sensing portion of engine coolant
temperature sensor immersed in hot water, check the
resistance.
Standard value:
14
− 17 kΩ [at −20°C (−4°F)]
5.1
− 6.5 kΩ [at 0°C (32°F)]
2.1
− 2.7 kΩ [at 20°C (68°F)]
0.9
− 1.3 kΩ [at 40°C (104°F)]
0.48
− 0.68 kΩ [at 60°C (140°F)]
0.26
− 0.36 kΩ [at 80°C (176°F)]
3. If resistance deviates from the standard value greatly,
replace the sensor.

4. Apply 3M
AAD part number 8731 or equivalent to threaded
portion.
5. Install the engine coolant temperature sensor and tighten it
to the specified torque.
Tightening torque: 29
± 10 N⋅m (22 ± 7 ft-lb)
THROTTLE POSITION SENSOR CHECK
M1131003200503
Required Special Tool:
• MB991348: Test Harness Set
.
Checking the Terminal Resistance
1. Disconnect the throttle position sensor connector.
2. Measure resistance between the throttle position sensor
side connector terminal No. 1 and terminal No. 4.
Standard value: 3.5
− 6.5 kΩ
3. Measure resistance between the throttle position sensor
side connector terminal No. 1 and terminal No. 3.
Normal condition:
4. If resistance is outside the standard value, or if it doesn't
change smoothly, replace the throttle position sensor.
NOTE: After replacement, the throttle position sensor should
be adjusted. (Refer to
.)
