NOTE
Be sure the battery is fully charged.
Do not disconnect the connectors of the throttle body assy.
Special Tool - Throttle Sensor Setting Adapter: 57001 -1538
Main Throttle Sensor Input Voltage Connections to Adapter: Digital Meter (+) → W (sensor BL) lead Digital Meter (–) → BK (sensor BR/BK) lead
ECU Intake Air Temperature Sensor
Input Voltage
Standard: DC 4.75 5.25 V
If the reading is within the standard, check the main throttle sensor resistance (see Main Throttle Sensor Resistance Inspection).
If the reading is out of the standard, remove the ECU and check the wiring for continuity between harness connectors.
Special Tool - Hand Tester: 57001-1394
Wiring Continuity Inspection ECU Connector [A] ←→ Main Throttle Sensor Connector [B] BL lead (ECU terminal 9) [C] BR/BK lead (ECU terminal 13) [D]
If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
Brake Hose and Pipe Damage and Installation Condition Inspection
Inspect the brake hoses, pipes and fittings for deterioration,
cracks and signs of leakage.
The high pressure inside the brake line can cause fluid to
leak [A] or the hose to burst if the line is not properly maintained.
Bend and twist the rubber hose while examining
it.
Replace the ...
Check 3-4: Turn Signal Indicator Light (LED) Inspection
Connect the leads in the same circuit as Check 3-2.
Connect the terminal [5] to the battery (+) terminal.
Connect the terminal [6] to the battery (+) terminal.
Check that the turn signal indicator light (LED) [A] goes
on.
If the indicator light does not go on, replace the meter ...
Spark Plug Condition Inspection
Remove the spark plugs (see Spark Plug Replacement in
the Periodic Maintenance chapter).
Visually inspect the spark plugs.
If the spark plug center electrode [A] and/or side electrode
[B] are corroded or damaged, or if the insulator [C]
is cracked, replace the plug.
If the spark plug is ...
