On-Vehicle Inspection

INSPECT THROTTLE BODY




a. Check for an operating sound.
1. Turn the ignition switch ON.
2. When turning the accelerator pedal position sensor lever, listen to a running sound of the motor. Also, check that there is no friction sound.
If operation is not as specified, check the throttle control motor, wiring and ECM.

b. Inspect the throttle position sensor.
1. Connect the hand-held tester to the DLC3.
2. Turn the ignition switch ON.
3. When turning the accelerator pedal position sensor lever to the full-open position, check the throttle valve opening percentage (THROTTLE POS) of the CURRENT DATA.

Standard throttle valve opening percentage:
60% or more

If the result is not as specified, check the accelerator pedal position sensor, wiring and ECM.
If the hand-held tester is not available, measure the voltage between the terminals (VTA1 - E2, VTA2 - E2) of the ECM connector.

c. Inspect the air assist system.
1. Start the engine and check that the MIL does not light up.
2. Warm up the engine to the normal operating temperature.
3. Switch the A/C compressor from ON to OFF, and check the idle speed.

Idle speed (Transmission in neutral): 700 ± 50 rpm

NOTE: Perform this inspection while no electrical load is applied.

d. Perform the driving test.
