1. Verify that the accelerator pedal position sensor is normal.
2. Visually inspect all accelerator pedal components for looseness.
3. Loosen the locknut that secures the idle switch.
4. Verify that the power circuit voltage.
5. Depress the accelerator pedal by hand and secure it when the voltage between the PCM terminals 10 (accelerator position detection signal) and 91 is within the range specified below.
Voltage range
6. Turn the idle switch under the condition in Step 5. Secure the idle switch when the continuity turns from ON to OFF, and tighten the locknut.
7. Release the accelerator pedal. Depress the accelerator pedal again and verify that the idle switch continuity changes from OFF to ON when the PCM terminal 10 voltage is within 1.0-1.2 V.
