2. Turn ignition switch "OFF".




3. Disconnect throttle position sensor harness connector.
4. Check resistance between terminals 02 and 03 while opening throttle valve manually.

Throttle Valve Conditions / Resistance at 25°C(77°F)
Completely closed / Approximately 0.5 K Ohms
Partially open / 0.5 - 4.0 K Ohms
Completely open / Approximately 4.0 K Ohms

If NG, replace throttle position sensor.
To adjust throttle position sensor, perform "BASIC INSPECTION".
