THROTTLE POSITION SENSOR

a. Resistance inspection.

1. Disconnect the throttle position sensor connector.
2. Using an ohmmeter, measure the resistance between terminals VC and E2.

Resistance: 2.5 - 5.0 k (Ohm)

3. Check the change of resistance between terminals VTA and E2.

Change of resistance:
The resistance value increases in proportion to the throttle lever opening value.
