id0113b5801300

Note
•  Perform the following inspection only when directed.

Resistance Inspection

1.  Remove the battery cover. (SeeBATTERY REMOVAL/INSTALLATION [L3 Turbo].)

2.  Disconnect the negative battery cable.

3.  Disconnect the throttle body connector.

4.  Measure the resistance between the throttle actuator terminals using a tester.

•  If not as specified, replace the throttle body. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo].)
•  If as specified, carry out the “Circuit Open/Short Inspection”.

Open circuit

•  If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
―  Throttle actuator terminal F and PCM terminal 2A
―  Throttle actuator terminal E and PCM terminal 2B


Short circuit

•  If there is continuity, there is a short circuit. Repair or replace the wiring harness.
―  Throttle actuator terminal F and power supply
―  Throttle actuator terminal F and ground
―  Throttle actuator terminal E and power supply
―  Throttle actuator terminal E and ground
