Note
•  Perform the following inspection only when directed.

Resistance Inspection

1.  Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION[LF, L3].)

2.  Disconnect the negative battery cable.

3.  Disconnect the throttle body connector.

4.  Measure the resistance between throttle actuator terminals E and F.

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

Open circuit

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


Short circuit

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