AUXILIARY PORT VALVE (APV) MOTOR INSPECTION (13B-MSP (HIGH POWER))

Resistance Inspection

1. Remove the APV motor. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)

2. Measure the resistance between the APV motor terminals using an ohmmeter.

• If not as specified, replace the APV motor. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)

• If as specified, carry out the "Circuit Open/Short Inspection".

APV motor resistance

8-50 ohms

Operation Inspection

Caution

• Applying voltage to the APV motor terminals for more than 3 s may damage the APV motor.

1. Disconnect the negative battery cable.

2. Remove the APV motor.

3. Apply 12 V with a current of 0.9-1.9 A to terminal B or D and verify that the gear moves.

• If there is no malfunction, carry out the "Circuit Open/Short Inspection".

• If there is any malfunction, replace the APV motor. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)

Circuit Open/Short Inspection

1. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)

Open circuit

• If there is no continuity, the circuit is open. Repair or replace the wiring harness.

– APV motor terminal B and PCM terminal 3J

– APV motor terminal D and PCM terminal 3G

Short circuit

• If there is continuity, the circuit is shorted. Repair or replace the wiring harness.

– APV motor terminal B and power supply

– APV motor terminal B and body GND

– APV motor terminal D and power supply

– APV motor terminal D and body GND
