Auxiliary Port Valve (APV) Motor Inspection

AUXILIARY PORT VALVE (APV) MOTOR INSPECTION [13B-MSP]

Resistance Inspection

1. Remove the APV motor. Overhaul

2. Measure the resistance between the APV motor terminals.






- If not as specified, replace the APV motor. Overhaul

- APV motor resistance
8-50 ohms [20 °C {68 °F}]

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. Overhaul

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 any malfunction, replace the APV motor. Overhaul
- If as specified, carry out the "Circuit Open/Short Inspection".





Circuit Open/Short Inspection

1. Disconnect the PCM connector. Service and Repair

2. Inspect the following wiring harnesses for open or short (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 2F
- APV motor terminal D and PCM terminal 2D

Short circuit

- If there is no 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
