Open circuit
- If there is no continuity, the circuit is open. Repair or replace the harness. VAD control solenoid valve terminal B (harness-side) and PCM terminal 42 VAD control solenoid valve terminal A (harness-side) and main relay terminal C (harness-side)
Short circuit
- If there is continuity, the circuit is shorted. Repair or replace the harness. VAD control solenoid valve terminal B (harness-side) and body GND VAD control solenoid valve terminal A (harness-side) and power supply
Scheme 432
- Remove the VAD check valve (one-way). (See «INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [AJ]»(ref-196915-S12790852492005101000000) .)
- Blow through A and verify that air flows from B.
- Blow through B and verify that air does not flow from A. If not as specified, replace the VAD check valve (one-way).
- If there is continuity, the circuit is shorted. Repair or replace the harness. Throttle actuator terminal B (harness-side) and power supply Throttle actuator terminal B (harness-side) and GND Throttle actuator terminal A (harness-side) and power supply Throttle actuator terminal A (harness-side) and GND
Scheme 433
- Remove in the order indicated in (Scheme 433).
- Install in the reverse order of removal.
