Functional Description:
Control power, has two-pin socket, one for the power supply pin, one
●
for grounding pin.
Secondary air injection solenoid valve at the Idle (3500 rpm below)
●
actuator.
At Idling, ECU control solenoid valve by the grounding circuit to be
●
moving or closing.
Testing Procedures:
Resistance Confirmation:
Use of the "meter" Ohm stalls ( ), measurement of the secondary air
●
injection solenoid valve resistance value.
Detection judge:
Resistance value = 26 ± 2.6 (20 )
Treatment of abnormal phenomena:
Secondary air injection solenoid valve internal short circuit or open
●
circuit, or coupler bad contact.
Check whether the abnormal wire harness lines.
●
Secondary air injection solenoid valve anomaly, the proposed
●
replacement of the new one.
