NISSAN PICK-UP 1998 Repair Manual

When installing, use a new O-ring.
WARNING:
Do not touch the cooled fuel temperature switch with your
bare hand.
Oil pressure switch
1. Run engine at about 1,000 rpm.
2. Check continuity for oil pressure switch.
3. If oil pressure switch has malfunction, replace it.
Fuel heater relay
1. Check fuel heater relay operation.
2. If fuel heater relay does not operate, replace it.

Electrical Components Inspection
IACV-FICD solenoid valve
1. Disconnect IACV-FICD solenoid valve harness connectors
and vacuum hoses.
2. Connect solenoid valve connector to battery and adequate
vacuum hoses to the solenoid valve as shown in the figure.
3. Blow air into hoses.
If air flows: OK
If air does not flow: NG
If NG, replace IACV-FICD solenoid valve.
