ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT NO. 1 ELECTRONIC FUEL INJECTION MAIN RELAY (EFI-MAIN NO. 1)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Battery voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the No. 1 electronic fuel injection main relay (EFI-MAIN NO. 1).

2. INSPECT NO. 2 ELECTRONIC FUEL INJECTION MAIN RELAY (EFI-MAIN NO. 2)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Battery voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the No. 2 electronic fuel injection main relay (EFI-MAIN NO. 2).

3. INSPECT NO. 3 ELECTRONIC FUEL INJECTION MAIN RELAY (EFI-MAIN NO. 3)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Battery voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the No. 3 electronic fuel injection main relay (EFI-MAIN NO. 3).

4. INSPECT INJECTOR RELAY (D INJ)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Battery voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the injector relay (D INJ).

5. INSPECT VVT RELAY (VVT)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Battery voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the VVT relay (VVT).

6. INSPECT NO. 2 IGNITION RELAY (IG2 NO. 1)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Battery voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the No. 2 ignition relay (IG2 NO. 1).
