E.C.C. TROUBLE DIAGNOSES (Models with catalyzer) — Electrical Components Inspection (Cont'd)

EF & EC-149prose procedure

GA13DS, GA14DS & GA16DS engines (models with catalyzer).

Electrical Components Inspection (Cont'd)

VACUUM SWITCH

1
Disconnect vacuum switch connector.
2
Check continuity between terminals.
SEF360L
3
Apply vacuum to vacuum switch port with a hand vacuum pump.

Vacuum switch continuity

Applied vacuum −kPa (−bar, −mmHg, −inHg)	Continuity
Above 20.0 (200, 150, 5.91)	Yes
Below 20.0 (200, 150, 5.91)	No

Above 20.0 (200, 150, 5.91)

ContinuityYes

Below 20.0 (200, 150, 5.91)

ContinuityNo

If N.G. replace vacuum switch.

F.I. POT

Apply vacuum to F.I. pot with a handy vacuum pump. Rod of F.I. pot should pull out.

F.I.C.D. SOLENOID VALVE

1
Disconnect F.I.C.D. harness connector.
2
Check continuity between terminals. If N.G., replace F.I.C.D. solenoid valve.
SEF500L

E.G.R. CONTROL VALVE

Apply vacuum to E.G.R. vacuum port with a hand vacuum pump. E.G.R. control valve spring should lift.

B.P.T. VALVE

Plug one of two ports of B.P.T. valve. Apply a pressure above 0.490 kPa (4.90 mbar, 50 mmH₂O, 1.97 in H₂O) to check for leakage. If a leak is noted, replace valve.
