INSPECTION PROCEDURE

1  Check voltage between terminal EGR of engine control module connector and body ground.

SST
ECM
(B) 75
EGR
FI6620

P  (1) Connect SST (check harness "A").
      (See page EG-404)
      SST 09990-0100
   (2) Warm up engine to normal operating
      temperature.

C  Measure voltage between terminal EGR of engine control module connector and body ground.

OK  Voltage:  9 — 14 V

NG                          OK  Go to step 4 .

2  Check resistance between terminals of VSV for EGR.

FI95632

P  Remove VSV for EGR. (See page EG-240)

C  Measure resistance between terminals of VSV for EGR.

OK  Resistance:  38.5 — 44.5 Ω at 20°C (68°F)

OK                          NG  Replace VSV for EGR.

3  Check for open and short in harness and connector between EFI main relay and VSV for EGR, VSV for EGR and engine control module. (See page IN-30)

OK                          NG  Repair or replace harness of connector.

Check and replace engine control module.
