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.
