Check point
Check/Cause
Action
1. Harness
Disconnect connectors between combination meter and
engine oil pressure switch.
Measure resistance between terminals and chassis
ground.
Engine oil pressure switch terminal wire YB and
chassis ground.
Combination meter connector terminal wire No.54
wire YB and chassis ground.
Standard resistance : 100k Ω or more
If resistance is abnormal, harness is faulty.

2. Engine oil pressure
Switch
After starting engine, check continuity between its
terminals.
There is no continuity in normal condition.
If there is continuity, engine oil pressure switch is faulty.

•
Replace engine oil
pressure switch.
3. Combination Meter
(Engine oil pressure
warning indicator lamp)
(1) When starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
Battery 12 V (+) terminal wire No.12 inlet wire Y and
ground terminal wire B
Starter switch (ACC) terminal wire No.11 inlet wire
BrB and ground terminal wire B
Standard voltage : 12 V or more
(2) When starter switch is ON, measure voltage between
combination meter engine oil pressure warning terminal
outlet wire No.54 wire YB and chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK but engine oil
pressure warning lamp remains on after starting engine,
combination meter is faulty.
