Engine General Information and Diagnosis: 1A-46
DTC P0105 (No. 11): Manifold Absolute Pressure (MAP) Circuit Malfunction
S3RH0A1104016
Wiring Diagram
7 ECM ground circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors from ECM.
3) Measure resistance between each “C41-1”, “C41-2” and
“C41-3” wire terminals of ECM connector and body
ground.
Is resistance 1
Ω
or less?
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good ECM and
recheck. Open or high resistance
wire in “BLK/ORN” or
“BLK” circuit.
8 Main relay circuit check
1) Using service wire, ground “G04-10” wire terminal of
ECM connector.
2) Turn ignition switch to ON position.
3) Measure voltage between each “G04-5” and “G04-6”
wire terminals of ECM connector and body ground.
Is voltage 10 – 14 V?
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good ECM and
recheck. Go to Step 9.
9 Main relay circuit check
1) Turn ignition switch to OFF position.
2) Measure resistance between each “G04-5” and “G04-6”
wire terminals of ECM connector and “BLK/RED” wire
terminal of main relay connector.
Is resistance 1
Ω
or less?
Open or high resistance
wire in “BRN/WHT”
circuit. Open or high resistance
in “BLK/RED” circuit.
