Dtc P0108: Manifold Absolute Pressure / Barometric Pressure Circuit High Input - Suzuki Swift Sport 2004 Service & Repair Manual

Step
4 MAP sensor power supply circuit check
1) Disconnect connectors from A/C refrigerant pressure
sensor (if equipped with A/C) with ignition switch turned
OFF.
2) Turn ON ignition switch, measure voltage between
engine ground and "GRY/RED" wire terminal of MAP
sensor connector.
Is voltage 4 – 6 V?
5 MAP sensor signal circuit check
1) Measure voltage between "RED/BLK" wire terminal of
MAP sensor connector and engine ground.
Is voltage 4 – 6 V?
6 MAP sensor signal circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between "C37-53" terminal of ECM
connector and vehicle body ground.
Is resistance infinity?
7 MAP sensor output signal check
1) Check MAP sensor according to "MAP Sensor
Inspection in Section 1C".
Is it in good condition?

Wiring Diagram
Refer to "DTC P0106: Manifold Absolute Pressure / Barometric Pressure Circuit Range / Performance"
DTC Detecting Condition and Trouble Area
DTC detecting condition
Manifold absolute pressure sensor output voltage is higher
than specified value for specified time continuously.
(1 driving cycle detection logic)
NOTE
When DTC P0113 and P0118 are indicated together, it is possible that "ORN" wire circuit is open.
DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch turned OFF.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Run engine at idle speed for 1 min.
4) Check DTC.

"GRY/RED" wire is
shorted to ground
circuit.
If wires are OK,
substitute a known-
good ECM and recheck.
Go to Step 6.
"RED/BLK" wire is
shorted to ground
circuit.
Faulty MAP sensor.
