Dtc P0108: Manifold Absolute Pressure Circuit High Input - Suzuki GRAND VITARA Owner's Manual

Step
6 MAP sensor signal circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between "C37-55" terminal of ECM
connector and vehicle body ground.
Is resistance infinity?
7 MAP sensor output signal check
1) Check MAP sensor according to "Manifold Absolute
Pressure (MAP) Sensor Inspection: in Section 1C".
Is it in good condition?

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, P0118 and P0533 are indicated together, it is possible that "GRY/GRN" 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 and warm up engine completely.
3) Run engine at idle speed for 1 min.
4) Check DTC and pending DTC.
