6-48 ENGINE GENERAL INFORMATION AND DIAGNOSIS
DTC P0105 (DTC No.11) Manifold Absolute Pressure (MAP) Circuit Malfunc-
tion
CIRCUIT DESCRIPTION
DTC DETECTING CONDITION
• MAP sensor signal is 0.19 V or lower.
(Low pressure – High vacuums – Low voltage)
• MAP sensor signal is 4.5 V or higher.
(High pressure – Low vacuums – High voltage)
NOTE:
• When DTC P0120 is indicated together, it is possible that "Lg/R" circuit is open.
• When DTC P0105 (No.11), P0110 (No.18) P0115 (No.19) P0120 (No.13) and P0460 are indicated

switch OFF. See Fig. 1.
2) Turn ignition switch ON.
3) Check intake manifold pressure.
Is it 126 kPa (37.2 inHg) or 0 kPa (0 inHg)?
Action
POSSIBLE CAUSE
• "B/Bl" circuit open
• "Lg/R" circuit open or shorted to ground
• "G" circuit open or shorted to ground
• MAP sensor malfunction
• ECM malfunction
Yes
Go to Step 2.
Go to Step 3.
No
Go to "Engine Diag. Flow
Table".
Intermittent trouble.
