DTC P0105 (DTC No.11) Manifold Absolute Pressure (MAP) Circuit Malfunc-
tion
CIRCUIT DESCRIPTION
DTC CONFIRMATION PROCEDURE
1) Clear DTC, start engine and keep it at idle for 1 min.
2) Select “DTC” mode on scan tool and check DTC.
INSPECTION
DTC DETECTING CONDITION POSSIBLE CAUSE
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)“B/Bl” circuit open
“Lg/R” circuit open or shorted to ground
“G” circuit open or shorted to ground
MAP sensor malfunction
ECM malfunction
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
together, it is possible that “B/Bl” circuit is open.
Step Action Yes No
1Was “Engine Diag. Flow Table” performed? Go to Step 2. Go to “Engine Diag. Flow
Table”.
2 Check MAP Sensor and Its Circuit.
1) Connect scan tool to DLC with ignition
switch OFF. See Fig. 1.
2) Turn ignition switch ON.
3) Check intake manifold pressure.

6) Repeat above steps 5) 4 times.
7) Increase vehicle speed to about 50 mph (80 km/h) in 3rd gear or 2 range.
8) Release accelerator pedal and with engine brake applied, keep vehicle coasting (fuel cut condition) for
10sec. or more.
9) Stop vehicle (don’t turn ignition switch OFF) and run engine at idle for 2 min. After this step 9), if “Oxygen
Sensor Monitoring TEST COMPLETED” is displayed in “READINESS TESTS” mode and DTC is not dis-
played in “DTC” mode, confirmation test is completed.
If “TEST NOT COMPLTD” is still being displayed, proceed to next step 10).
10) Drive vehicle under usual driving condition for 10 min. (or vehicle is at a stop and run engine at idle for 10
min. or longer)
