DTC P0105 (No.11): Manifold Absolute Pressure (MAP) Circuit Malfunction
Wiring Diagram
1. MAP sensor 3. To TP sensor and CO adjust resister (if equipped)
2. ECM 4. To other sensor
DTC Detecting Condition and Trouble Area
DTC detecting condition Trouble area
• 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)
• “BLK/BLU” circuit open
• “LT GRN/RED” circuit open or shorted to ground
• “GRN” circuit open or shorted to ground
• MAP sensor malfunction
• ECM malfunction
NOTE:
• When DTC P0120 (No.13) is indicated together, it is possible that “LT GRN/RED” circuit is open.
• When DTC P0105 (No.11), P0110 (No.18), P0115 (No.19) and P0120 (No.13) are indicated together, it is possible that “BLK/BLU” circuit is open.
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.
DTC Troubleshooting
Step Action YES NO
1
Was “Engine and Emission Control System Check” performed?
Go to Step 2.
Go to Engine and Emission Control System Check:M13A without VVT .
2
Check MAP sensor and its circuit
1) Connect scan tool to DLC with ignition switch OFF.
2) Turn ignition switch ON.
3) Check intake manifold pressure.
Is it 126 kPa (37.2 in.Hg) or 0 kPa (0 in.Hg)?
Go to Step 3.
Intermittent trouble. Check for intermittent referring to Intermittent and Poor Connection Inspection .
3
Check wire harness
1) Disconnect MAP sensor connector with ignition switch OFF.
2) Check for proper connection of MAP sensor at “GRN” and “BLK/BLU” wire terminals.
3) If OK, then with ignition switch ON, check voltage at each of “LT GRN/RED” and “GRN” wire terminals and body ground.
Is voltage about 4 – 6 V at each terminal?
Go to Step 4.
“LT GRN/RED” wire open or shorted to ground circuit or shorted to power circuit (See NOTE),
“GRN” wire open or shorted to ground, poor “E115-26” connection or “E115-22” connection.
If wire and connection are OK, confirm that MAP sensor is normal and then substitute a known-good ECM and recheck.
4
1) Check MAP sensor according to Manifold Absolute Pressure (MAP) Sensor Inspection:M13A .
Is it in good condition?
“LT GRN/RED” wire shorted to “GRN” wire, “BLK/BLU” wire open, poor “E115-10” connection.
If wire and connection are OK, substitute a known-good ECM and recheck.
Replace MAP sensor.
NOTE:
When battery voltage is applied to “LT GRN/RED” wire, it is possible that MAP sensor is also faulty.
