DTC Code | DTC Name |
---|---|
P0107 | Manifold Absolute Pressure / Barometric Pressure Circuit Low Input |
P0108 | Manifold Absolute Pressure / Barometric Pressure Circuit High Input |
DESCRIPTION
The manifold absolute pressure sensor detects the intake manifold pressure. The ECM determines the basic injection volume and injection advance timing based on the voltage output by the manifold absolute pressure sensor.
The manifold absolute pressure sensor monitors the absolute pressure inside the intake manifold (default is 0 kPa [0 mmHg, 0 in.Hg]). As a result the ECM controls the air fuel ratio at the proper level under any driving conditions.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory |
---|---|---|---|---|---|
P0107 | Manifold Absolute Pressure / Barometric Pressure Circuit Low Input |
After the engine is started, condition (a) continues for more than 0.5 seconds (1 trip detection logic): (a) Manifold absolute pressure sensor voltage is 0.1 V or less. |

If DTC P0107 and/or P0108 is stored, the following symptoms may appear:
Misfire
Combustion noise
Black smoke
White smoke
Lack of power
When DTC P0107 or P0108 is stored, check the intake manifold pressure by entering the following menus: Powertrain / Engine and ECT / Data List / All Data / MAP.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click hereНажмите здесь).
If DTCs relating to different systems are stored and they share terminal E2 as their ground, check this ground circuit first.
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
READ VALUE USING GTS (MAP)
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / MAP.
Powertrain > Engine and ECT > Data ListTester Display |

MAP |
Read the value.
OK |
---|
Same value as the actual atmospheric pressure. |
Standard atmospheric pressure is 101 kPa. For every 100 m increase in altitude, pressure drops by 1 kPa. Varies by weather (high atmospheric pressure, low atmospheric pressure).
Also, check "Atmosphere Pressure" in the Data List.

CHECK WHETHER DTC OUTPUT RECURS
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs.
Powertrain > Engine and ECT > Clear DTCsTurn the ignition switch off for 30 seconds or more.
Turn the GTS off.
Start the engine.
After the engine is started for 2 seconds, race the engine for 1 second.
Turn the GTS on.
Confirm that the DTC is not output.
Perform the following procedure using the GTS to determine whether or not the DTC judgment has been carried out.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs.
Powertrain > Engine and ECT > Clear DTCsTurn the ignition switch off for 30 seconds or more.
Turn the ignition switch to ON for 3 seconds and turn the GTS on.
After the engine is started for 2 seconds, race the engine for 1 second.
Confirm that the DTC is not output.
Perform the following procedure using the GTS to determine whether or not the DTC judgment has been carried out.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
