DTC Code | DTC Name |
---|---|
P0107 | Manifold Absolute Pressure / Barometric Pressure Circuit Low Input |
P0108 | Manifold Absolute Pressure / Barometric Pressure Circuit High Input |
DESCRIPTION
Refer to DTC P0106 Click here.
DTC No. | DTC Detecting Condition | Trouble Area |
---|---|---|
P0107 | The output voltage from the manifold absolute pressure sensor less than 0.5 V for 0.5 seconds (1 trip detection logic). |
|
P0108 | The output voltage from the manifold absolute pressure sensor higher than 4.5 V for 0.5 seconds (1 trip detection logic). |
|
Tech Tips
When any of these DTCs are output, check the manifold absolute pressure using the Techstream. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / MAP.
Pressure Displayed | Malfunction |
---|---|
Approximately 0 kPa(abs) [0 mmHg(abs)] |
|
130 kPa(abs) [975 mmHg(abs)] or higher |
|
MONITOR DESCRIPTION
The ECM monitors the sensor voltage and uses this value to calculate the manifold absolute pressure. When the sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the manifold absolute pressure sensor and stores a DTC.
Example:
When the sensor output voltage remains less than 0.5 V, or higher than 4.5 V for 0.5 seconds, the ECM stores a DTC.

CONFIRMATION DRIVING PATTERN
Connect the Techstream to the DLC3.
Turn the power switch on (IG) and turn the Techstream on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the power switch off and wait for at least 30 seconds.
Turn the power switch on (IG) and turn the Techstream on.
Put the engine in inspection mode (maintenance mode) Click here.
Start the engine and wait 5 seconds or more.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Read the pending DTCs.
Tech Tips
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
Input the DTC: P0107 or P0108.
Check the DTC judgment result.
Techstream Display | Description |
---|---|
NORMAL |
|
ABNORMAL |

N/A |
|
Tech Tips
If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs Click here.
Tech Tips
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE
Tech Tips
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
READ VALUE USING TECHSTREAM (MAP)
Connect the Techstream to the DLC3.
Turn the power switch on (IG).
Turn the Techstream on.
Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / MAP.
Read the MAP value.
OK |
---|
Same value as the actual atmospheric pressure. |
Tech Tips
Standard atmospheric pressure is 101 kPa(abs) [760 mmHg(abs)]. For every 100 m (328 ft) increase in altitude, pressure drops by 1 kPa (7.5 mmHg). The pressure also varies due to the weather (high atmospheric pressure, low atmospheric pressure).
Also, check "Atmosphere Pressure" in the Data List.
