DTC Detecting Condition and Trouble Area
DTC detecting condition Trouble area
Difference between Max. manifold absolute pressure value and Min. manifold pressure value is less than 1.3 kPa (0.19 psi) at engine idling.
Difference between barometric pressure value and manifold pressure value is less than 33.3 kPa (4.83 psi) for 2 sec. at 2000 r/mini. or more.

DTC Confirmation Procedure
Check to make sure that the following conditions are satisfied when using this “DTC Confirmation Procedure”.
Intake air temperature at engine start: –10 °C (14 °F) to 80 °C (176 °F)
Intake air temperature: –10 °C (14 °F) to 70 °C (158 °F)
Engine coolant temperature: 70 °C (158 °F) to 150 °C (302 °F)
Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
1) Connect scan tool to DLC with ignition switch OFF.
2) Turn ON ignition switch and clear DTC using scan tool and warm up engine completely.
3) Run engine at idle speed for 1 min.
4) Check DTC and pending DTC.
DTC Troubleshooting
Step Action YES NO
Was “Engine and Emission Control System Check” performed?
Go to Step 2.
MAP sensor and its circuit check
1) Connect scan tool to DLC with ignition switch turned OFF.
2) Turn ignition switch ON.
3) Check DTC.
Is there DTC P0107 or DTC P0108?
Go to applicable DTC diag. flow.
Go to Step 3.
MAP sensor output signal check
1) Check MAP sensor according to Manifold Absolute Pressure (MAP) Sensor Inspection:M13A .
Is it in good condition?
Go to Step 4.
Faulty MAP sensor.
MAP sensor circuit check
Is circuit in good condition?
Go to Step 5.
Repair or replace.
Air intake system check
1) Check air intake system for clog or leak.
Is it in good condition?
Substitute a known-good ECM and recheck.
Repair or replace.
Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.
