DTC Troubleshooting
NOTE
Before this troubleshooting is performed, read the precautions for DTC troubleshooting referring to
"Precautions for DTC Troubleshooting".
Step
1
Was "Engine and Emission Control System Check"
performed?
2
MAP sensor and its circuit check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch.
3) Check DTC.
Is there DTC P0107 or DTC P0108?
3
MAP sensor output signal check
1) Check MAP sensor according to "Manifold Absolute
Pressure (MAP) Sensor Inspection (If Equipped) in
Section 1C".
Is it in good condition?
4
MAP sensor circuit check
1) Check MAP sensor circuit referring to Step 3 to 6 of
"DTC P0107: Manifold Absolute Pressure Circuit Low
Input" or Step 3 to 8 of "DTC P0108: Manifold Absolute
Pressure Circuit High Input".
Is circuit in good condition?
5
Air intake system check
1) Check air intake system for clog or leak.
Is it in good condition?
DTC P0107: Manifold Absolute Pressure Circuit Low Input
Wiring Diagram
Refer to "DTC P0106: Manifold Absolute Pressure Range / Performance".
DTC Detecting Condition and Trouble Area
DTC detecting condition
Manifold absolute pressure sensor output voltage is lower
than specified value for specified time.
(1 driving cycle detection logic)
DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch turned 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.
Action
Yes
Go to Step 2.
Go to applicable DTC
diag. flow.
Go to Step 4.
Go to Step 5.
Substitute a known-
good ECM and recheck.
Trouble area
• Manifold absolute pressure sensor circuit
• Manifold absolute pressure sensor
• A/C refrigerant pressure sensor (if equipped with A/C)
• ECM
No
Go to "Engine and
Emission Control
System Check".
Go to Step 3.
Faulty MAP sensor.
Repair or replace.
