DTC Detecting Condition and Trouble Area
DTC detecting condition Trouble area
Manifold absolute pressure sensor output voltage is lower than specified value for specified time continuously.
(1 driving cycle detection logic)
• Manifold absolute pressure sensor circuit
• Manifold absolute pressure sensor
• TP sensor
• ECM
DTC Confirmation Procedure
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
1
Was “Engine and Emission Control System Check” performed?
Go to Step 2.
Go to Engine and Emission Control System Check:M13A with VVT .
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 intake manifold pressure displayed on scan tool.
Is it 0 kPa (0 in.Hg)?
Go to Step 3.
Intermittent trouble. Check for intermittent referring to Intermittent and Poor Connection Inspection .
3
MAP sensor power supply voltage check
1) Disconnect connector from MAP sensor with ignition switch turned OFF.
2) Check for proper connection of MAP sensor at “LT GRN/RED”, “GRN” and “BLK/BLU” wire terminals.
3) Turn ON ignition switch, measure voltage between engine ground and “LT GRN/RED” wire terminal of MAP sensor connector.
Is voltage 4 – 6 V?
Go to Step 5.
Go to Step 4.
4
MAP sensor power supply circuit check
1) Disconnect connector from TP sensor with ignition switch turned OFF.
2) Turn ON ignition switch, measure voltage between vehicle body ground and “LT GRN/ RED” wire terminal of MAP sensor connector.
Is voltage 4 – 6 V?
Faulty TP sensor.
“LT GRN/RED” wire shorted to ground circuit. If wires are OK, substitute a known-good ECM and recheck.
5
MAP sensor signal circuit check
1) Measure voltage between “GRN” wire terminal of MAP sensor connector and engine ground.
Is voltage 4 – 6 V?
Go to Step 7.
Go to Step 6.
6
MAP sensor signal circuit check
1) Disconnect connectors from ECM with ignition switch turned OFF.
2) Measure resistance between “E119-15” terminal of ECM connector and vehicle body ground.
Is resistance infinity?
Go to Step 7.
“GRN” wire shorted to ground circuit.
7
MAP sensor output signal check
1) Check MAP sensor according to Manifold Absolute Pressure (MAP) Sensor Inspection:M13A .
Is it in good condition?
Substitute a known-good ECM and recheck.
Faulty MAP sensor.
NOTE:
Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.
