Manifold absolute pressure sensor circuit
• Manifold absolute pressure sensor • TP sensor • ECM |
NOTE:
When DTC P0113, P0118 and P0123 are indicated together, it is possible that “BLK/BLU” wire circuit is open.
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.
DTC Troubleshooting
| Step | Action | YES | NO |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
MAP sensor and its circuit check
1)
Connect scan tool to DLC with ignition switch OFF.
2)
Turn ignition switch ON.
3)
Check intake manifold pressure displayed on scan tool.
Is it 127 kPa (37.5 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 in open or shorted to power circuit.
|
| 5 |
MAP sensor ground circuit check
1)
Measure resistance between “BLK/BLU” wire terminal of MAP sensor connector and engine ground with ignition switch turned OFF.
Is resistance below 5 Ω?
|
Go to Step 7.
|
Go to Step 6.
|
| 6 |
Ground circuit check
1)
Measure resistance between “E119-28” terminal of ECM connector and vehicle body ground.
Is resistance below 5 Ω?
|
“BLK/BLU” wire in open or high resistance circuit.
|
ECM grounds “E119-1”, “E117-2” and/or “E117-1” circuit in open or high resistance.
If wires are OK, substitute a known-good ECM and recheck.
|
| 7 |
MAP sensor signal circuit check
1)
Turn ON ignition switch.
2)
Measure voltage between “GRN” wire terminal of MAP sensor connector and engine ground.
Is voltage 4 – 6 V?
|
Go to Step 9.
|
Go to Step 8.
|
| 8 |
MAP sensor signal circuit check
1)
Disconnect connectors from ECM with ignition switch turned OFF.
2)
Measure resistance between “GRN” wire terminal of MAP sensor connector and “E119-15” terminal of ECM connector.
Is resistance below 2 Ω?
|
“GRN” wire shorted to power supply circuit.
|
“GRN” wire in open or high resistance circuit.
|
| 9 |
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.
