DTC P0107 [L3]

BME010200100W04

DTC P0107

MAP sensor circuit low input

DETECTION CONDITION

• PCM monitors input voltage from MAP sensor when intake air temperature is above 10 °C {50 °F}. If input voltage at PCM terminal 1J is below 0.01 V, PCM determines that MAP sensor circuit has malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if PCM detects the above malfunction condition during first drive cycle.
• PENDING CODE is available if PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.

POSSIBLE CAUSE

• MAP sensor malfunction
• Connector or terminal malfunction
• Short to ground in wiring between MAP sensor terminal D and PCM terminal 1J
• Open circuit in wiring between MAP sensor terminal C and PCM terminal 2K
• MAP sensor signal circuit and MAP sensor ground circuit are shorted each other
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
PERFORM DTC CONFIRMATION PROCEDURE
• Perform DTC CONFIRMATION PROCEDURE.
• Is same DTC present?
Yes
Go to next step.
No
Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure.
2
VERIFY MAP PID WHEN MAP SENSOR CONNECTOR IS DISCONNECTED
• Disconnect MAP sensor connector.
• Is voltage above 4.9 V?
Yes
Go to next step.
No
Go to step 4.
3
CHECK POWER SUPPLY CIRCUIT VOLTAGE AT MAP SENSOR CONNECTOR
Note
• If DTC P0122 and P2228 are also retrieved with P0107, go to CONSTANT VOLTAGE troubleshooting procedure.
• Turn ignition key to ON (Engine OFF).
• Measure voltage between MAP sensor terminal C (harness-side) and body ground.
• Is voltage within 4.5- 5.5 V?
Yes
Check for poor connection of MAP sensor terminal C (harness-side).
• Repair or replace terminal if necessary.
• If okay, replace MAP sensor.
Then go to Step 6.
No
Check for open circuit between PCM terminal 2K (harness-side) and MAP sensor terminal C (harness-side).
Repair or replace suspected harness, then go to Step 6.
4
INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND
• Turn ignition key to OFF.
• Disconnect PCM connector.
• Inspect continuity between MAP sensor terminal D (harness-side) and body ground.
• Is there continuity?
Yes
Repair or replace suspected harness, then go to Step 6.
No
Go to next step.
5
INSPECT MAP SENSOR SIGNAL AND GROUND CIRCUIT FOR SHORT EACH OTHER
• Inspect continuity between MAP sensor terminals D and A (harness-side).
• Is there continuity?
Yes
Repair or replace suspected harness, then go to next step.
No
Go to next step.
6
VERIFY TROUBLESHOOTING OF DTC P0107 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Turn ignition key to ON (Engine OFF).
• Clear DTC from memory using WDS or equivalent.
• Perform KOEO/KOER self-test.
• Is same DTC present?
Yes
Replace PCM, then go to next step.
No
Go to next step.
7
VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
• Is there any DTC present?
Yes
Go to applicable DTC troubleshooting.
No
Troubleshooting completed.
