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. (See DTC CONFIRMATION PROCEDURE [L3].) • Is same DTC present? | Yes | Go to next step.
No | Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [L3].)
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.
(See KOEO/KOER SELF-TEST PROCEDURE [L3].)
• Is same DTC present?
Yes
Replace PCM, then go to next step.
(See PCM REMOVAL/INSTALLATION [L3].)
No | Go to next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [L3].) • Is there any DTC present? | Yes | Go to applicable DTC troubleshooting. (See DTC TABLE [L3].)
No | Troubleshooting completed.
