DTC P0107 [LF]

B3E010201084W08

DTC P0107 | MAP sensor circuit low input
--- | ---

DETECTION CONDITION

• The PCM monitors the input voltage from the MAP sensor when the intake air temperature is above 10 °C {50 °F}. If the input voltage at PCM terminal 2AL is below 0.1V, the PCM determines that the MAP sensor circuit has a malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

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

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VERIFY MAP PID WHEN MAP SENSOR CONNECTOR IS DISCONNECTED • Disconnect the MAP sensor connector. • Connect the WDS or equivalent to DLC-2. • Access MAP PID. • Is the voltage above 4.9 V? | Yes | Go to the next step.
No | Go to Step 5.

INSPECT 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 the ignition switch to the ON position (Engine off).
• Measure the voltage between MAP sensor terminal C (wiring harness-side) and body ground.
• Is the voltage within 4.5- 5.5 V?

Yes

Inspect for poor connection at MAP sensor terminal C (wiring harness-side).
• Repair or replace the terminal if necessary.
• If there is no malfunction, replace the MAP sensor.
Then go to Step 7.

No | Inspect for open circuit in wiring harness between PCM terminal 2W (wiring harness-side) and MAP sensor terminal C (wiring harness-side). Repair or replace suspected wiring harness, then go to Step 7.
5 | INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect continuity between MAP sensor terminal D (wiring harness-side) and body ground. • Is there continuity? | Yes | Repair or replace the wiring harness, then go to Step 7.
No | Go to the next step.
6 | INSPECT MAP SENSOR SIGNAL AND GROUND CIRCUIT FOR SHORT EACH OTHER • Inspect for continuity between MAP sensor terminals D and A (wiring harness-side). • Is there continuity? | Yes | Repair or replace the wiring harness, then go to the next step.
No | Go to the next step.

VERIFY TROUBLESHOOTING OF DTC P0107 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Turn the ignition switch to the ON position (Engine off).
• Clear the DTC from the memory using the WDS or equivalent.
• Start the engine.
• Is the same DTC present?

Yes

Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [LF].)

No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [LF].) • Are any DTC present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE [LF].)
No | Troubleshooting completed.
