DTC P0107

MAP sensor circuit low input

DETECTION CONDITION

• The PCM monitors the input voltage from the MAP sensor when intake air temperature is above –10 °C {14 °F}. If the input voltage is below 0.1 V, the PCM determines that the MAP sensor circuit has a malfunction.

MONITORING CONDITIONS

• Calculated load: 13—32 %

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 2AG

• MAP sensor signal circuit and MAP sensor ground circuit are shorted each other

• Open circuit in wiring harness between MAP sensor terminal C and PCM terminal 2AU

• PCM malfunction

STEP

INSPECTION

ACTION

1

• 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 Service Bulletins and/or on-line 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

• Connect the M-MDS to DLC-2.

• Access MAP PID.

• Disconnect the MAP sensor connector.

• Is the voltage above 4.9 V?

Yes

Go to the next step.

No

Go to Step 5.

4

• 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.

  (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [LF].)

Then go to Step 7.

No

Inspect for open circuit in the wiring harness between PCM terminal 2AU (wiring harness-side) and MAP sensor terminal C (wiring harness-side).

Repair or replace the suspected wiring harness, then go to Step 7.

5

• Turn the ignition switch off.

• Disconnect the PCM connector.

• Inspect for 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 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.

7

• 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 M-MDS.

• 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

• 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.
