DTC P0107:00

DTC P0107:00  MAP sensor circuit low input 
DETECTION CONDITION 
  • The PCM monitors the input voltage from the MAP sensor. If the input voltage is below 0.1 V for 5 s, 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.
  • FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
  • The DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • MAP sensor connector or terminals malfunction
  • Short to ground in wiring harness between MAP sensor terminal C and PCM terminal 2AU
  • PCM connector or terminals malfunction
  • Open circuit in wiring harness between MAP sensor terminal C and PCM terminal 2AU
  • Short to ground in wiring harness between MAP sensor terminal D and PCM terminal 2AG
  • MAP sensor signal circuit and ground circuit are shorted to each other
  • MAP sensor malfunction
  • PCM malfunction
G07864490
DIAGNOSTIC PROCEDURE

STEP INSPECTION ACTION
1 VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED 
  • Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
 Yes Go to the next step.
No Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2 VERIFY RELATED REPAIR INFORMATION AVAILABILITY 
  • 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 VERIFY PID DATA FOR MAP SENSOR MALFUNCTION 
  • Access the MAP PID using the M-MDS.

    (See ON-BOARD DIAGNOSTIC TEST ).

  • Disconnect the MAP sensor connector.
  • Is the voltage above 4.9 V?
 Yes Go to the next step.
No Go to Step 9.
4 INSPECT POWER SUPPLY CIRCUIT VOLTAGE AT MAP SENSOR CONNECTOR 
NOTE:
  • If DTC P0122:00 is also retrieved with P0107:00, go to CONSTANT VOLTAGE troubleshooting procedure.

  • Switch the ignition to ON (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 Go to the next step.
No Go to Step 6.
5 INSPECT MAP SENSOR CONNECTOR CONDITION 
  • Switch the ignition to oft.
  • Disconnect the MAP sensor connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Is there any malfunction?
 Yes Repair or replace the terminal and/or connector, then go to Step 12.
No Replace the MAP sensor, then go to Step 12.
(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION ).
6 INSPECT MAP SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND 
  • Switch the ignition to off.
  • Disconnect the MAP sensor connector.
  • Inspect for continuity between MAP sensor terminal C (wiring harness-side) and body ground.
  • Is there continuity?
 Yes If the short to ground circuit could be detected:
  • Repair or replace the wiring harness for a possible short to ground.

If the short to ground circuit could not be detected:

Go to Step 12.
No Go to the next step.
7 INSPECT PCM CONNECTOR CONDITION 
  • Disconnect the PCM connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Is there any malfunction?
 Yes Repair or replace the terminal and/or connector, then go to Step 12.
No Go to the next step.
8 INSPECT MAP SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT 
  • MAP sensor and PCM connectors are disconnected.
  • Inspect for continuity between MAP sensor terminal C (wiring harness-side) and PCM terminal 2AU (wiring harness-side).
  • Is there continuity?
 Yes Go to Step 12.
No Repair or replace the wiring harness for a possible open circuit, then go to Step 12.
9 INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND 
  • Switch the ignition to off.
  • Disconnect the MAP sensor and PCM connectors.
  • Inspect for continuity between MAP sensor terminal D (wiring harness-side) and body ground.
  • Is there continuity?
 Yes Repair or replace the wiring harness for a possible short to ground, then go to Step 12.
No Go to the next step.
10 INSPECT MAP SENSOR SIGNAL AND GROUND CIRCUITS FOR SHORT TO EACH OTHER 
  • MAP sensor and PCM connectors are disconnected.
  • Inspect for continuity between MAP sensor terminals D and A (wiring harness-side).
  • Is there continuity?
 Yes Repair or replace the malfunctioning wiring harness, then go to Step 12.
No Go to the next step.
11 INSPECT MAP SENSOR 
 Yes Replace the MAP sensor, then go to the next step.
(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION ).
No Go to the next step.
12 VERIFY DTC TROUBLESHOOTING COMPLETED 
  • Make sure to reconnect all disconnected connectors.
  • Switch the ignition to ON (engine off).
  • Clear the DTC from the PCM memory using the M-MDS.

    (See AFTER REPAIR PROCEDURE ).

  • Perform the KOEO or KOER self test.

    (See KOEO/KOER SELF TEST ).

  • Is the same DTC present?
 Yes Repeat the inspection from Step 1.

Go to the next step.
No Go to the next step.
13 VERIFY AFTER REPAIR PROCEDURE 
 Yes Go to the applicable DTC inspection.
(See DTC TABLE ).
No DTC troubleshooting completed.
