DTC P0107  : MAP Sensor Circuit Low Voltage

NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC Description Confirmed DTC Pending DTC
P0107 MAP Sensor Circuit Low Voltage    

DTC (PGM-FI)

  1. Problem verification

    -1. Turn the vehicle to the ON mode.

    -2. Check the parameter (s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    MAP Sensor Voltage Less than 0.23 V    

    Do the current condition (s) match the threshold?

    YES 

    The failure is duplicated. Go to step 2.

    NO 

    Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

  2. Determine possible failure area (MAP (PB) line, others)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Disconnect the following connector.

    MAP sensor 3P connector

    -3. Turn the vehicle to the ON mode.

    -4. Check the parameter (s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    MAP Sensor Voltage Less than 0.23 V    

    Do the current condition (s) match the threshold?

    YES 

    Go to step 5.

    NO 

    Go to step 3.

  3. Determine possible failure area (MAP sensor, others)

    -1. Measure the voltage between test points 1 and 2.

    Test condition Vehicle ON mode
      MAP sensor 3P connector: disconnected
    Test point 1 MAP sensor 3P connector (female terminals) No. 1:
    Test point 2 MAP sensor 3P connector (female terminals) No. 3:

    Is there about 5.0 V?

    YES 

    Replace the MAP sensor .

    NO 

    Go to step 4.

  4. Open wire check (VCC1 line)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Jump the SCS line with the HDS, and wait more than 1 minute.

    -3. Disconnect the following connector.

    PCM connector E (80P)

    -4. Measure the resistance between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      MAP sensor 3P connector: disconnected
      PCM connector E (80P) : disconnected
    Test point 1 MAP sensor 3P connector (female terminals) No. 3:
    Test point 2 PCM connector E (80P) No. 70

    Is there 1.0 Ω or less?

    YES 

    The VCC1 wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .

    NO 

    Repair an open in the VCC1 wire between the PCM (E70) and the MAP sensor.

  5. Shorted wire check (MAP (PB) line)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Jump the SCS line with the HDS, and wait more than 1 minute.

    -3. Disconnect the following connector.

    PCM connector E (80P)

    -4. Measure the resistance between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      MAP sensor 3P connector: disconnected
      PCM connector E (80P) : disconnected
    Test point 1 MAP sensor 3P connector (female terminals) No. 2:
    Test point 2 Body ground

    Is there 1 MΩ or more?

    YES 

    Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .

    NO 

    Repair a short in the MAP (PB) wire between the PCM (E56) and the MAP sensor.
