P0105 MAP Sensor Out of Range    

DTC (PGM-FI)

  1. Problem verification 1

    -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 0.18 V    

    Data List

    Do the current condition(s) match the threshold?

    YES 

    The failure is duplicated. Go to step 3.

    NO 

    Go to step 2.

  2. Problem verification 2

    Do the current condition(s) match the threshold?

    YES 

    The failure is duplicated. Go to step 7.

    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 .

    NO 

    Go to step 5.

  5. 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. Check for continuity between test points 1 and 2.

    Is there continuity?

    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 , then recheck. If DTC P0105 goes away and the PCM was substituted, replace the original PCM .

    NO 

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

  6. Shorted wire check (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.

    -4. Check for continuity 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 continuity?

    YES 

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

    NO 

    The PB wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM , then recheck. If DTC P0105 goes away and the PCM was substituted, replace the original PCM .

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

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

    -2. Disconnect the following connector.
