DTC P0107 (1.5 L Engine)

DTC P0107  : MAP Sensor Circuit Low Voltage

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

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	Less than 0.23	V

   Do the current condition (s) match the threshold?

   YES 

   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 (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	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. 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. 3:
   Test point 2	PCM connector E (80P) No. 70

   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 .

   NO 

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

5. 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.

   -3. Disconnect the following connector.

   PCM connector E (80P)

   -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 .
