Code No. P0106: Manifold Absolute Pressure Circuit Range/Performance Problem
 
 
 
 
OPERATION
  • Check code No. P0107: Manifold absolute pressure sensor circuit low input (Refer to ).
  • Check code No. P0108: Manifold absolute pressure sensor circuit high input (Refer to ).
 
 
FUNCTION
  • Engine-ECU checks the manifold absolute pressure sensor for abnormal conditions.
 
 
TROUBLE JUDGEMENT
Check Conditions
  • Engine is running.
  • Throttle position sensors (main and sub) are normal.
Judgement Criterion
  • The difference between the manifold absolute pressure sensor output (actual value) and the manifold pressure estimated by the throttle position sensor (main) exceeds a predetermined value.
or
  • The difference between the manifold absolute pressure sensor output (actual value) and the manifold pressure estimated by the throttle position sensor (sub) exceeds a predetermined value.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Estimate the throttle opening degree and the inlet manifold pressure given by a normal sensor, and then carry out the fuel control.
  • Supercharging pressure is restricted.
 
 
PROBABLE CAUSES
  • Failed manifold absolute pressure sensor
  • Harness damage in manifold absolute pressure sensor circuit or loose connector contact
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE data list
  • Data list reference table (Refer to ).
    1. Item 8: Manifold absolute pressure sensor
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Go to Step 2.
 
STEP 2. Perform voltage measurement at manifold absolute pressure sensor connector.
  • Use special tool test harness (MB991709) to connect connector, and measure at pick-up harness.
  • Ignition switch: ON
  • Voltage between terminal engine-ECU MAP line and body earth.
  • Altitude 0 m: 3.8 - 4.2 V
  • Altitude 600 m: 3.5 - 3.9 V
  • Altitude 1,200 m: 3.3 - 3.7 V
  • Altitude 1,800 m: 3.0 - 3.4 V
Is the check result normal?
Go to Step 7.
Go to Step 3.
 
STEP 3. Perform voltage measurement at manifold absolute pressure sensor connector.
  • Disconnect connector, and measure at harness side.
  • Ignition switch: ON
  • Voltage between terminal engine-ECU MAP5 line and body earth.
OK: 4.9 - 5.1 V
Is the check result normal?
Go to Step 5.
Go to Step 4.
 
STEP 4. Check of damage in MAP5 line between manifold absolute pressure sensor connector and engine-ECU connector.
Is the check result normal?
Go to Step 8.
Repair the connector(s) or wiring harness.
 
STEP 5. Perform resistance measurement at manifold absolute pressure sensor connector.
  • Disconnect connector, and measure at harness side.
  • Resistance between terminal engine-ECU MAPE line and body earth.
OK: Continuity (2 Ω or less)
Is the check result normal?
Replace the manifold absolute pressure sensor.
Go to Step 6.
 
STEP 6. Check of damage in MAPE line between manifold absolute pressure sensor connector and engine-ECU connector.
Is the check result normal?
Go to Step 8.
Repair the connector(s) or wiring harness.
 
STEP 7. Check of damage in MAP line between manifold absolute pressure sensor connector and engine-ECU connector.
Is the check result normal?
Go to Step 8.
Repair the connector(s) or wiring harness.
