DTC P0107: Manifold Absolute Pressure / Barometric Pressure Circuit Low Input; DTC P0108: Manifold Absolute Pressure / Barometric Pressure Circuit High Input: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Data List / MAP.
5. Read the MAP value.

   OK

   Same value as the actual atmospheric pressure.

   HINT: 

   • Standard atmospheric pressure is 101 kPa. For every 100 m increase in altitude, pressure drops by 1 kPa. Varies by weather (high atmospheric pressure, low atmospheric pressure).
   • Also, check "Atmosphere Pressure" in the Data List.

NG → See step   2 

OK → See step   6

OK: Go to next step 

1. Replace the manifold absolute pressure sensor. Refer to REMOVAL .

NEXT: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON and turn the Techstream on.
3. Clear the DTC. Refer to DTC CHECK / CLEAR .
4. Turn the ignition switch off.
5. Turn the ignition switch to ON and wait for 2 seconds.
6. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
7. Read the DTCs.

2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance (Check for Open)

   Tester Connection	Condition	Specified Condition
   B80 - 3 (VC) - B57 - 88 (VPIM)	Always	Below 1 Ω
   B80 - 2 (E2) - B57 - 87 (EPIM)	Always	Below 1 Ω
   B80 - 1 (PIM) - B57 - 89 (PIM)	Always	Below 1 Ω

   Standard Resistance (Check for Short)

   Tester Connection	Condition	Specified Condition
   B80 - 3 (VC) or B57 - 88 (VPIM) - Body ground	Always	10 kΩ or higher
   B80 - 1 (PIM) or B57 - 89 (PIM) - Body ground	Always	10 kΩ or higher
