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 (IG).
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / MAP.
5. Read the MAP value.

   OK

   Same value as the actual atmospheric pressure.

   HINT: 

   • Standard atmospheric pressure is 101 kPa(abs) [758 mmHg(abs)]. For every 100 m (328 ft) increase in altitude, pressure drops by 1 kPa (7.5 mmHg). The pressure also varies due to the weather (high atmospheric pressure, low atmospheric pressure).
   • Also, check "Atmosphere Pressure" in the Data List.

1. Disconnect the manifold absolute pressure sensor connector.
2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   C15-3 (VC) - C10-118 (VCPM)	Always	Below 1 Ω
   C15-2 (E2) - C10-119 (EPIM)	Always	Below 1 Ω
   C15-1 (PIM) - C10-87 (PIM)	Always	Below 1 Ω
   C15-3 (VC) or C10-118 (VCPM) - Body ground	Always	10 kΩ or higher
   C15-1 (PIM) or C10-87 (PIM) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
