DTC P0107, P0108; Manifold Absolute Pressure / Barometric Pressure Circuit Low Input [08/2015 - 08/2016]: 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 / Primary / MAP.

   Powertrain > Engine and ECT > Data List 

   Tester Display
   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, atmospheric pressure drops by approximately 1 kPa (7.5 mmHg). The pressure also varies due to the weather (high atmospheric pressure, low atmospheric pressure).
   • Check "Atmosphere Pressure" in the Data List.
