DTC P0107: Manifold Absolute Pressure / Barometric Pressure Circuit Low Input; DTC P0108: Manifold Absolute Pressure / Barometric Pressure Circuit High Input [10/2017 - 12/2021]: 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 / All Data / 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, pressure drops by 1 kPa (abs) (7.5 mmHg (abs)). Varies by weather (high atmospheric pressure, low atmospheric pressure).
   • Check "Atmosphere Pressure" in the Data List.
