Manifold Pressure/Vacuum Sensor: Testing and Inspection

FA20 ENGINE CONTROL: VACUUM SENSOR: ON-VEHICLE INSPECTION; 2013 MY FR-S [03/2012 -]

1. INSPECT MANIFOLD ABSOLUTE PRESSURE SENSOR

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON with the engine off.

(c) Inspect the manifold absolute pressure sensor.

(1) Enter the following menus: Powertrain / Engine / Data List / Atmosphere Pressure.

(2) Check the atmospheric pressure.

OK:

Almost the same as ambient pressure

HINT
* The standard atmospheric pressure is 101 kPa (1.03 kgf/cm2, 14.6 psi).
* The atmospheric pressure decreases by 1 kPa (0.01 kgf/cm2, 0.1 psi) as the altitude increases by 100 m.
* The atmospheric pressure varies depending on the weather.
