Manifold Pressure/Vacuum Sensor: Testing and Inspection

Pressure Sensor Schematic

The intake air flow measuring system is a pressure sensor connected with a hose to the intake plenum.  A faulty pressure sensor will set code 23 in
the on-board diagnostic system.  A disconnected or broken pressure sensor hose will set code 65.  Refer to the schematic diagram and test the sensor
with the diagnostic chart.
