1.CHECK MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR
Turn ignition switch OFF.
Remove MAP sensor with its harness connector.
Install pressure pump (A) to MAP sensor (1).
Turn ignition switch ON.
Check the voltage between ECM harness connector terminals under the following conditions.
NOTE:
Always calibrate the pressure pump gauge when using it.
Inspection should be done at room temperature [10 - 30°C (50 - 86°F)].
