Function Test
-- Connect the scan tool.
-- Turn the ignition to the ON position.
-- Using the scan tool, Check the specified value of the Manifold Absolute Pressure (MAP) Sensor -G71- ignition on, engine off:
| Diagnostic text | Specified value |
|---|---|
| Intake manifold pressure | approx. 100 kPa |
If the specified value was obtained:
-- Condition is not present at this time. Check connections for loose or damaged terminals and check harness for an intermittent short.
If the specified value was Not obtained:
Test sequence
-- Disconnect the Manifold Absolute Pressure (MAP) Sensor -G71- electrical harness connector.
-- Start the engine and run at idle speed.
-- Using a multimeter, check the Manifold Absolute Pressure (MAP) Sensor -G71- electrical harness connector terminals 1 to 3 for voltage.
Specification: above 4.4 V
-- Using a multimeter, check the Manifold Absolute Pressure (MAP) Sensor -G71- electrical harness connector terminals 1 to 4 for voltage.
Specification: above 4.8 V
-- Switch the ignition OFF.
If the specified values were obtained:
-- Replace Manifold Absolute Pressure (MAP) Sensor -G71-.
If the specified values were Not obtained:
