MAP Sensor

MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR
Inspection
1. Warm up the engine to normal operating temperature and let it idle.
2. Carry out the intake-air system inspection.




3. Measure the voltage between terminals A and B by using a voltmeter, from the rear side of the connector.

Specification: 2.5-2.8 V




4. Disconnect the vacuum hose from the manifold absolute pressure sensor.
5. Disconnect the vacuum hose from the intake manifold side of the MAP sensor solenoid valve and connect the vacuum hose to the manifold absolute pressure sensor.
6. Measure the voltage between terminals A and B by using a voltmeter, from the rear side of the connector.

Specification: 1.2-1.6 V

7. Turn off the ignition switch.
8. If not as specified, replace the manifold absolute pressure sensor.
