6-1-46 ENGINE GENERAL INFORMATION AND DIAGNOSIS (G13/G16 ENGINE WITH WU TWC)
1. MAP sensor
2. 1.5 V battery (4.5 V in total)
3. Vacuum pump
4. Digital type voltmeter
MAP SENSOR INDIVIDUAL CHECK
1) Disconnect coupler from MAP sensor.
2) Remove MAP sensor.
3) Arrange 3 new 1.5 V batteries in series (check that total voltage
is 4.5 – 5.0 V) and connect its positive terminal to "Vin" terminal
of sensor and negative terminal to "Ground" terminal. Then
check voltage between "Vout" and "Ground".
Also, check if voltage reduces when vacuum is applied up to
400 mmHg by using vacuum pump.
Output voltage (Vin voltage 4.5 – 5.5 V, ambient temp.
20 – 30_C, 68 – 86_F)
