(c) Connect a voltmeter to terminals PTNK and E2 of the ECM, and measure the output voltage under the following conditions:

(1) Apply vacuum (2.0 kPa, 15 mmHg, 0.59 in.Hg) to the vapor pressure sensor.

Voltage: 1.3 - 2.1 V 

(2) Release the vacuum from the vapor pressure sensor.

Voltage: 3.0 - 3.6 V 

(3) Apply pressure (1.5 kPa, 15 gf/sq.cm, 0.22 psi) to the vapor pressure sensor.

Voltage: 4.2 - 4.8 V 

(d) Reconnect the EVAP hose to the vapor pressure sensor.
