c. Connect a voltage to terminals PTNK and E2 of the ECM, and measure the output voltage under the following connectors:

-

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

Voltage: 1.3 - 2.1 V

-

Release the vacuum from the vapor pressure sensor.

Voltage: 3.0 - 3.6 V

-

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

Voltage: 4.2 - 4.8 V

d. Disconnect the vacuum hose to the vapor pressure sensor.
