Toyota Corolla Repair Manual: Inspection procedure

Hint

:

1 Inspect ecm(vc voltage)

  1. Turn the ignition switch on.
  2.  measure the voltage between the terminals of the e3 ecm connector.

Standard:

2 Inspect ecm(ptnk voltage)

2 Inspect ecm(ptnk voltage)

  1. Turn the ignition switch on.
  2.  measure the voltage between the terminals of the e3 and e6 ecm connectors.
  1.  Disconnect the vacuum hose from the vapor pressure sensor.

Standard (1):

  1. Using the mityvac (handheld vacuum pump), apply a vacuum of 4.0 Kpa (30 mmhg, 1.18 In.Hg) to the vapor pressure sensor.

Notice

: the vacuum applied to the vapor pressure sensor must be less than 66.7 Kpa (500 mmhg, 19.7 In.Hg).

Standard (2):

  1. Reconnect the vacuum hose.

3 Check harness and connector(vapor pressure sensor  ecm)

3 Check harness and connector(vapor pressure sensor ecm)

  1. Disconnect the v4 vapor pressure sensor connector.
  2.  disconnect the e3 and e6 ecm connectors.
  3.  check the resistance between the wire harness side connectors.

Standard (check for open):

Standard (check for short):

Standard (check for short):

  1. Reconnect the ecm connectors.
  2. reconnect the vapor pressure sensor connector.
