– ENGINE (1MZ–FE)
PREPARATION:
(a) Remove the glove compartment (See page SF–73).
(b) Turn the ignition switch ON.
CHECK:
Measure voltage between terminals PTNK and E2 of the ECM
connectors.
(1) Disconnect the vacuum hose from the vapor pres-
sure sensor.
(2) Using the MITYVAC (Hand–Held 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).
OK:
(1) Voltage: 2.9 ∼ 3.7 V
(2) Voltage: 0.5 V or less
OK Go to step 12.
NG Repair or replace harness or connector.
