1996 RAV4 (RM447U)
INSPECTION
1. INSPECT POWER SOURCE VOLTAGE OF VAPOR
PRESSURE SENSOR
(a) Disconnect the vapor pressure sensor connector.
(b) Turn the ignition switch ON.
(c) Using a voltmeter, measure the voltage between connec-
tor terminals VC and E2 of the wiring harness side.
Voltage: 4.5 − 5.5 V
(d) Turn the ignition switch to LOCK.
(e) Reconnect the vapor pressure sensor connector.
2. INSPECT POWER OUTPUT OF VAPOR PRESSURE
SENSOR
(a) Turn the ignition switch ON.
(b) Disconnect the EVAP hose from the vapor pressure sen-
sor.
(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 sen-
sor.
Voltage: 3.0 − 3.6 V
(3) Apply pressure (1.5 kPa, 15 gf/cm
2, 0.22 psi) to the
vapor pressure sensor.
Voltage: 4.2 − 4.8 V
(d) Reconnect the EVAP hose to the vapor pressure sensor.

INSPECTION
1. 4WD:
REMOVE ENGINE AND TRANSAXLE ASSEMBLY (See
page EM−68)
2. REMOVE KNOCK SENSOR
(a) Disconnect the knock sensor connector.
(b) Using SST, remove the knock sensor.
SST 09816−30010
Torque: 44 N·m (450 kgf·cm, 33 ft·lbf)
3. INSPECT KNOCK SENSOR
Using an ohmmeter, check that there is no continuity between
the terminal and body.
If there is continuity, replace the sensor.
4. REINSTALL KNOCK SENSOR
Installation is in the reverse order of removal.
5. 4WD:
REINSTALL ENGINE AND TRANSAXLE ASSEMBLY
