(b) Using a 19 mm deep socket wrench, remove the ECT sensor and gasket. 3. INSPECT ECT SENSOR Using an ohmmeter, measure the resistance between the ter- minals. Resistance: Refer to the graph If the resistance is not as specified, replace the ECT sensor. 4. REINSTALL ECT SENSOR (a) Install a new gasket to the ECT sensor. (b) Using a 19 mm deep socket, install the ECT sensor. Torque: 20 N·m (200 kgf·cm, 14 ft·lbf) (c) Connect the ECT sensor connector. 5. REFILL WITH ENGINE COOLANT

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 vacuum hose from the vapor pressure sensor. (c) Connect a voltmeter to terminals PTNK and E2 of the ECM, and measure the output voltage under the following conditions: z Apply vacuum (2.0 kPa, 15 mmHg, 0.59 in.Hg) to the vapor pressure sensor. Voltage: 1.3 – 2.1 V z Release the vacuum from the vapor pressure sen- sor. Voltage: 3.0 – 3.6 V z 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 vacuum hose to the vapor pressure sen- sor.
