1.

CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR

1. Turn ignition switch OFF.

2. Remove EVAP control system pressure sensor with its harness connector connected from EVAP canister.

Always replace O-ring with a new one.

3. Install a vacuum pump to EVAP control system pressure sensor.

4. Turn ignition switch ON and check output voltage between ECM harness connector and ground under the

following conditions.

CAUTION:

• Always calibrate the vacuum pump gauge when using it.
• Do not apply below -93.3 kPa (-0.952 kg/cm

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

Always perform test at a temperature of 5

°C (41°F) or more.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1. Start engine and warm it up to normal operating temperature.

2. Turn ignition switch OFF and wait at least 10 seconds.

3. Turn ignition switch ON.

4. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.

5. Make sure that “FUEL T/TMP SE” indication is more than 0

°C (32°F).

6. Start engine and wait at least 20 seconds.

7. Check 1st trip DTC.

With GST

1. Start engine and warm it up to normal operating temperature.

2. Set voltmeter probes to ECM harness connector terminals as per the following.

3. Make sure that the voltage is less than 4.2 V.

4. Turn ignition switch OFF and wait at least 10 seconds.

5. Start engine and wait at least 20 seconds.
