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
2
, -13.53 psi) or pressure over 101.3 kPa (1.033 kg/
cm
2
, 14.69 psi).
Is the inspection result normal?
YES

1.
CHECK TURBOCHARGER BOOST SENSOR
1. Turn ignition switch OFF.
2. Remove turbocharger boost sensor with its harness connector.
3. Install pressure pump (A) to turbocharger boost sensor (1).
CAUTION:
When insert a pressure pump hose to the sensor, be careful
to the damage of the sensor housing.
4. Turn ignition switch ON.
5. Check the voltage between ECM harness connector terminals
as per the following conditions.
NOTE:
• Always calibrate the pressure pump gauge when using it.
• Inspection should be done at room temperature [10 - 30
°C (50 - 86°F)].

DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-
ing 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:
Before performing the following procedure, confirm that battery voltage is more than 8 V at idle.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
