Diagnostic Test
- CHECK COMPONENT FUNCTION-1
With CONSULT
- Turn ignition switch ON.
- On CONSULT screen, select "ENGINE" >> "ACTIVE TEST" >> "BOOST PRESSURE CONTROL".
- Start the engine and let it idle.
- Check that the value of "BOOST PRES POSITNR DUTY" is between 87% and 100%.
Is the inspection result normal?
YES
GO TO STEP 7 .
NO
GO TO STEP 2 .
- CHECK FUSE
- Turn ignition switch OFF.
- Pull out #214 (10A) fuse.
- Check that the fuse is not fusing.
Is the inspection result normal?
YES
GO TO STEP 3 .
NO
Replace the fuse after repairing the applicable circuit.
- CHECK BOOST PRESSURE CONTROL VACUUM TRANSDUCER POWER SUPPLY
- Reinsert the fuse which pulled out.
- Disconnect boost pressure control vacuum transducer harness connector.
- Turn ignition switch ON.
- Check the voltage between boost pressure control vacuum transducer harness connector and ground.
+ - Voltage Boost pressure control vacuum transducer Connector Terminal F168 1 Ground Battery voltage
Is the inspection result normal?
YES
GO TO STEP 5 .
NO
GO TO STEP 4 .
- CHECK BOOST PRESSURE CONTROL VACUUM TRANSDUCER POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Pull out #214 (10 A) fuse.
- Check the continuity between boost pressure control vacuum transducer harness connector and fuse terminal.
+ - Continuity Boost pressure control vacuum transducer Connector Terminal F168 1 #214 fuse terminal Existed - Also check harness for short to ground.
Is the inspection result normal?
YES
Check intermittent incident. Refer to INTERMITTENT INCIDENT .
NO
Repair or replace error-detected parts.
- CHECK BOOST PRESSURE CONTROL VACUUM TRANSDUCER
Check boost pressure control vacuum transducer. Refer to COMPONENT INSPECTION (BOOST PRESSURE CONTROL VACUUM TRANSDUCER) .
Is the inspection result normal?
YES
GO TO STEP 6 .
NO
Replace boost pressure control vacuum transducer.
- CHECK BOOST PRESSURE CONTROL VACUUM TRANSDUCER CONTROL CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between ECM harness connector and boost pressure control vacuum transducer harness connector.
+ - Continuity ECM Boost pressure control vacuum transducer Connector Terminal Connector Terminal F149 51 F168 2 Existed - Also check harness for short to ground.
Is the inspection result normal?
YES
INSPECTION END
NO
Repair or replace error-detected parts.
- CHECK COMPONENT FUNCTION-2
With CONSULT
- Set the vehicle to the following conditions.
Item Condition Engine speed Idle Engine coolant temperature Less than 75°C (167°F) Electrical load OFF - Perform Active Test.
- Check that the turbocharger control rod moves smoothly by visually check.CAUTION:
Never operate the control rod by hand.
Is the inspection result normal?
YES
GO TO STEP 9 .
NO
GO TO STEP 8 .
- Set the vehicle to the following conditions.
- CHECK VACUUM PRESSURE
- Turn ignition switch OFF.
- Disconnect vacuum hose at boost pressure control vacuum transducer.
- Connect vacuum tester.
- Start the engine and let it idle.
- Check that the vacuum pressure is more than - 75 kPa (- 750 mbar, - 0.765 kg/cm2 , - 10.9 psi).
Is the inspection result normal?
YES
GO TO STEP 9 .
NO
Check vacuum line leakage, or vacuum pump performance.
- CHECK COMPONENT
Check the following.
- Pressure sensor upstream of throttle valve (foreign matter is caught.)
- Turbocharger (obstructed movement)
- Exhaust gas pressure
- Charge air leakage
- Divert air switchover valve diaphragm
