DTC DETECTION LOGIC

NOTE:
• Conditions for applying the diagnostic procedure to the stored DTCs:

The DTC becomes present during the first 30 seconds after the engine starts.

• In low ambient temperature conditions, diagnostic cannot make difference between a normal long engine

start and abnormal long engine start. So, DTC must be take in account only if customer complains about too
long or impossible engine start not only in cold conditions but also and especially in warm conditions. If cus-
tomer complains only in cold conditions, root cause of the problem could elsewhere like low battery level,
bad fuel specification (too viscous fuel). This DTC could appear after fuel filter too.

• Special notes:

Starting and engine operation difficult or impossible.

1.

Check the continuity between turbocharger boost sensor harness connector and ECM harness connector.

2.

Also check harness for short to ground and short to power.

Is the inspection result normal?

DTC No.

YES

>> GO TO 5.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

5.

CHECK TUBOCHARGER BOOST SENSOR

Refer to

EC-912, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Replace turbocharger boost sensor.

Component Inspection

INFOID:0000000006496589

1.

CHECK TURBOCHARGER BOOST SENSOR-I

1.

Turn ignition switch OFF.

2.

Remove turbocharger boost sensor with its harness connected.

3.

Turn ignition switch ON.

4.

Select “DATA MONITOR” mode with CONSULT-III.

5.

Check “BOOST PRESS” and “ATOMOS PRESS” indication.

If the value is not very close to “ATOMOS PRESS”, maximum pressure difference between “ATOMOS
PRESS” and “BOOST PRESS” with the ignition switch ON (engine stop) =

±

50 mbar?

YES

>> GO TO 2.

NO

>> Replace turbocharger boost sensor.

2.

CHECK TURBOCHARGER BOOST SENSOR-II

1.

Use pump (A) to apply turbocharger boost sensor (1) as shown
in the figure.

2.

Apply a pressure of between 10 kPa (0.100 bar, 0.102 kg/cm

2

,

1.5 psi) - 13 kPa (0.130 bar, 0.133 kg/cm

2

, 1.9 psi) [maximum

pressure to be applied: 13 kPa (0.130 bar, 0.133 kg/cm

2

, 1.9

psi)].

3.

Select “DATA MONITOR” mode with CONSULT-III.

4.

Check “BOOST PRESS” indication with that given by the vac-
uum pump.

If there is no discrepancy?

YES

>> INSPECTION END

NO

>> Replace turbocharger boost sensor.
