Diagnosis ProcedureINFOID:0000000001162562
1.CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Check ground connection E15. Refer to Ground inspection in GI-58, "
Circuit Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK TUBOCHARGER BOOST SENSOR SUPPLY CIRCUIT
1. Disconnect turbocharger boost sensor harness connector.
2. Turn ignition switch ON.
3. Check the voltage between turbocharger boost sensor connector and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK TUBOCHARGER BOOST SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
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?
YES >> GO TO 4.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK TUBOCHARGER BOOST SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between turbocharger boost sensor harness connector and ECM harness connector.

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 can.t 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 customer
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.
Diagnosis ProcedureINFOID:0000000001162565
1.CHECK LOW PRESSURE FUEL SUPPLY SYSTEM
Refer to EC-1043, "
BASIC INSPECTION : Special Repair Requirement (TEST 1: Low Pressure Fuel Supply
System Check)".
Is the inspection result normal?
OK >> GO TO 2.
NG >> Replace or replace. Then GO TO 7.
2.CHECK INTERNAL FUEL TRANSFER PUMP
Refer to EC-1044, "
BASIC INSPECTION : Special Repair Requirement (TEST 2: Internal Fuel Transfer Pump
Check)".
Is the inspection result normal?
OK >> GO TO 3.
NG >> Replace or replace. Then GO TO 7.
3.CHECK HIGH PRESSURE SUPPLY PUMP (PRESSURE CONTROL VALVE)
Refer to EC-1044, "
BASIC INSPECTION : Special Repair Requirement [TEST 3: High Pressure Supply Pump
(Pressure Control Valve) Check]".
Is the inspection result normal?
OK >> GO TO 4.
NG >> Replace or replace. Then GO TO 7.
4.CHECK HIGH PRESSURE SUPPLY PUMP (VOLUMETRIC CONTROL VALVE)
Refer to EC-1045, "
BASIC INSPECTION : Special Repair Requirement [TEST 4: High Pressure Supply Pump
(Volumetric Control Valve) Check]".
Is the inspection result normal?
OK >> GO TO 5.
DTC No. Trouble diagnosis name Possible cause
