Diagnosis Procedure
1.CHECK DTC PRIORITY
If DTC P117A is displayed with other DTC, first perform the trouble diagnosis for other DTC.
Is applicable DTC detected?
YES >> Perform diagnosis of applicable. Refer to EC-93, "DTC Index".
NO >> GO TO 2.
2.CHECK FOR INTAKE AIR LEAK
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace error-detected parts.
3.CHECK EXHAUST GAS LEAK
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK FUEL PRESSURE
Is the inspection result normal? YES >> GO TO 5.
NO >> GO TO 10.
5.CHECK MASS AIR FLOW SENSOR
With CONSULT
Check “MASS AIR FLOW” in “DATA MONITOR” mode of “ENGINE” using CONSULT.
For specification, refer to EC-500, "Mass Air Flow Sensor".
With GST
Check mass air flow sensor signal in Service $01 using GST.
For specification, refer to EC-500, "Mass Air Flow Sensor".
Is the inspection result normal? YES >> GO TO 6.
NO >> Check connectors for rusted terminals or loose connections in the mass air flow sensor circuit or grounds. Refer to EC-199, "Diagnosis Procedure".
6.CHECK FUNCTION OF FUEL INJECTOR-1
With CONSULT
Without CONSULT
Clicking noise should be heard.
Is the inspection result normal? YES >> GO TO 7.
NO >> Perform trouble diagnosis for fuel injector, refer to EC- 464, "Component Function Check".
7.CHECK FUNCTION OF FUEL INJECTOR-2
CAUTION: Perform the following procedure in a place with no combustible objects and good ventilation.
Keep fuel hose and all fuel injectors connected to fuel tube.
Is the inspection result normal? YES >> GO TO 8.
NO >> Replace fuel injector. Refer to EM-40, "Removal and Installation".
8.CHECK FUNCTION OF IGNITION COIL-1
CAUTION: Perform the following steps in a well-ventilated area with no combustibles.
NOTE: CONSULT must not be used to release fuel pressure. It develops again during the following steps, if released by using CONSULT.
Spark should be generated.
CAUTION:
NOTE: When the gap is less than 13 mm (0.52 in), a the spark might be generated even if the coil is malfunctioning. Is the inspection result normal? YES >> GO TO 9.
NO >> GO TO 11.
9.CHECK COMPRESSION PRESSURE
Check compression pressure. Refer to EM-22, "Compression pressure".
Is the inspection result normal? YES >> GO TO 14.
NO >> Check pistons, piston rings, valves, valve seats and cylinder head gaskets.
10.DETECT MALFUNCTIONING PART
Check fuel hoses and fuel tubes for clogging.
Is the inspection result normal? YES >> Replace fuel filter and fuel pump assembly. Refer to FL-6, "Removal and Installation".
NO >> Repair or replace error-detected parts.
11.CHECK FUNCTION OF IGNITION COIL-2
Spark should be generated.
Is the inspection result normal? YES >> GO TO 12.
NO >> Check ignition coil, power transistor and their circuits. Refer to EC-470, "Component Function Check".
12.CHECK SPARK PLUG
Check the initial spark plug for fouling, etc.
Is the inspection result normal? YES >> 1. Repair or clean spark plug. Refer to EM-17, "Removal and Installation".
2. GO TO 13.
NO >> Replace spark plug(s) with standard type one(s). For spark plug type, refer to EM-115, "General Specification".
13.CHECK FUNCTION OF IGNITION COIL-3
Spark should be generated.
Is the inspection result normal? YES >> GO TO 14.
NO >> Replace spark plug(s) with standard type one(s). For spark plug type, refer to EM-115, "General Specification".
14.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
