Item 22: Crank angle sensor

Q: Is the check result normal?

YES: Go to Step 10

.
NO: Check crank angle sensor system (Refer to Code No. P0335

STEP 10: Check injector for operating sound.

Check injector for operating sound (Refer to ).

Q: Can operating sound be heard?

YES: Go to Step 11

.
NO:

Check the injector system of the defective cylinder.

(Refer to Code No. P0201: No. 1 injector system .)

(Refer to Code No. P0202: No. 2 injector system .)

(Refer to Code No. P0203: No. 3 injector system .)

(Refer to Code No. P0204: No. 4 injector system .)

STEP 11: Check ignition coil spark.

Q: Is the check result normal?

YES: Go to Step 12

.
NO:

Check ignition circuit system (Refer to Inspection Procedure 30)

STEP 12: Fuel pressure measurement.

Fuel pressure measurement (Refer to ).

Q: Is the check result normal?

YES: Go to Step 13

.
NO: Repair.

STEP 13: Replace engine-A/T-ECU

After replacing the engine-A/T-ECU, re-check the trouble symptoms.

Q: Does trouble symptom persist?

YES: Check for foreign matters (water, kerosene, etc.) in fuel and replace if necessary.
NO: Check end.


Inspection Procedure 6: Starting Impossible (Starter Operative but No Initial Combustion)

COMMENT ON TROUBLE SYMPTOM Failure is possibly caused by failed ignition circuit, failed fuel feed or other faults.
PROBABLE CAUSE Failed battery Timing belt broken Failed idle speed control Throttle valve fouled around Failed ignition system Failed fuel system Failed immobilizer system Failed inhibitor-switch Failed engine-A/T-ECU
	DIAGNOSIS PROCEDURE NOTE: ^1 : L.H. drive vehicles ^2 : R.H. drive vehicles

	STEP 1: Check battery voltage. Measure battery voltage at cranking. OK: 8 V or higher Q: Is the check result normal? YES: Go to STEP 2 . NO: Check battery (Refer to GROUP 54 - Battery - On-vehicle Service - Battery Test ).
	STEP 2: Check engine warning lamp for burnt out bulb. Q: Is the check result normal? YES: Go to Step 3 . NO: Check engine-A/T-ECU power supply, engine control relay and ignition switch IG1 system (Refer to Inspection Procedure 24 ).
	STEP 3: MUT-II/III diagnosis code Q: Diagnosis code set? YES: Inspection chart for diagnosis codes (Refer to ) NO: Go to Step 4 .

	STEP 5. Check timing belt for breakage. Engine: Cranking OK: Camshaft rotates. Q: Is the check result normal? YES: Go to Step 6 . NO: Replace timing belt.
	STEP 6. Check throttle body (throttle valve) contamination. Q: Is the check result normal? YES: Go to Step 7 . NO: Clean throttle body (throttle valve portion) (Refer to ).
	STEP 7: MUT-II/III data list Item 18: Cranking signal OK: ON (Ignition switch: ST) OFF (Ignition switch: ON) Q: Is the check result normal? YES: Go to Step 9 . NO: Go to Step 8 .
	STEP 8: Connector check: C-135 engine-A/T-ECU connector
	Q: Is the check result normal? YES: Check intermediate connectors B-19, and repair if necessary. If intermediate connectors are normal, check and repair harness between B-22 (terminal No. 9) inhibitor switch connector and C-135 (terminal No. 51) engine-A/T-ECU connector. Check output line for open/short circuit. NO: Repair.
