On-Vehicle Inspection
- INSPECT IGNITION COIL ASSY AND SPARK PLUG
- Check the DTCs (see DTC CHECK/CLEAR
).NOTE: If a DTC is present, perform troubleshooting in accordance with the procedure for that DTC.
- Check that sparks occur.
- Remove the circuit opening relay (see ON-VEHICLE INSPECTION ).
- Remove the V-bank cover (see REPLACEMENT ).
- Remove the air cleaner (see REPLACEMENT ).
- Disconnect the ventilation hose.
- Remove the 6 ignition coils.
- Using a 16 mm spark plug wrench, remove the 6 spark plugs.
- Install each spark plug into an ignition coil, then connect the ignition coil connectors.
- Ground the spark plugs.
- Check that sparks occur at each spark plug while the engine is being cranked.
NOTE:- Be sure to ground the spark plugs when checking.
- Replace the ignition coil if it has been dropped or subjected to any other impact.
- Do not crank the engine for more than 2 seconds.
If sparks do not occur, perform the following procedure.
- Check the DTCs (see DTC CHECK/CLEAR
).
- SPARK TEST
- NG: GO TO NEXT STEP
- CHECK CONNECTION OF IGNITION COIL CONNECTOR
- NG: CONNECT SECURELY
- OK: Go To Next Step.
- REPLACE IT WITH FUNCTIONING IGNITION COIL AND PERFORM SPARK TEST AGAIN
- OK: REPLACE IGNITION COIL ASSY (See REPLACEMENT )
- NG: GO TO NEXT STEP
- CHECK WIRE HARNESS AND CONNECTOR (POWER SUPPLY)
- Disconnect the ignition coil connector.
- Turn the ignition switch to ON.
- Using a voltmeter, measure the voltage between the terminals.
IGNITION COIL (POWER SUPPLY) SPECIFIED CONDITIONTester Connection Specified Condition 1 (+B) - 4 (GND) 9.0 to 14 V - NG: CHECK WIRE HARNESS AND CONNECTOR (BETWEEN POWER SWITCH AND IGNITION COIL ASSY)
- OK: Go To Next Step.
- INSPECT CRANKSHAFT POSITION SENSOR
(See
INSPECTION )
- NG: REPLACE CRANKSHAFT POSITION SENSOR (See REPLACEMENT )
- OK: Go To Next Step.
- CHECK IGT SIGNAL FROM ECM (See DTC P0351 IGNITION COIL "A" PRIMARY/SECONDARY CIRCUIT, DTC P0352 IGNITION COIL "B" PRIMARY/SECONDARY CIRCUIT, DTC P0353 IGNITION COIL "C" PRIMARY/SECONDARY CIRCUIT, DTC P0354 IGNITION COIL "D" PRIMARY/SECONDARY CIRCUIT, DTC P0355 IGNITION COIL "E" PRIMARY/SECONDARY CIRCUIT, DTC P0356 IGNITION COIL "F" PRIMARY/SECONDARY CIRCUIT )
- NG: REPLACE ECM (See REPLACEMENT )
- OK: REPAIR WIRE HARNESS AND CONNECTOR (BETWEEN IGNITION COIL ASSY AND IGNITION SWITCH)
