On-Vehicle Inspection
NOTE:
"Cold" and "Hot" in this section mean the temperature of the coils themselves. "Cold" is from -10°C (14°F) to 50°C (122°F) and "Hot" is from 50°C (122°F) to 100°C (212°F).
- INSPECT IGNITION COIL WITH IGNITER AND PERFORM SPARK TEST
- Check for DTCs.NOTE: If any DTC is present, perform troubleshooting in accordance with the procedures for that DTC.
- Check that spark occurs.
- Set the vehicle to inspection mode. (See Step No. 5 under REPAIR INSTRUCTION )
- Warm up and stop the engine.
- Remove the intake air surge tank. (See
step 20 in REMOVAL
)NOTE: If the throttle body connector is disconnected because the DTC is detected in inspection, always reconnect it.
- Disconnect the 6 injector connectors.
- Remove the ignition coils with igniter.NOTE: If the ignition coil assembly connector is disconnected because the DTC is detected in inspection, always reconnect it.
- Using a 16 mm (0.63 in.) plug wrench, remove the spark plugs.
- Install the spark plugs to each ignition coil with igniter.
- Ground the spark plugs.
- Connect the intelligent tester (with CAN VIM) to the DLC3.NOTE: Check the fully charged battery to indicate HV battery voltage in ECU data monitor.
- Enter ACTIVE TEST MODE on the intelligent tester.
- Check if a spark occurs at each spark plug while the engine is being cranked.NOTE:
- Be sure to ground the spark plug when checking.
- Replace the ignition coil if physical impact is applied to it.
- Do not crank the engine for more than 2 seconds.
- Spark test flow chart.
- Check that the wire harness side connector of the ignition coil with igniter is securely connected.
Result
SPARK TEST FLOW CHART - SECURELY CONNECTEDResult Proceed to NG Connect securely OK Go to step 2 - Perform spark test on each ignition coil with igniter.
- Replace the ignition coil with igniter with a normal one.
- Perform spark test again.
Result
SPARK TEST FLOW CHART - IGNITION COIL WITH IGNITERResult Proceed to OK Replace ignition coil with igniter NG Go to step 3 - Check the power supply to ignition coil with igniter.
- Turn the ignition switch to the ON position.
- Check that battery voltage is applied to the ignition coil positive (+) terminal.
Result
SPARK TEST FLOW CHART - POWER TO IGNITION COIL WITH IGNITERResult Proceed to NG Check wiring between ignition switch and ignition coil with igniter OK Go to step 4 - Check the VVT sensor. (See VVT SENSOR
)
- Measure the resistance according to the value(s) in the table below.
Standard resistance
VVT SENSOR (1 OF 2)Temperature Specified Condition Cold 835 to 1,400 Ω Hot 1,060 to 1,645 Ω Result
VVT SENSOR (2 OF 2)Result Proceed to NG Replace VVT sensor OK Go to step 5
- Measure the resistance according to the value(s) in the table below.
- Check the crankshaft position sensor. (See
REMOVAL
)
- Measure the resistance according to the value(s) in the table below.
Standard resistance
CRANKSHAFT POSITION SENSOR (1 OF 2)Temperature Specified Condition Cold 1,630 to 2,740 Ω Hot 2,065 to 3,225 Ω Result
CRANKSHAFT POSITION SENSOR (2 OF 2)Result Proceed to NG Replace crankshaft position sensor OK Go to step 6
- Measure the resistance according to the value(s) in the table below.
- Check the IGT signal from the 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
)
Result
IGT SIGNAL FROM ECMResult Proceed to NG Check ECM OK Repair wiring between ignition coil and ECM
- Check that the wire harness side connector of the ignition coil with igniter is securely connected.
- Using a 16 mm (0.63 in.) plug wrench, install the spark plugs.
Torque: 25 N*m (250 kgf*cm, 18 ft.*lbf)
- Install the ignition coil with igniter.
Torque: 8.0 N*m (82 kgf*cm, 71 in.*lbf)
- Install the intake air surge tank. (See step 7 in INSTALLATION
)NOTE: After performing all the procedures, be sure to clear DTCs stored in the memory. Then, check that the normal system code is output.
- Check for DTCs.
