Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
On-Vehicle Inspection
- INSPECT IGNITION COIL (WITH IGNITER) AND SPARK TEST
Check that the spark occurs.
- Remove the ignition coils (with igniter). (See REMOVAL )
- Using a 16 mm (0.63 in.) plug wrench, remove the spark plugs.
- Install the spark plugs to each ignition coils (with igniter), and connect the ignition coil connectors.
- Disconnect the 4 injector connectors.
- Ground the spark plugs.
- Check if spark occurs while engine is being cranked.NOTE: To prevent gasoline from being injected from injectors during this test, crank the engine for no more than 5 -10 seconds at time.
If the spark does not occur, do the test as follows:
- Using a 16 mm (0.63 in.) plug wrench, install the spark plugs.
Torque: 18 N.m (184 kgf.cm, 13 ft.lbf)
- Install the ignition coils (with igniter).
- (See INSTALLATION )
- INSPECT SPARK PLUGS
- Remove the ignition coils (with igniter).
- (See REMOVAL )
- Using a 16 mm (0.63 in.) plug wrench, remove the spark plugs.
- Clean the spark plugs.
If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner.
- Air pressure: Below 588 kPa (6 kgf/cm 2 , 85 psi)
- Duration: 20 seconds or less
HINT:
If there are traces of oil, remove it with gasoline before using the spark plug cleaner.
- Check the spark plug for thread damage and insulator damage.
If abnormal, replace the spark plug.
Recommended spark plug:
RECOMMENDED SPARK PLUG 1ZZ-FEDENSO made SK16R11 NGK made IFR5A11 RECOMMENDED SPARK PLUG 2ZZ-GEDENSO made SK20R11 NGK made IFR6A11 - Adjust electrode gap.
- Carefully bend the outer electrode to obtain the correct electrode gap.
- Electrode gap: 1.1 mm (0.043 in.)
- Using a 16 mm (0.63 in.) plug wrench, install the spark plugs.
- Torque: 18 N.m (184 kgf.cm, 13 ft.lbf)
- Install the ignition coils (with igniter).
- (See INSTALLATION )
- Remove the ignition coils (with igniter).
- INSPECT CAMSHAFT POSITION SENSOR
- Disconnect the camshaft position sensor connector.
- Using an ohmmeter, measure the resistance between terminals.RESISTANCE BETWEEN TERMINALS
Cold 835 - 1,400 Ω Hot1 1,060 - 1,645 Ω If the resistance is not as specified, replace the camshaft position sensor.
- Connect the camshaft position sensor connector.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
