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.
Ignition System: Inspection
- INSPECT SPARK PLUG
- Clean the spark plugs.
If the electrode has the traces of wet carbon, clean the electrode with a spark plug cleaner, then dry it.
Air pressure: Below 588 kPa (6 kg/cm 2 , 85 psi)
Duration: 20 seconds or less
- Check the spark plug for any damage on its thread and insulator.
If there is damage, replace the spark plug.
Recommended spark plug:
RECOMMENDED SPARK PLUGDENSO made K16R-U NGK made BKR5EYA - Inspect the electrode gap.
Electrode gap: 0.7 to 0.8 mm (0.028 to 0.031 in.)
- Clean the spark plugs.
- INSPECT CAMSHAFT POSITION SENSOR
- Using an ohmmeter, measure the resistance between the terminals.
RESISTANCE:
1630 to 2740 Ω at cold
2065 to 3225 Ω at hot
NOTE: "Cold" and "Hot" 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).
- Using an ohmmeter, measure the resistance between the terminals.
- INSPECT CRANKSHAFT POSITION SENSOR
- Using an ohmmeter, measure the resistance between the terminals.
RESISTANCE:
985 to 1600 Ω at cold
1265 to 1890 Ω at hot
NOTE: "Cold" and "Hot" 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).

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.
