Nissan Latio Check Engine Light Malaysia
Common check engine codes on the Latio N17: P0300–P0304 misfire (spark plugs or injectors), P0420 catalyst efficiency (downstream O2 sensor or cat), P0740 CVT torque converter lock-up (CVT fluid issue), P0505 idle control (throttle body carbon), P0340 camshaft position sensor. The CVT-related codes require Nissan Consult for detailed diagnosis. Do not ignore a flashing check engine light — a flashing light indicates active misfire that can damage the catalytic converter.

Latio Check Engine Light
- Scan OBD immediately when CEL lights up — do not ignore
- Flashing CEL = active misfire — stop driving, risk of catalytic converter damage
- Steady CEL with normal driving: non-urgent but repair within 1 week
- Common causes: O2 sensor, loose fuel cap (EVAP), misfires, MAF sensor
