Check Engine Light Flashing

We combine OEM parts, precise factory procedures, and transparent estimates so you know exactly what’s required.

2012 Nissan Versa Check Engine Light Codes

Common codes for a 2012 Nissan Versa include P0420 (catalyst system efficiency low), P0171/P0174 (fuel trim lean), P0300–P0304 (random/multiple cylinder misfires), and P0456 (small EVAP leak). Left unaddressed, each can escalate costs: a persistent P0420 can indicate catalytic converter failure (thousands in parts and labor), misfire codes can damage the converter and pistons, and EVAP leaks can lead to failed emissions tests and repeated check-engine resets. At Larry H. Miller Nissan Mesa we diagnose these codes with factory-grade scanners and explain repair options clearly. Our Mesa service center uses OEM components that preserve vehicle reliability and resale value, and technicians follow Nissan procedures to ensure long-term performance. We emphasize immediate and long-term savings—accurate diagnostics prevent unnecessary parts replacement and avoid repeated labor. To protect your warranty and keep repairs efficient, trust our certified team and schedule service today, and review available service specials before you arrive.

2012 Nissan Versa Check Engine Light Reset

Resetting the check engine light on a 2012 Nissan Versa can be done with a scan tool but doing so without resolving the underlying issue only masks symptoms and risks further damage. At Larry H.

This process protects your vehicle’s health and helps maintain warranty coverage—repairs covered under warranty must be performed at a certified dealership.
