2012 Nissan Murano CrossCabriolet Check Engine Light Codes

Common codes for the 2012 Nissan Murano CrossCabriolet in Mesa, AZ often point to oxygen sensors (P0130–P0167), catalytic converter issues (P0420), evap leaks (P0440–P0455), and charging/battery faults that throw codes tied to alternator performance. Ignoring these codes can escalate costs: a faulty oxygen sensor left unaddressed can reduce fuel efficiency and damage the catalytic converter, turning a modest sensor replacement into a $1,000+ repair. An undiagnosed charging issue can degrade the battery and strain starter/alternator components, producing repeated breakdowns and higher long-term expense. At Larry H. Miller Nissan Mesa, our certified Nissan technicians use OEM diagnostic flows and genuine parts to identify the correct repair path and explain immediate and long-term savings.
