Check Engine Light Flashing

The sight of a flashing check engine light in your 2015 Nissan Murano demands immediate attention because it typically indicates an active misfire, which can allow unburned fuel into the exhaust stream and rapidly damage the catalytic converter. Left untreated, what might start as a relatively affordable ignition or fuel-system repair can escalate into a costly emissions system replacement that affects performance, increases fuel consumption, and risks failed emissions testing. At Larry H. Miller Nissan Mesa in Mesa, AZ, our certified technicians prioritize safety and long-term value: we use OEM diagnostic tools to pinpoint the cause, recommend targeted repairs, and explain how timely intervention saves you money over the life of the vehicle. We offer service financing to spread the cost and have regular service specials to reduce out-of-pocket expense. If your check engine light is flashing, do not drive the vehicle hard; contact us and schedule service immediately so we can assess whether towing or in-service repairs are needed to protect your Murano and your wallet.

2015 Nissan Murano Check Engine Light Codes

Understanding common diagnostic trouble codes for the 2015 Nissan Murano helps owners make informed decisions and prevents minor issues from becoming major repairs. Codes like P0300 (random/multiple misfires) often stem from spark plugs, ignition coils, or fuel delivery problems — ignoring them can ruin catalytic converters and cost hundreds to thousands in downstream repairs. P0420 (catalyst system efficiency below threshold) may point to a failed catalytic converter or an upstream sensor like an oxygen sensor; delaying repair raises emissions and fuel costs. P0171 (system too lean) and P0442 (EVAP small leak) can reduce mileage and trigger recurring light resets if not diagnosed properly. At Larry H. Miller Nissan Mesa in Mesa, AZ, our factory-trained technicians use OEM scanners to read and interpret codes correctly, present transparent estimates, and explain immediate and long-term savings of addressing the root cause. We also honor warranties for covered repairs when performed here and provide service financing so you can repair now and pay over time; check our service specials and schedule appointment online for fast, trustworthy service.
