2014 Nissan 370Z Check Engine Light Reset

Resetting the check engine light on a 2014 Nissan 370Z might seem simple, but a reset without proper diagnosis can hide a recurring issue and lead to larger repairs later. At Larry H. Miller Nissan Mesa in Mesa, AZ, our factory-trained technicians first perform a complete OBD-II scan and systems check to identify any stored codes or pending faults. If the issue is minor and resolved — for example, a tightened gas cap or a cleared misfire after a spark plug replacement — we’ll reset the light and document the repair with a clear explanation of steps taken and recommended follow-ups. If codes indicate more serious problems, we’ll present OEM parts options, transparent pricing, and warranty information so you understand both immediate costs and long-term savings.

2014 Nissan 370Z Check Engine Light Codes

Common check engine light codes for a 2014 Nissan 370Z include P0171/P0172 (fuel trim issues), P0300 series (misfires), P0420 (catalyst efficiency), and oxygen sensor codes. Left unchecked, these can reduce fuel economy, damage catalytic converters, increase emissions, and lead to costly repairs. For instance, ignoring misfires can ruin catalytic converters — a repair that often costs significantly more than addressing the originating ignition or fuel problem. At Larry H.
