2014 Nissan Pathfinder Check Engine Light Codes

The most frequent check engine codes for a 2014 Nissan Pathfinder range from P0442 (evaporative emission small leak) and P0135 (O2 sensor heater circuit) to P0420 (catalyst system efficiency) and hybrid-related battery or inverter codes on hybrid models. Ignoring each code carries a cost: an evap leak like P0442 can reduce fuel efficiency and lead to emissions test failure; a faulty O2 sensor (P0135) can cause poor fuel economy and damage the catalytic converter, which is expensive to replace; P0420 left unaddressed often results in progressive catalytic failure and higher emissions. For hybrid Pathfinders, battery or inverter codes can reduce regenerative braking and overall range, and delaying service increases the chance of larger battery module replacement. At Larry H. Miller Nissan Mesa in Mesa, AZ our certified technicians diagnose these codes with OEM-grade tools, supply clear estimates, and explain the immediate and lifetime savings from correct OEM repairs. We combine quick turnarounds, factory parts, and warranty-backed work — you can also ask about service financing or view our service specials to save.

2014 Nissan Pathfinder Check Engine Light Reset

Resetting a check engine light on a 2014 Nissan Pathfinder may be as simple as clearing stored trouble codes, but a proper reset also requires resolving the underlying issue and completing readiness tests so the light doesn’t return.
