2021 Nissan Murano Check Engine Light in Mesa, AZ

OBD-II trouble codes stored in your 2021 Nissan Murano identify the affected system.

Your SUVs engine computer turns the light on when it sees a fault in systems like emissions, ignition, fuel, or sensors. The code points to the system, not automatically the failed part, so proper testing matters. Our Mesa service team reads codes, reviews freeze-frame data, and performs pinpoint tests to confirm the cause before repair.

• Possible minor causes: loose or worn gas cap triggering an EVAP code
• Serious causes: misfire or catalytic converter efficiency faults
• Schedule online: schedule service

The most common causes are O2 sensor faults, EVAP leaks (including gas cap issues), MAF sensor problems, catalytic converter efficiency, or engine misfire.

These categories cover the majority of check engine concerns we see on the 3.5L V6 Murano in the Phoenix East Valley. Each code can have multiple root causes, so component testing is essential before replacing parts. Our Nissan-certified team in Mesa confirms the fault and provides a clear estimate.

On the 2021 Nissan Murano, you may encounter codes such as EVAP system leaks (e.g., P0442/P0455), oxygen/air-fuel sensor performance (P0138/P0158 variants), mass air flow correlation (P0101), catalytic converter efficiency (P0420/P0430), or cylinder misfire (P0300-P0306). Each code points to a system, not a guaranteed failed part; ignoring them can lead to poor fuel economy, rough running, or damage. For example, prolonged misfire can overheat the catalytic converter, turning a minor fix into a major expense. Small EVAP leaks can trigger failed emissions tests until repaired and verified.
