• Schedule service: secure your time slot

It means the engine computer stored an OBD‑II fault code identifying a system that needs attention.

The light can be triggered by minor issues—like a loose gas cap—or more serious faults such as misfires, sensor failures, or catalytic converter efficiency problems. In Arizona’s heat, EVAP and intake air metering concerns are common. Our Mesa team reads the code, reviews freeze-frame data, and tests the likely cause on your 2023 Nissan Maxima before recommending repairs.

• Steady light: schedule service; flashing light: stop driving
• OBD-II pinpoints systems (fuel, ignition, emissions), not exact parts
• Book now: schedule a diagnostic

The most common causes include O2 sensor faults, EVAP leaks (often a loose gas cap), MAF issues, misfires, and catalytic converter efficiency.

These issues are typical on midsize sedans like the 2023 Nissan Maxima, especially with desert heat and large temperature swings. We confirm the root cause with scan data, smoke testing (for EVAP), and pinpoint electrical tests to avoid unnecessary parts replacement. Addressing problems early helps protect fuel economy and emissions components.

• Typical codes: P0171 (lean), P0420 (catalyst), P0455 (EVAP leak)
• Symptoms: rough idle, poor MPG, sulfur smell, hard starts
• Get a definitive diagnosis: schedule now

A steady light means drive cautiously to our Mesa service center; a flashing light means stop driving to avoid catalytic converter damage from a severe misfire.

Continuing to drive with a flashing light can overheat the converter and increase repair costs. If the light is steady and the car drives normally, schedule the earliest available appointment to prevent minor issues from escalating—especially in hot Arizona conditions.

• Flashing light: arrange a tow; avoid highway speeds and heavy load
• Steady light: reduce hard acceleration until diagnosed
• Book Mesa service: schedule today

Several OBD-II codes commonly illuminate the check engine light on midsize sedans like the 2023 Nissan Maxima. P0171 (system too lean) often traces to unmetered air or fuel delivery issues; ignoring it can lead to drivability problems and poor fuel economy. P0420 (catalyst efficiency) may indicate a failing converter or upstream faults—driving too long with misfires can overheat and damage the converter. P0300/P0301–P0306 (misfire) should be addressed promptly to protect the catalytic converter and avoid rough running. P0455 or P0442 (EVAP leaks) can stem from a loose gas cap or a system leak, affecting emissions readiness. P0101 (MAF performance) can reduce power and MPG if uncorrected.
