2013 Nissan Murano Check Engine Light in Mesa, AZ

An OBD-II trouble code stored in the ECU identifies the affected system—often EVAP, oxygen sensor, MAF, ignition/misfire, or catalytic converter.

Your Murano’s light is a signal that the engine or emissions system detected a fault. Our Mesa team retrieves codes and freeze-frame data to see what happened and under what conditions. We then confirm the root cause with targeted tests instead of guessing. You can schedule service or check service specials online.

• OBD-II codes point to systems (e.g., P0455 EVAP, P0420 catalyst)
• Freeze-frame data shows RPM, temp, and load at the moment of the fault
• Verification testing prevents parts swapping and repeat visits

Common codes include P0300 (misfire), P0420 (catalyst efficiency), P0455 (EVAP large leak), P0101 (MAF performance), and P0138/P0139 (O2 sensor).

These faults cover ignition, fuel/air metering, evaporative emissions, and catalytic converter efficiency—systems frequently seen on high-mileage crossovers in Arizona’s heat. Our diagnostics separate a loose gas cap from a failing sensor or converter so you only repair what’s needed. Book a diagnostic appointment in Mesa today.

• P0455 may be as simple as a loose or failing gas cap
• P0300 misfires can damage the catalytic converter if ignored
• P0101 often traces to a dirty/failed MAF or intake air leaks

A steady light means drive cautiously to service, but a flashing light indicates an active misfire—stop driving to avoid catalytic converter damage.

If the light is steady and the Murano runs normally, reduce load and schedule diagnostics soon. If it’s flashing, continued driving can overheat the converter and increase repair costs. Our Mesa service team can evaluate symptoms quickly and provide a written estimate before any work.

• Flashing MIL = misfire severe enough to harm the catalyst
• Steady MIL = non-urgent, but diagnose promptly to prevent escalation

A parts store reads generic OBD-II codes, while our Nissan dealership uses factory CONSULT scan tools, Nissan technical data, and isolation testing to find the root cause.

Codes describe what failed monitoring—not necessarily which part is bad. We analyze freeze-frame data, perform pinpoint tests, and confirm the fix before recommending repair. That added accuracy helps prevent unnecessary parts and repeat visits for Phoenix East Valley drivers.

• Factory CONSULT access and Nissan service bulletins
• System tests (smoke/EVAP, fuel trim analysis, misfire counters)
• Written estimate before any repair is performed

No—clearing the light resets OBD-II readiness monitors, and your Murano will typically fail Arizona emissions until monitors complete.

Inspection stations check for stored codes and readiness status. Recently cleared systems show “Not Ready,” which is a failure even if the light is off. The correct approach is to repair the fault, verify all monitors set to “Ready,” and confirm no pending codes. Need help completing drive cycles? Schedule service in Mesa.

• Readiness monitors must be “Ready” for a pass
• Pending codes can still trigger a failure
• We verify monitors and road-test after repairs

It means an OBD-II code and freeze-frame data were set—pointing to a specific system like EVAP, fuel/air, or ignition that needs verification testing.

Our Mesa Nissan service advisors translate codes into clear next steps and outline diagnostic time before any repair. You’ll receive a written estimate and options once we isolate the root cause. Check service specials or schedule your appointment online.

• Code retrieval plus freeze-frame analysis
• Targeted tests confirm what failed and why
• Transparent estimate and repair plan

We begin with a full OBD-II scan on your 2013 Nissan Murano using Nissan CONSULT, recording fault codes and freeze-frame data to understand the exact conditions present when the fault occurred. A visual inspection follows to check connectors, vacuum lines, intake ducting, and obvious issues. Next, we perform isolation testing tailored to the code set—this can include smoke testing the EVAP system, fuel-trim analysis, MAF and O2 sensor signal checks, or ignition and compression testing for misfires. Before any repair, you receive a written estimate and explanation of findings. Warranty work typically requires service at a certified facility to protect coverage. Ready to move forward?

Several fault patterns are frequently seen on the 2013 Nissan Murano. Code P0455 often indicates a large EVAP leak, sometimes traced to a loose or deteriorated gas cap; ignoring it can keep the MIL on and cause an emissions test failure. P0300 marks random misfires that, if left unresolved, can overheat and damage the catalytic converter, raising repair costs. P0420 signals reduced catalyst efficiency, which may stem from underlying misfires or exhaust leaks. P0101 points to MAF performance issues, often from contamination or unmetered air. P0138/P0139 indicate oxygen sensor circuit faults. Bring your 2013 Nissan Murano to Larry H. Miller Nissan Mesa in Mesa for an accurate diagnosis — schedule service.

LHM Nissan Mesa serves the Phoenix East Valley and Greater Phoenix metro area—including Mesa, Tempe, Scottsdale, Chandler, Gilbert, and Phoenix.
