It means the powertrain control module detected a fault and stored an OBD‑II trouble code.

That code identifies the affected system—such as EVAP, oxygen sensors, catalytic converter efficiency, airflow, or misfire. The light can reflect something minor (like a loose gas cap) or a condition that risks damage if ignored. Our technicians read the code, review freeze-frame data, and test the suspected circuit or component to verify the real cause.

• Pinpoint testing to verify
• Clear estimate and options

Frequent causes include O2 sensor faults, EVAP leaks, MAF sensor issues, catalytic converter efficiency, and engine misfires.

Your Durango’s 3.6L V6 and flex‑fuel capability can reveal different fuel-trim behaviors, so verification matters. A loose gas cap can set EVAP codes; aging sensors or ignition parts can trigger efficiency or misfire alerts. We isolate the root cause with factory diagnostics to prevent parts swapping and ensure a lasting fix.

• Scan + smoke test for EVAP
• Sensor and wiring checks
• Ignition and fuel tests

A steady light means drive cautiously to service; a flashing light means stop driving to avoid catalytic converter damage.

If drivability feels normal and the light is steady, reduce load and head to our Tucson location for diagnosis. A flashing light, rough running, or fuel smell suggests a misfire that can overheat the catalyst quickly. To protect your engine and emissions system, schedule a prompt evaluation.

• Flashing = severe misfire
• Steady = service soon

Common codes on the 2013 Dodge Durango include P0442 (small EVAP leak), which often points to a loose gas cap or a minor vapor leak; P0300/P030X (random/single-cylinder misfire), which can overheat and damage catalytic converters if ignored; P0420 (catalyst efficiency below threshold), frequently a downstream effect of misfires or sensor faults; P0101 (MAF performance), which can skew fuel trims; and P0133 (O2 sensor slow response), indicating an aging sensor or wiring concern. Driving with unresolved faults can reduce fuel economy, trigger limp behavior, and lead to costlier repairs over time—especially catalyst replacement. Bring your 2013 Dodge Durango to Larry H.
