Check Engine Light Flashing

The check engine light flashing in a 2014 Chrysler 300 signals an active misfire or a condition that can cause immediate engine or emissions damage. A flashing light is more urgent than a steady one: it often means unburned fuel is entering the exhaust stream, which can overheat and damage the catalytic converter and other downstream components. Prompt dealer diagnostics limit repair scope and expense—waiting allows the problem to escalate and can multiply repair costs. At Larry H. Miller Chrysler Jeep Dodge Ram Boise in Boise, ID, our certified technicians use factory-level scan tools to isolate the cause quickly, advise on OEM parts or recommended repairs, and provide a clear cost estimate. We also highlight available service financing so you can address urgent repairs now and pay over time.

Miller Chrysler Jeep Dodge Ram Boise is to perform a complete diagnostic scan, interpret freeze-frame data, and explain the cause and repair options before any reset. Dealer-performed service uses OEM parts, maintains warranty integrity, and ensures accurate software updates when required; warranty-covered work must be done at a certified dealership to remain valid.

2014 Chrysler 300 Check Engine Light Codes

Common check engine light codes for a 2014 Chrysler 300 include P0420 (catalytic converter efficiency), P0300–P0306 (random/multiple cylinder misfires), P0130–P0167 (oxygen sensor range/response), and P0455 (evaporative emission system leak). Left unaddressed, P0300-series misfires can damage pistons and catalytic converters—repair costs escalate from spark plug or coil replacement to full exhaust component replacement. A P0420 diagnosis often leads to catalytic converter replacement if downstream systems are degraded, which is significantly more expensive than early oxygen sensor replacement or minor repairs. At Larry H. Miller Chrysler Jeep Dodge Ram Boise our technicians perform a systematic diagnostic path to identify root causes and present cost-effective alternatives where appropriate. Choosing dealership service frequently reduces total ownership cost through accurate diagnosis, genuine parts, factory-aligned repair procedures, and warranty-backed work.
