2017 Ford Taurus Check Engine Light Codes

At Larry H. Miller Ford Mesa in Mesa, AZ, our certified technicians commonly see codes on the 2017 Ford Taurus such as P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0171 (system too lean), and P0455 (evaporative emission system leak). Each code has real cost implications when ignored: a persistent misfire (P0300) can overheat and destroy a catalytic converter, leading to replacement costs that far exceed timely spark plug or ignition coil repair. A P0420 left unaddressed may mean failing emission tests and expensive exhaust work. P0171 often indicates vacuum leaks or fuel delivery issues that reduce fuel economy and engine life. P0455 EVAP leaks can lead to fueling inconvenience and diagnostic follow-ups. Choosing Larry H. Miller Ford Mesa brings diagnostic clarity—our technicians use OEM-grade tools to pinpoint the root cause, not just clear codes. That accuracy translates to immediate savings on unnecessary parts and long-term protection for your 2017 Ford Taurus.

Check Engine Light Flashing

A flashing check engine light in a 2017 Ford Taurus signals an active misfire or condition that risks immediate engine or emissions system damage.

At Larry H. Miller Ford Mesa we treat flashing conditions as high priority: our team will perform an expedited diagnostic sequence, identify whether it’s an ignition, fuel, or sensor issue, and present clear repair options. We also discuss warranty coverage, OEM parts, and service financing so you can address urgent repairs immediately without deferring necessary work. In many cases our dealership pricing and bundled offers produce better long-term value than a piecemeal approach.

If needed, we can arrange courtesy transportation and keep you informed through every step.

2017 Ford Taurus Check Engine Light Reset

Resetting the check engine light on a 2017 Ford Taurus may clear the warning temporarily, but a reset does not resolve the underlying fault. Dealers like Larry H.

Our technicians use manufacturer-grade tools to capture freeze-frame data and confirm repairs truly resolved the fault; that transparency prevents repeated trips and unplanned expenses.
