• Confirm whether the light is steady or flashing; a flashing light usually indicates a severe issue (see next section) and requires immediate attention.

2025 Ford Expedition Check Engine Light Codes

The check engine light on a 2025 Ford Expedition often returns standardized OBD-II codes such as P0300 (random/multiple cylinder misfire), P0420 (catalyst system efficiency below threshold), P0171 (system too lean), P0442/P0455 (evap small/large leak), and various oxygen sensor codes. In Deland, FL, Coggin Deland Ford’s service center interprets these codes in context—matching code data with live sensor readings, freeze-frame data, and road tests to prevent unnecessary parts replacement. Ignoring a P0300 misfire, for example, can lead to damaged pistons or a ruined catalytic converter, increasing repair costs from a simple ignition or injector repair to thousands of dollars in component replacement. A P0420 code left unresolved often means diminished fuel economy and potential emissions failure; early action with OEM catalysts or sensor replacement preserves performance and keeps you compliant. At Coggin Deland Ford, our factory-trained technicians provide an honest estimate and explain both immediate and long-term savings. We use OEM parts, maintain warranty compliance, and offer service financing so you can address issues now and avoid greater expense.

2025 Ford Expedition Check Engine Light Reset

Resetting the check engine light on a 2025 Ford Expedition should follow diagnosis and repair, not precede it. While many scanners can clear codes, a cleared light without repair masks persistent faults that may worsen over time. At Coggin Deland Ford, we use OEM-level diagnostic tools to identify root causes, complete repairs with genuine Ford parts, and only reset the system after confirming the fault has been resolved. This protects your vehicle’s warranty and long-term drivability. Our transparent process includes detailed estimates, warranty coverage explanations, and options for service financing so you can complete necessary repairs without delay. Choosing dealership service often costs less over time because we prevent repeat visits and secondary failures with accurate fixes and quality parts. We also publish service specials to help reduce out-of-pocket expense—check them before you visit. For reliable service and peace of mind, schedule appointment online or review our service specials to save on maintenance.
