Check Engine Light Flashing

A flashing check engine light in a 2025 Toyota RAV4 is a more urgent signal than a steady light — it often indicates a severe misfire that can damage the catalytic converter and rapidly increase repair costs if not addressed immediately.

Choosing our dealership delivers measurable value: precise diagnostics reduce the chance of incorrect parts being installed, and OEM parts preserve reliability and resale value. Warranty-covered work must be completed at a certified dealership to remain valid; we’ll review any applicable coverage and provide transparent pricing that highlights immediate savings and long-term protection for your 2025 Toyota RAV4. Take advantage of our rotating service specials and ask about service financing so you can address urgent repairs now and pay over time.

2025 Toyota RAV4 Check Engine Light Codes

Common diagnostic trouble codes on a 2025 Toyota RAV4 include P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0171/P0174 (system lean), and P0455 (evaporative emission system leak). Each code has different consequences: leaving a P0420 can lead to failed emissions tests and costly catalytic converter replacement; an unchecked P0300 misfire can damage the catalytic converter and reduce engine life; P0171/P0174 often signal vacuum leaks or fuel delivery problems that lower fuel economy; and P0455 typically points to an EVAP leak that may start as a loose gas cap but can progress to more expensive repairs. Herb Chambers Toyota of Boston in Boston, MA, provides efficient, transparent diagnostics and repair plans for these codes. Our factory-certified technicians use OEM parts and proven repair methods to preserve fuel efficiency and extend vehicle longevity. We often cost less than independent shops when considering the accuracy of the diagnosis, the longevity of OEM parts, and fewer return visits.
