2023 Toyota RAV4 Check Engine Light Codes

The check engine light on a 2023 Toyota RAV4 can be triggered by a range of OBD-II codes — from evaporative emissions leaks (P0440 series) to oxygen sensor faults (P0130–P0167), misfires (P0300–P0312), or catalytic converter inefficiencies (P0420). In Boston, Herb Chambers Toyota of Boston diagnoses these codes with factory-grade scanners and road-test verification to confirm the exact cause before recommending repairs. Leaving these codes untreated can lead to higher fuel costs, diminished performance, and eventual component failure: a simple gas-cap or sensor fix is low cost and fast, whereas ignoring catalytic converter warnings or persistent misfires can escalate into expensive repairs. Our certified technicians provide transparent pricing, discuss immediate and long-term savings, and apply OEM parts that preserve performance and warranty coverage. For convenience, we offer online scheduling, quick lane service, and service financing so you can address codes promptly without financial stress. Check our current service specials and schedule service to get your RAV4 back to peak condition.
