Frequently Asked Questions

What is the most common reason for check engine light on a 2023 Toyota RAV4?

• Loose or damaged gas cap: the easiest and most frequent trigger; often resolved with a tightened or replaced cap.
• Faulty oxygen sensor: can affect fuel economy and emissions if left unaddressed.
• Catalytic converter wear: a costly issue that reduces performance and increases emissions if ignored.
• Ignition system faults (coils/plugs): poor combustion, misfires, and drivability problems can follow.
