1991 Toyota MR2 Check Engine Light Flashing

A flashing check engine light on a 1991 Toyota MR2 usually indicates a severe condition such as an engine misfire that can damage the catalytic converter or lead to loss of power. If you see a flashing light, stop driving as soon as it is safe and have the vehicle towed to our dealership; continuing to drive multiplies repair costs and risks safety. At Nalley Toyota of Roswell our factory-trained technicians perform priority diagnostics and isolate ignition, fuel, and sensor faults quickly. We explain immediate repair options, outline long-term savings from proper fixes, and remind customers that warranty-related work must be completed at a certified dealership to remain valid.

1991 Toyota MR2 Check Engine Light Reset

Resetting the check engine light on a 1991 Toyota MR2 can be done by clearing stored trouble codes, but that does not fix the underlying problem. Older MR2 models may respond to simple resets like battery disconnects or use of scan tools, yet codes will return if the cause persists. Getting service at our dealership ensures the root cause is diagnosed and repaired using Toyota-approved parts and procedures. That approach delivers immediate savings by avoiding unnecessary repeat visits and long-term savings through durable repairs. Remember: to maintain warranty coverage, any repairs must be performed at a certified dealership with documented service records.

1991 Toyota MR2 Check Engine Light Codes

Common check engine light codes for a 1991 Toyota MR2 point to misfires, oxygen sensor faults, ignition issues, and emissions system leaks. Ignoring codes can escalate costs: a simple spark plug or coil repair may be under $100–$300, while a damaged catalytic converter can cost $800–$2,000 to replace. Oxygen sensor replacements and fuel system repairs fall in the mid-range, and unresolved misfires can cause expensive engine or exhaust damage. Our dealership provides accurate code reads, transparent estimates, and OEM parts to limit total lifecycle costs. Repairs covered by warranty must be completed at a certified dealership to keep your coverage intact.
