Lexus Troubleshooting Questions? Ask a Lexus Expert
Hello. Welcome to Just Answer. Please allow me to assist you. Without knowing exactly what codes were read and cleared, it is hard to say exactly what the root cause is. Would you happen to have the print-out of the codes? If not, and the light stayed off for 800 miles, I would be inclined to think that you have an emission control issue....either an oxygen sensor or a possible a fuel cap issue. If you had the codes that would be a tremendous help. Please advise.
