My 2005 Camry 2005 (90,000 km = ~60,000 miles) has the the engine light on since last Sunday. I have been away for ~30 days and my son, a beginner driver has been the sole driver during this time when the light went on. The engine seems to be working fine, and I do not see any issues when driving. I wonder if anybody has an idea what steps I can take to diagnose the problem before taking it to a Toyota dealer? I do not have the code reader to read the fault number.
Thanks and regards,
Wes
