The check engine light came on in my old RAV4 this morning.
Engine starts and runs smoothly/normal.
Oil level good, Transmission fluid level normal. Coolant levels good. No noise or other external evidence of problems.
What might be some other quick and easy things to check?
I don't have a diagnostic tool so I gotta go old school until tomorrow and I can get it in to a shop.
Would a bad battery cause the check engine light to come on?
