My 1992 toyota camry had a light just come on it says power. What the funk does that mean?

Help

Do you have a button on the shifter or somewhere else in the car that says power/econ (economy)

i have an overdive

its a green light though

most of the time it means what I said early, that you have a power/economy switch but if you don't have 1 than...
could mean the alternator other than that I am at a loss.

than somewhere should be a power/econ switch or something to that affect

thanks man

ya on toyotas it would be an ECT power switch and if its not near the shifter or to the left of the steering wheel...its not it, and its probably a light thats not good.
