What is indicated by the check engine light on a 2003 Camry?

Question

Accepted Answer

In the 2003 Toyota Camry, when the check engine light comes on, it could indicate various issues. It might be a simple problem like a loose, damaged, or missing gas cap, or it could be related to the oxygen sensor. Alternatively, it could be more severe, such as an engine misfire affecting the catalytic converter. To determine if the gas cap is the issue, you can drive for a while to see if it resolves itself or try tightening the cap. If the problem is with the oxygen sensor, a replacement typically costs between $30 and $70. Resetting the check engine light can be done by disconnecting the battery for around 20 minutes, then reconnecting it.
