engine sensor light is flashing

Go to Autozone and have the codes read. Post them back here. The check engine light is on for a reason. Did your mechanic ever say why it was on to begin with? Did he give you an error code?

My mechanic said it's typical of Honda cars. I'll check out Autozone. Thank you for your response.

That's the standard canned response a mechanic gives for 'I don't know" Like Reelin68 said, it's on for a reason -- a fault has been detected by the OBDII and a flashing light indicates a more serious fault than a steady on. There is nothing 'typical' about it. Honda is a well-engineered car Do what Reelin68 suggested asap

Nuff Said! Your mechanic is a jerk.
