Hi there,

I have Honda Civic 97 CX automatic with 80K on it. The check engine light started going orange all the time when my car is running. I got OBD2 car reader and got the following error message: “O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)”.

What does it mean?
Is it safe to drive my car while this CEL is on?
How big deal is to replace this sensor (should it be replaced) and how much it costs?

Thanks,

Vox
