How do I change a downstream O2 sensor (located after catalytic converter) on 2001 chevy prizm?
Do I have to heat up the sensor to loosen it? Any diagrams or really really really detailed instructions would help... Thanks :)

Jack up the car, unplug the sensor, and then unscrew it. It's not hard. It might be very tight from corrosion, but it is a Toyota so it should come apart easily.
