Question

How many o2 sensors in honda civic so 2008

Answer 1

Hi there,

The car has 2 O2 sensors, the front one in the exhaust system is also called an A/F sensor. It's a little more complex then the rear O2 sensor is all. The rear O2 sensor is mounted after the catalytic converter in the exhaust steam. Bank 1 sensor 1 is the a/f sensor BEFORE the converter, bank 1 sensor 2 is AFTER the converter.
