On the Prelude there are 2 O2 Sensors. They are on the exhaust manifold on the front of the engine. You will need to remove part of the plastic air intake in order to reach them.
The O2 sensor on a Honda Prelude is found on the exhaust pipes of the vehicle. They are located near the catalytic converter which is place on the underside of the chassis.
you possibly blew a fuse. it may not be related to you O2 sensor
m18x1.5 is the threading for Honda civic/del sols, and probably most other o2 sensor bungs
its a 2006 Honda accord
probably one located just after the engine on the exhaust. by now this sensor will be stuffed
That would be the O2 sensor after the catalytic converter.
All O2 sensors are screwed into the exhaust system.
Close to the Intake Manifold
put in a new O2 sensor. The O2 sensor sends a signal to the computer on how rich or how lean to run the engine. It diagnoses the ratio of fuel to air. Once you get an O2 sensor pretty much carboned up, there is not much hope of fixing it, just buy new. Running it too rich for too long will also foul up your plugs, and your cat converter too
The location of a o2 sensor on a 1996 Honda Accord is on the exhaust pipe. These parts help regulate the emissions for the vehicle and are placed on the down pipe of the exhaust system.
4 wires, the black ones are the O2 heater (on the sensor side), the white and green are the O2 sensor itself
the o2 sensor is in the exaust manifold or down pipe it looks like a sparkplug with wires
