Im a ebay junky. http://cgi.ebay.com.au/OEM-HONDA-INT...item43a37b75f0 Is what found. Still a bit steep . Try wrecker's for second hand's would be my bet?? Worst case. Look up resistance of the sensor at cold temp. Go 2 jaycar and buy the closest resistor 2 that.. Solder that 2 the original cable and leave it until something cheap comes your way!!!! P.s car may run rich or 2 lean.. Only a short term fix!!!!

^ For your sake I hope you're running rich and not lean.

https://oemacuraparts.com/ is a good place to shop for OEM parts especially when our exchange atm.

Btw have you confirmed which o2 sensor you have to replace? Primary or secondary?

im not excatly sure, is there anyway to find out without doing diagnostic at honda ect??

btw car doesnt seem to be running badly at all? is it ment to wht a bad o2 sensor?

[Karl]

Well all the sensor does is check the temp of the air. determining what fuel to air ratio is best. As colder air compresses better. If your car is running rich your are burning 2 much fuel to air.. You'll create alot of carbon build up in your exhaust(way 2 check touch inside of exhaust if very black powdery stuff.. Alot of carbon. Alittle normal). If lean it may stall miss firer and carry on. Better run rich and waist petrol!!!! Why you changing it??? The way to test it. Start car on cold morning test the Resistance it's giving.. Then test with warmer weather. Resistance should be differ not sure higher or lower depend on set up.. Note the difference may be within like 0.001 of ohm..

My bad got confused. Thought it was the intake sensor.

from memory the 02 is inactive till the engine warms up?

why do u wanna change ur 02 sensor ?

[tinkerbell]

yes, but it is moreso that the O2 sensor is 'active' once the ignition is on,

but its input is ignored by the ECU unless several parameters (such as ECT, TPS and MAP) are met...

(nb - it is O2 not 02)

thanks for the corrections tink ..i missed them lol the heater in the O2 is active from startup am i correct ?

[tinkerbell]

yes grasshopper - you are correct

it will be destroyed if not heated and exposed to exhaust gas...
