Just a quick question to see how long people wait to change o2 sensors? Do you know any symptoms of them being bad (besides low gas mileage?)

Thanks

 

i have seen people say they're good up to 100k... don't know how accurate that is.

 

im pretty sure that it is 100k as stated in the honda manuals.

 

One of mine just went out at 90K the other one is good although i bought two just in case... You can take a voltage meter and see how many volts are going to it if its low then you can change them because they are starting to go bad...you could just wait till the malfunction idicator lamp came on like me :-D

 

hmmm... i'm at 200k
no lamp (engine light - i assume)

any other indication besides "low mileage" and the light?

 

Back-probe that shiz

 

mine was REALLY bad but the light never came on unless I did something to the car that would make it come on. My oil pressure switch was bad but the car wouldn't realize it until I tried to go into 5th gear vtec and then it would throw codes for that, the o2, and the map sensor...

 

mine went at 180K and ever since i replaced them, gas mileage improved big time. Even when i never got the engine light, i was getting bad gas mileage cus it was worned.

 

OMG i got cusious and checked out the pricing of o2 sensors and i found a 98 prelude o2 sensor going for $250! i thought they were more like $60-$80. the price i found was on schuck's website. is there some kind of core charge/refund i'm missing? $250 sounds like a wideband sensor price, not a narrow band sensor. sorry, not trying to thread jack.

 

i know you said 5th gen, but i have a 4th gen, and i thought i had seen them for around $100. checked ebay and was correct:
