i was wondering how you can tell if the oxygen sensors are shot?

 

your car *should* throw a yellow checklight / code but from what I understand, it takes alot of f'ing up before an OBDI O2 sensor will throw a code. The margin of error for OBDII cars (96+) is alot smaller and they will throw a code waay before we OBDI cars will.

 

my car has 89,000 miles on it. my gas milage suck. i get 20mpg and on highway about 26 mpg.
is there any way i can tell for sure what is wrong?
is there anything else that i should check up on?

 

is there any other way of knowing when it is shot?

 

what year is your accord? i have a 94 we have 1 o2 sensor to change saves us a few hundred bucks there...buy the oxygen sensor socket, take it out and inspect it, do a search for "oxygen sensor" some1 put up a pictorial chart about the conditions of o2's in the archived section of accord...

 

the best way is to use a DSO, and check for rise time is should be under 100ms anything higher than that the O2 is slow in response. test: induce propane/ or disconnect fpr hose and watch the signal go rich and when it drops below 175mv snap the throttle and freeze the screen and check for rise time.

 

Well an easy way is gas consomption will go waaaay up!
