'90 accord ecu code 43

Hi all,

My 90 accord has about 255,000km, it drives great and it's been
maintained well.

A few days ago, my engine light came on while driving < 60 on
a downward slope in town. Now the light comes back consistently at speeds
over > 80 when I drive on the highway. I've reset the ecu with no avail.

I get the ecu code 43. I see 4 long flashes, 3 short ones followed by a
pause, a short flash and then everything repeats again.


Some people on the newsgroup mentioned a potential oxygen sensor problem.
What are the costs (parts and labour) for this kind of problem in Canada ?

thanks in advance,
-Vlad

Thanks Jim,

I realize code 1 is the oxygen sensor and some rule of thumb says it
appears together with code 43.

Does anyone know the labour costs involved? Is it < 1 hour kind of job?

thanks again

Call your local service shop or dealer and get a quote. Prices vary
everywhere so any price quoted here is meaningless.

Any improvement done ? How slowly can your engine idle @ ?

i wouldn't rely on that. best to get the honda manual from helm.com
[for the diagnostics] and search tegger.com for tsb's.

 

Hi All,

I was getting a 43 code (fuel system) followed by a 1 (oxygen sensor).
My symptoms were a few random losses of power at small speeds and high
gas consumption, partly also attributable to the cold weather
conditions in Ontario.

My mechanic checked the fuel pressure (code 43) and found nothing
wrong. So we went and replaced the O2 sensor with an OEM one and the check
engine light is now gone. The car also `seems' to me to have better
acceleration and smaller rpms at high speeds.
