Hondas with MAFs instead of MAPs.

Just for reference, this is a list (as of 2007) of Honda models that use
Mass Air Flow sensors to directly measure air flow instead of a combination
of sensors (including Manifold Absolute Pressure) to estimate it:


’03-04 Accord L4 ULEV,
’05-07 Accord L4,
’06-07 Civic,
’07 CR-V,
’07 Element,
’07 Odyssey.

There may be more models, but these are all that are listed by my source.

 

i think this must be the bean counters in action looking for life
limitation opportunities. mass air flow sensors utilize moving parts
that must be set just right and which are subject to wear. manifold air
pressure sensors otoh are immune from wear and require no setting.
sure, maf sensors seem to last a decent enough time, but the honda
system, with no moving parts, cannot wear out at all.

 

Many mass air flow sensors use a pair of thermistors, or just hot wires.
No moving parts. Fast response. No wear. Easy to measure.

And yet VW manages to screw up even that particular concept.

 

98 and 99 civics were having their MAP sensors replaced in droves up here in
Winnipeg about 3-4 years ago... My sister had hers done 3 times. Something
to do with the cold weather (it was January).

My 98 civic never had that problem, though I am aware of at least 10 other
people with civics of this age that did...
