On my 2000 TL the evaporative emmission control system shows code P1457. How can I eliminate the system and keep the check engine light off?

 

What did you do to fix the problem? My 2001 Civic doing the same, getting mixed opinions and dealer claims computer needs replacement. I am not spending $900+. Thanks

 

Karen,
I haven't solved the problem. I also don't want to buy a new computer. I still think there must be some way to fool the computer inputs in order to keep the light off.

PROBABLE CAUSE
The EVAP bypass solenoid valve can fail due to
corrosion. The solenoid valve may get water inside. If
the water contains road salt, the solenoid windings
could corrode, causing the valve to fail. In a few rare
instances, the corrosion could be severe enough to
cause an internal short in the solenoid valve, which
could damage the ECM/PCM. If this happens, both the
bypass solenoid valve and the ECM/PCM would need
to be replaced.
Vehicles driven in the Northeastern part of the U.S. are
more likely to have this problem because of the salting
of roads during the winter months. Vehicles driven
where salt is not used on the roads are much less likely
to have this problem.
