MIL Comes On With DTC P1457: EVAP Bypass Solenoid Valve Failure
SYMPTOM
The MIL is on, and DTC P1457 [leak detected in EVAP control system (EVAP control canister system)] is set.
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.
