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.

SOLENOIDS.
8. From the SINGLE SOLENOIDS MENU, activate
the EVAP bypass solenoid valve. Listen for a click
and feel for a light tap from the solenoid valve as
you activate it.
• If you can hear the solenoid valve click or feel it
tap when activated, disregard this service
bulletin, and look for other possible causes.
• If you cannot hear the solenoid valve click or feel
it tap when activated, go to step 9.
9. Replace the EVAP bypass solenoid valve (see
section 11 of the appropriate service manual).
10. Test the new solenoid valve with the PGM Tester.
• If you can hear the solenoid valve click or feel it
tap when activated, go to step 15 or 16 as
appropriate.
• If you cannot hear the solenoid valve click or feel
it tap when activated, go to step 11.
11. Check the wire harness and the connectors for
damage.
• If you find any damage, repair it, then go to
step 12.
• If you find no damage in the wire harness or
connectors, go to step 13.
12. Test the solenoid valve again with the PGM Tester.
• If you can hear the solenoid valve click or feel it
tap when activated, go to step 15 or 16 as
appropriate.
• If you cannot hear the solenoid valve click or feel
it tap when activated, go to step 13.
13. Replace the ECM/PCM (see section 11 of the
appropriate service manual).
14. Use the PGM Tester to retest the solenoid valve.
• If you can hear the solenoid valve click or feel it
tap when activated, go to step 15 or 16 as
appropriate.
• If you still cannot hear the solenoid valve click or
feel it tap when activated, continue with normal
troubleshooting.
15. Insight only: Disconnect the PGM Tester, and
return the vehicle to your customer.
16. All other affected models: Use the PGM Tester to
run the EVAP system function test (see
S/B 02-007, EVAP System Function Testing and
Diagnostics With the PGM Tester).
• If the EVAP system passes the function test,
disconnect the PGM Tester, and return the
vehicle to your customer.
• If the EVAP system fails the function test,
continue with normal troubleshooting.
