SYMPTOM/CONDITION:
A small number of customers may experience a Malfunction Indicator Lamp (MIL)
illumination. Upon further investigation the technician may find the following Diagnostic
Trouble Codes (DTCs) set in the PCM memory:
•
•
P0335 - Crankshaft Position Sensor Circuit.
P0456 - Evap System Small Leak.
**The following software enhancement is also available:
•
Engine is hard to start at temperatures -29°C (-20°F) for vehicles utilizing E15 fuel
only (Sales Code ECN).**
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all related systems are functioning as designed. If DTCs or
symptom conditions, other than the ones listed above are present, record the issues on the
repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the symptom/condition listed above or if the technician finds any
of the listed DTCs, perform the Repair Procedure.
REPAIR PROCEDURE:
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2
volts. Do not allow the charging voltage to climb above 13.5 volts during the
flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
1. Reprogram the PCM with the latest software. Detailed instructions for flashing control
modules using the wiTECH Diagnostic Application are available by selecting the
application’s “HELP” tab.
2. Clear any DTCs that may have been set in any module due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allows them
to be cleared.
