Flash: 1.4L Diagnostic And System Improvements
This bulletin involves selectively erasing and reprogramming the Powertrain Control
Module (PCM) with new software.
A small number of customers may experience a crank no start condition in extreme cold
temperatures of -4°F (-20°C) partially due to the available fuel blend conditions. They may
also experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation
the Technician may find that Diagnostic Trouble Code P0141 - O2 SENSOR 1/2 HEATER
PERFORMANCE has been set in the PCM.
