Flash: MIL Illumination - Diagnostic and System Improvements
This bulletin involves selectively erasing and reprogramming the Powertrain Control
Module (PCM) with new software.
Some customers may experience a condition that the Oil Life Monitor shows faster then
expected oil life deterioration. Software enhancements will address this issue.
Some customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon
further investigation the Technician may find that any of the following Diagnostic Trouble
Code(s) may have been set:
? P0073 - AMBIENT AIR TEMPERATURE SENSOR CIRCUIT HIGH
? P0088 - FUEL RAIL PRESSURE TOO HIGH
? P016F - CLOSED LOOP FUEL PRESSURE CONTROL AT LIMIT - PRESSURE
