## NHTSA's summary

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 TOO LOW ? P0420 \- CATALYST EFFICIENCY \(BANK 1\) ? P0426 \- CATALYST TEMPERATURE SENSOR CIRCUIT PERFORMANCE \(BANK 1 SENSOR 1\) ? P05F8 \- REDUCTANT HEATER CONTROL MODULE PERFORMANCE ? P061B \- INTERNAL CONTROL MODULE TORQUE CALCULATION PERFORMANCE ?
