Dart Reprogram

This bulletin applies to 2013-2014 Dodge Dart vehicles equipped with a 2.4L engine, built on or before Feb. 14, 2014. The MIL may be on with DTC P2251 (O2 sensor 1/1 negative current control circuit open).

The fix involves selectively erasing and reprogramming the PCM with new software, using software level release 14.02 or higher.

Using a scan tool (wiTECH) with the appropriate diagnostic procedures available in TechCONNECT, verify that all engine systems are functioning as designed. If DTCs other than the one listed here are present, record and repair as needed before proceeding.

Install a battery charger to maintain battery voltage above 13.2 and below 13.5 volts.

Reprogram the PCM following procedures available in DealerCONNECT/TechCONNECT. Refer to Group 89 – Electrical > Electronic Control Modules – Service Information > Module – Powertrain Control > Standard Procedures > PCM/ECM Programming.

After PCM reprogramming, clear any DTCs that may have set in other modules.
