P014D CHRYSLER MeaningThe engine after treatment system monitor the oxygen content in the diesel engine exhaust. The Powertrain Control Module (PCM) monitor the exhaust gases for oxygen content and varies the rich/lean fuel mixture of the intake air fuel mixture to adjust the system. This diagnosis monitor the status message broadcast by the Smart O2 sensor module for the upstream O2 sensor circuit. The PCM will set the fault if it receives an FMI (failure Mode Indicator) message from the Smart O2 Module. The PCM will illuminate the MIL lamp immediately when the diagnostic runs and fails. The PCM will turn off the MIL lamp diagnostic runs and passes in four consecutive drive cycles.
