CEL came on last Friday throwing code P144C. “EVAP SYSTEM PURGE FLOW PERFORMANCE DURING BOOST”. Took it to the dealer and they suggested reprogramming the PCM per the TSB for the 3.5L. (Mine was made at the KC plant during the time periods for the TSB).Since the purge valve is still open, a vacuum is applied to the entire fuel system. The PCM closes the purge valve and monitors the fuel pressure valve to see if it holds steady. If the vacuum deteriorates, the PCM will set an evaporative emissions code, based on the rate of vacuum deterioration. What causes an evaporative emissions trouble codeA) Canister purge valve.
