Continuing from where we left off. If the pressure values are correct on your gauge set and you are still experiencing this EC light flashing condition then your failed component may very well be the pressure sensor itself. The pressure sensor is mounted to the receiver dryer and is indicated on the diagram below as component B12

Discharge the AC system and replace both the sensor and receiver dryer. Like I said if all pressures are good and you have a charged system this is your most likely failed component.
