This bulletin announces a design change made to the air conditioner’s pressure sensor to address
customer concerns of the system blowing warm or not blowing cold air. In some cases, preliminary
diagnosis may find codes B14A3, B14A4, B14EF or B14EE present. Review of actual system
pressures using a manifold gauge set and comparing against values seen using the Subaru Select
Monitor (SSM) may show the SSM readings much lower than the actual readings. These are all
indications of a possible pressure sensor concern.
