A/C System Pressure Sensor Design Change DTCs B14A3, B14A4, B14EF or B14EE – 2019 Subaru Forester

NHTSA ID Number: 10163531

Manufacturer Communication Number: 10-93-19

Summary

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.
