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.

INTRODUCTION:

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.

 

PRODUCTION CHANGE INFORMATION:

The new sensor was incorporated into production starting with VIN KH552558.

 

PART INFORMATION:

The part number for the new pressure sensor is: 73414SJ010.

Supertech R-134a Refrigerant Automotive use in a 12oz Self-Sealing Container (3 Pack)

  • NEW GAS - SuperTech gas is brand new and never reclaimed or recycled. We purchase our R134a multiple times per year ensuring you get fresh made refrigerant. Old refrigerants can begin to rust and can cause performance issues if used.
  • SSV CANS - Our cans are equipped with the 50 State compliant self-sealing valve design. You can store partially used R134a cans. Note, older can taps may not work on this valve type and you may need to purchase a R134a can tap to work with all SSV cans

Leak Saver 134a Replacement Refrigerant for MVAC, HVACR, Automotive - R-134a for MVAC use in a 8-Ounce Container - 3 Pack
  • WORKS WITH ALL 134a SYSTEMS: Our 134a Replacement Refrigerant is compatible with all systems and lubricants that are designed to be used with 134a refrigerant or that have been retrofitted to use 134a. It can be used in cars, trucks, refrigerators, RVs, boats, tractors, combines, ice machines, milk processing equipment, and any other equipment calling for R-134a. You must follow all EPA guidelines when handling this refrigerant.
  • COLDER FORMULA WITH LOWER HEAD PRESSURES: Our refrigerant is a specially engineered hydrocarbon formula that operates at a lower head (high side) pressure than standard 134a. This can allow your compressor to run smoother and have improved cooling and performance properties. This is our coldest and highest performing refrigerant formula. When charging, our 134a Replacement Refrigerant is easily installed using the same pressure parameters as standard 134a.
  • USES LESS REFRIGERANT BY WEIGHT: Our 134a Replacement Refrigerant is physically lighter than standard 134a refrigerant. Each 8oz can of 134a Replacement Refrigerant is equal to 21oz of standard 134a refrigerant (a 1:2.6 weight ratio). That means that if you want to add 12oz of standard 134a refrigerant to a system, you will only need to add 4.6oz of our 134a Replacement Refrigerant. This translates to using up to 60% less refrigerant for a proper charge.
  • PROVEN FORMULA THAT IS ENVIRONMENTALLY SAFE: The Leak Saver 134a Replacement Refrigerant formula is 100% USA Made. It is designed to be a climate-friendly green alternative to standard 134a and is non-ozone depleting and has zero Global Warming Potential (GWP). On the other hand, standard R-134a is an HFC (hydrofluorocarbon) greenhouse gas and has a high (GWP). Please note that this refrigerant is flammable and has been safely sold for all the listed applications for over 28 years.
  • YOUR SATISFACTION IS OUR PRIORITY: We stand 100% behind the effectiveness of our products. If for any reason you are not satisfied with your product, please contact us, and we will make it right.
