2015 Honda CR‑V TX Valve: What It Does and How to Look After It

Yes, the 2015 Honda CR‑V uses a TX valve (thermostatic expansion valve) in its air‑conditioning system. This is confirmed in Honda service information for the 2015 CR‑V HVAC section covering the evaporator unit and refrigerant metering, and by OEM parts catalogues listing the “Valve Assembly, Expansion” (commonly referenced as 80220‑T0A‑A01) for 2012–2016 CR‑V models. DENSO technical literature for Honda applications also specifies a TXV‑type metering device rather than an orifice tube for this platform.

The TX valve’s job is to meter the flow of R‑134a into the evaporator based on temperature at the evaporator outlet (superheat). By constantly trimming refrigerant flow, it keeps the evaporator cold without letting it freeze up, protects the compressor from liquid slugging, and stabilises vent temperatures. When the TXV sticks or clogs, you’ll often notice weak or inconsistent cooling, short cycling, frost on the evaporator pipes, or odd high/low side pressure readings during a gauge test.

There’s no scheduled maintenance just for the TX valve, but it should be inspected or replaced if the system’s been contaminated (compressor failure, desiccant breakdown) or if diagnostics point to a metering fault. On the 2015 CR‑V the valve sits at the evaporator, so access typically involves working near the heater/evaporator case. Best practice is to evacuate and recover the refrigerant, replace the TXV with new O‑rings, renew the receiver/drier (desiccant), and ensure the correct PAG oil type and quantity are used (Honda/DENSO ND‑OIL 8 for this model). Always evacuate to deep vacuum, leak‑test, then recharge to the specified R‑134a fill.

• Common signs of a dodgy TX valve
  • Slow or fluctuating cooling at idle and cruise
  • Frost or sweat on one line and not the other near the firewall
  • High high‑side with starving low‑side, or the reverse, on manifold gauges
  • Compressor chatter or rapid cycling
• Replacement tips for the CR‑V
  • Use the correct valve and O‑rings, lubricate O‑rings with the specified oil
  • Replace the drier and fit a new cabin filter to help airflow
  • Follow Honda torque specs and sealing procedures to avoid leaks
  • Charge strictly to weight with R‑134a, don’t “top up by feel”

A technician will usually confirm a TXV fault by comparing vent temps with pressure readings and line temperatures, ruling out issues like condenser fan faults or a weak compressor. Look after the CR‑V’s A/C with clean condenser fins, a fresh cabin filter, and the right charge, and the TX valve will generally deliver years of drama‑free cooling.

Popular questions about 2015 Honda CR‑V TX valve

Does a 2015 Honda CR‑V have a TX valve or an orifice tube?
It has a thermostatic expansion valve (TXV). Honda service information and OEM parts catalogues for the 2015 CR‑V specify an expansion valve mounted at the evaporator, not an orifice tube.

What are the signs the TX valve needs replacing on a 2015 CR‑V?
Expect weak or inconsistent cooling, frosting on lines near the firewall, rapid compressor cycling, and pressure readings that show a starved evaporator or abnormally high head pressure. After ruling out condenser airflow and compressor issues, a stuck or restricted TXV is a common culprit.

How much refrigerant and oil does the 2015 CR‑V A/C system take?
The 2015 CR‑V uses R‑134a. Charge amount and oil quantity are specified on the under‑bonnet A/C label and in Honda service data. Use the correct PAG oil type (Honda/DENSO ND‑OIL 8) and charge strictly to weight after evacuating and leak‑testing.
