2010 Honda CR‑V TX‑Valve: What it does, and when to sort it out

Based on technical references, the 2010 Honda CR‑V does use a thermal expansion valve (TX‑valve). Honda’s factory service manual for the 2007–2011 CR‑V HVAC section specifies an “expansion valve” at the evaporator. The Honda electronic parts catalogue lists an A/C Expansion Valve (commonly referenced as 80220‑SWA‑A01) for this model, and major parts catalogues from OEM suppliers (e.g., DENSO) and aftermarket brands also carry a direct‑fit TX‑valve for the 2010 CR‑V. So yes—this model is built around a TX‑valve system, not a fixed orifice tube.

On a 2010 CR‑V, the TX‑valve meters refrigerant into the evaporator based on temperature and pressure, keeping the air‑con cool without freezing the core. It helps stabilise vent temps in Aussie and Kiwi conditions, whether it’s a quick run to the shops or a long motorway slog in summer. When the valve sticks or drifts out of spec, drivers might cop weak cooling at idle, temps that swing hot‑cold, icing on lines, or a compressor that short‑cycles.

The valve is mounted at the evaporator in the HVAC case (behind the dash, accessed from the passenger side). Replacement is a moderate‑to‑advanced job because the refrigerant must be recovered and the evaporator housing accessed. For anyone servicing a 2010 CR‑V TX‑valve, best practice is:

• Recover the R‑134a properly, never vent. Charge by weight to the under‑bonnet spec after repairs.
• Replace the receiver/drier or desiccant bag whenever the system is opened, and fit new green HNBR O‑rings lubricated with the correct PAG oil.
• Pull a deep vacuum and verify it holds, pressure‑test with dry nitrogen if there’s any doubt.
• Weigh in the exact refrigerant charge, don’t just “top up”.
• Check condenser fans, cabin filter, and look for debris blocking the condenser—simple wins for cooler vents.

Owners will often notice TX‑valve issues as mediocre cooling on warmer days or a system that’s brilliant on the open road but average in traffic. A qualified A/C tech can confirm with pressure readings: a stuck‑closed valve shows low suction and low discharge, a stuck‑open valve shows high suction with poor cooling. If the valve is replaced, it’s a good shout to inspect the evaporator for contamination and ensure the drain is clear, keeping the cabin fresh and fog‑free.

With the right parts and proper procedures, the CR‑V’s air‑con goes back to blowing crisp, reliable cold—exactly what’s wanted across Australia and New Zealand.

Popular questions about the 2010 Honda CR‑V TX‑valve

Does the 2010 CR‑V actually have a TX‑valve?
Yes. Honda’s service literature shows an evaporator‑mounted expansion valve, and the Honda parts catalogue lists an expansion valve specific to the 2010 CR‑V. OEM and aftermarket catalogues back this up.

Where is the TX‑valve on a 2010 CR‑V?
It’s fixed to the evaporator inside the HVAC case behind the dash, accessed from the passenger side. The refrigerant lines pass through the firewall to it. Access typically requires recovering refrigerant and removing trim and the evaporator unit.

Can someone drive with a dodgy TX‑valve?
It’ll usually drive, but cooling can be poor, the system may ice up or short‑cycle, and the compressor could cop extra stress. It’s best to get it diagnosed and repaired to avoid bigger bills and sweaty trips.
