2009 Honda CR‑V TX‑Valve: what it does, when to replace, and how to look after it

Yes, the 2009 Honda CR‑V is fitted with a TX‑valve (thermostatic expansion valve). This isn’t guesswork: the Honda CR‑V 2007–2011 Service Manual (HVAC section), Honda’s parts catalogue listing for the A/C expansion valve (commonly referenced as 80220‑SWA‑A01), and major aftermarket catalogues from OE suppliers like Denso and Four Seasons all identify a TX‑valve mounted at the evaporator on this model.

The TX‑valve’s job is to meter refrigerant into the evaporator while maintaining the right superheat, so cabin temps stay steady without the evaporator icing up. On the 2009 CR‑V, it’s a precision component that responds to evaporator outlet temperature and pressure, opening and closing just enough to match heat load. When it’s working right, owners get quick pull‑down on hot days and stable, chilly air at the vents.

It’s not a routine maintenance item, but it’s smart to assess the TX‑valve any time the system is opened or the compressor is replaced. Typical clues the valve is sticking or restricted include weak or intermittent cooling, frosty or sweaty lines at the firewall, hissing that comes and goes, and odd high/low pressure readings on the gauges. Because access is at the evaporator, expect a fair bit of trim and glovebox area removal on the CR‑V to reach it safely.

Best practice during replacement or major air‑con work on this Honda:

• Use a licenced air‑con tech to recover refrigerant, evacuate, and recharge to the under‑bonnet R‑134a spec with the correct PAG oil.
• Replace the TX‑valve and all related O‑rings, lightly oil the new seals.
• Address contamination: if there’s compressor debris, don’t try to “flush” through the TX‑valve. Flush lines where appropriate, and replace the condenser if it’s a parallel‑flow type that can’t be cleaned properly.
• Renew the receiver/drier or desiccant element (on many CR‑Vs it’s integrated with the condenser) any time the system’s been open.
• Leak‑test under vacuum and with nitrogen where possible, then verify vent temps and pressure readings once charged.

Look after the CR‑V’s air‑con by running it regularly year‑round, keeping the condenser face clean, and getting the system pressure‑checked if cooling performance changes. A healthy TX‑valve helps the whole system work smarter, not harder—ideal for Aussie and Kiwi summers.

FAQs

Does the 2009 Honda CR‑V use a TX‑valve or an orifice tube?
It uses a TX‑valve at the evaporator. Honda service information and parts catalogues for the 2007–2011 CR‑V platform list an A/C expansion (TX) valve, not an orifice tube.

What are common signs the TX‑valve is failing on a 2009 CR‑V?
Slow or inconsistent cooling, fluctuating vent temps, frost on the low‑side line at the firewall, and odd gauge readings (very low low‑side or abnormally high high‑side). A stuck‑shut valve starves the evaporator, a stuck‑open valve can lead to poor cooling and potential icing.

How long does TX‑valve replacement take and what else should be replaced?
Allow several hours of labour due to access at the evaporator area. It’s wise to replace O‑rings and renew the receiver/drier or desiccant. If there’s compressor failure debris, plan on system cleaning and often a new condenser.
