2011 Honda CR‑V TX Valve: What it does, where it lives, and how to look after it

Yes, the 2011 Honda CR‑V uses a thermal expansion valve (TX valve). This is confirmed by factory and parts documentation: the Honda CR‑V 2007–2011 Service Manual details an A/C expansion valve mounted at the evaporator, and the Honda Genuine Parts catalogue lists an “Expansion Valve (A/C)” for these models. Major aftermarket catalogues (e.g., DENSO and Four Seasons) also supply a direct‑fit TX valve for the 2011 CR‑V. So, the TX valve is absolutely relevant on this vehicle.

The TX valve meters R‑134a into the evaporator based on temperature and pressure feedback, keeping the evaporator at the sweet spot (correct superheat) for crisp, consistent cooling without flooding the compressor. It adapts flow to driving and climate conditions, helping the CR‑V deliver steady cabin temps while protecting the A/C hardware.

When a TX valve plays up, the cabin often tells the story. Common signs include:

• Weak or intermittent cooling, or big swings in vent temperature
• Frost or icing on the evaporator lines or case
• Rapid compressor cycling or odd hissing/chattering
• Pressure readings that don’t make sense (e.g., very low suction if stuck closed, high suction and high head if stuck open)

On the 2011 CR‑V, the TX valve is fitted at the evaporator inlet inside the cabin (behind the dash on the passenger side). Access typically involves removing the glovebox/trim and HVAC covers, expect moderate labour time. Any TX valve replacement requires full refrigerant recovery, new O‑rings lubricated with the correct PAG oil, and attention to moisture control—replace the receiver/drier or the condenser’s desiccant pack as specified for this model. After reassembly, the system needs a proper vacuum hold, then a recharge by weight to the R‑134a spec (commonly around 500–550 g for this generation, always check the under‑bonnet label or service manual). Oil type is ND‑OIL 8 (PAG 46), with quantity adjusted for components replaced. A post‑service check should confirm stable pressures, good vent temps, and correct compressor cycling.

Because releasing refrigerant is illegal and unsafe in Australia and New Zealand, all A/C work should be done by a licensed automotive A/C technician (ARCTick in Australia or a suitably certified tech in NZ). To keep the TX valve and evaporator happy, replace the cabin filter on time, run the A/C regularly year‑round, and keep the condenser clean so the system isn’t overworked.

Popular questions

Where is the TX valve on a 2011 Honda CR‑V?
It’s mounted at the evaporator inlet inside the cabin, on the passenger side of the dash within the HVAC case. Access generally requires glovebox and trim removal and, sometimes, partial HVAC case access. The system must be evacuated before disconnecting lines.

Does the 2011 CR‑V use a TX valve or an orifice tube?
It uses a TX valve. This is documented in the Honda CR‑V 2007–2011 Service Manual and reflected in Honda’s parts catalogue and major aftermarket listings for the 2011 model.

What refrigerant and oil does it use, and how much?
The 2011 CR‑V uses R‑134a and ND‑OIL 8 (PAG 46). The typical refrigerant charge for this generation is roughly 500–550 g, but always follow the exact figure on the under‑bonnet label or the service manual. Oil amount depends on what’s been replaced.
