Parts for your 2010 Honda Cr-v-Egr valve

2010 Honda CR‑V EGR valve — is there one, and does it matter?

Short answer for Aussie and Kiwi owners: the 2010 Honda CR‑V 2.4‑litre petrol (RE series, K24Z engine) does not use a separate EGR valve. That’s not guesswork — Honda’s 2007–2011 CR‑V Service Manual (Fuel & Emissions overview for the K24Z) notes internal EGR control via VTC/i‑VTEC with no external EGR valve fitted, and the Honda Electronic Parts Catalogue for RE models lists no EGR valve assembly for the petrol variants. Autodata’s engine management references for the K24Z back this up by showing no discrete EGR component in the emissions layout.

Why’s there no EGR valve? Honda engineered the K‑series petrol to meet emissions targets by using variable cam timing to create internal EGR. By advancing/retarding cam timing, a controlled amount of exhaust gas stays in the cylinder, lowering combustion temperatures and reducing NOx — the same end goal as a traditional EGR valve, just without the extra hardware. Fewer parts under the bonnet, fewer potential vacuum leaks, and no EGR passages to gum up with carbon. It’s a tidy solution that helps the CR‑V hit ADR/Euro and ULEV‑type emissions standards for its day.

What should owners do instead of “EGR maintenance”? Keep the rest of the air and emissions gear happy. That’s where drivability and emissions gains actually show on this model.

• Schedule throttle body and intake cleaning if idle hunts or feels rough.
• Replace the PCV valve if it’s original or there’s oil mist in the intake.
• Use quality fuel and stick to regular servicing to prevent carbon build‑up.
• Scan for codes if the MIL pops on — you won’t see EGR faults, but you may catch O2 sensor or mixture‑related issues early.

If you’re hunting for an EGR valve location on a 2010 petrol CR‑V, you’ll be looking forever — it’s simply not fitted. Note that some overseas diesel CR‑V engines of a similar era do use EGR, but that doesn’t apply to the AU/NZ‑spec 2.4‑litre petrol.

Where is the EGR valve on a 2010 Honda CR‑V petrol?

It isn’t there. The AU/NZ 2.4‑litre petrol K24Z uses internal EGR via i‑VTEC/VTC, so there’s no external EGR valve or EGR pipework to find or service. If someone’s quoting for an EGR clean on this engine, that job doesn’t apply.

How does the 2010 CR‑V control NOx without an EGR valve?

By tweaking cam timing to keep a measured amount of exhaust gas in the cylinder, which cools combustion and cuts NOx. The ECU coordinates this with oxygen sensors and catalytic converter efficiency to meet emissions without a dedicated EGR assembly.

Do I need to clean EGR passages on this model?

No. There are no external EGR passages to block on the petrol K24Z. If it’s feeling a bit doughy off the mark or idling rough, look to throttle body deposits, a tired PCV valve, spark plugs, or intake leaks instead, and scan for any stored fault codes.
