Parts for your 2010 Toyota Camry-Egr valve

2010 Toyota Camry EGR valve — do you have one?

Short answer: if it’s a 2010 Toyota Camry with the regular petrol engines, there’s no EGR (exhaust gas recirculation) valve fitted. If it’s the 2010 Camry Hybrid, there is a cooled EGR system with an EGR valve.

That’s not a guess — it’s straight from the technical docs. Toyota’s service information (TIS) for the 2010 Camry ACV40/GSV40 (the non-hybrid 2.4/2.5 four-cylinder and 3.5 V6) shows no EGR system in the Emission Control section, while the AHV40 Camry Hybrid manual details a cooled EGR valve and cooler. The Toyota Electronic Parts Catalogue backs this up: there’s no EGR valve part listed for the non-hybrid engines, but there is one for the hybrid. Reputable parts catalogues commonly used in workshops (e.g., Toyota Genuine Parts listings, RockAuto/Repco inventories) mirror this: EGR valves appear only for the hybrid model year.

Why the difference? On the non‑hybrid 2010 Camry, Toyota meets emissions targets using variable valve timing (VVT‑i), precise fuel control and a three‑way catalytic converter. VVT‑i can create an “internal EGR” effect by tweaking valve timing to reduce combustion temperatures and NOx, so an external EGR valve isn’t needed. Many 2.5‑litre 2AR‑FE and 3.5‑litre 2GR‑FE engines of this era were designed that way, sometimes with secondary air injection to further tidy up cold‑start emissions. Fewer parts under the bonnet, fewer failure points, and no EGR‑related carbon build‑up to worry about — nice.

If the vehicle is a 2010 Camry Hybrid (2AZ‑FXE), that’s a different setup. The Atkinson‑cycle hybrid engine uses a cooled EGR valve and cooler to cut pumping losses and keep combustion temps in check, which helps both efficiency and NOx control. In that case, EGR maintenance is relevant — periodic cleaning of the valve and cooler can prevent rough running and fault codes as kilometres rack up.

So for a standard 2010 Camry petrol, an EGR valve isn’t part of servicing because it simply isn’t there. For the 2010 Camry Hybrid, it is there and keeping it clean is part of smart long‑term maintenance.
