In a 1997 Camry, the Exhaust Gas Recirculation (EGR) valve location depends on the engine: the four-cylinder 2.2-liter (5S-FE) places the valve on the intake manifold toward the rear, while the six-cylinder 3.0-liter (1MZ-FE) locates the valve at the back of the engine near the firewall, fed by a metal tube from the exhaust. The valve is a small metal unit connected to vacuum hoses and a metal EGR pipe from the exhaust; identifying it is a matter of tracing those connections under the hood.
Engine-specific locations
Below are the typical locations for the two engine options offered in the 1997 Camry. Use these landmarks to guide your search under the hood.
4-Cylinder Camry (2.2L 5S-FE)
Where to look and how to recognize it:
- Location: Mounted on the intake manifold, toward the rear of the engine near the firewall, just above the throttle body.
- Appearance and connections: A small metal valve with two vacuum hose connections and a metal EGR tube feeding exhaust gas into the valve.
- How it’s fed: A curved EGR tube from the exhaust manifold connects to the valve; vacuum from the intake side operates it.
This configuration is common across many Camry 4-cylinder models of the era. If you can’t see it easily, trace the exhaust pipe that leads to the intake side of the manifold—the EGR valve is typically in that vicinity.
6-Cylinder Camry (3.0L 1MZ-FE)
Where to look and how to recognize it:
- Location: On the back side of the engine, near the firewall, attached to an intake passage; a metal tube from the exhaust manifold routes into the EGR valve.
- Appearance and connections: A compact valve with vacuum lines and, in many cars of this era, a nearby DPFE sensor that monitors EGR flow.
- How it’s fed: The exhaust gas enters through the EGR tube from the exhaust manifold; vacuum from the intake controls opening.
With the V6, the valve sits higher up and toward the rear of the engine compartment, so you may need to feel around near the driver’s side rear of the engine with the hood up to spot it.
What to do if you’re inspecting or servicing
Before removing components, ensure the engine is cool and the battery is disconnected if you’ll be working near electrical connectors. Use a flashlight to inspect for carbon buildup, and consider cleaning or replacing the EGR valve if you notice sluggish engine performance, rough idling, or check engine codes related to EGR flow. If you’re uncertain, consult a service manual for diagrams specific to your VIN and country, as layouts can vary slightly by production date and market.
Summary
The EGR valve location on a 1997 Toyota Camry depends on the engine: 2.2L four-cylinder engines place the valve on the intake manifold toward the rear near the firewall, while the 3.0L V6 positions it at the back of the engine near the firewall with a metal tube from the exhaust. Identification relies on a small metal valve with vacuum hoses and an adjacent exhaust-to-EGR tube. Always refer to a model-specific service diagram to confirm the exact placement for your car.
