Replace the EGR valve on a 2012-2017 Toyota Camry 2.5L I4 engine to restore proper exhaust gas recirculation and resolve related engine performance issues.

Warnings

Tools required

Parts

• EGR valve × 1 — Use OEM specification
• EGR valve gasket × 1 — Use OEM specification
• EGR tube gasket × 1 — Use OEM specification

Preparation

1. Ensure engine has been off for at least 2 hours and is completely cool to the touch
2. Disconnect negative battery terminal and wait 3 minutes
3. Remove engine cover by pulling upward on the four corners to release clips
4. Locate EGR valve on the intake manifold near the firewall on the driver side

Procedure

1. 1

   Disconnect EGR valve electrical connector
   Press the tab on the EGR valve electrical connector and pull straight away from the valve body to disconnect. Move the wiring harness aside to provide clearance.
2. 2

   Remove EGR valve cover
   Remove the two cover screws securing the EGR valve cover using a 10mm socket. Lift the cover off and set aside. Note the orientation of any insulators or heat shields.

   Cover Screws11 Nm (8 lb-ft)
3. 3

   Disconnect EGR tube fitting
   Using a 14mm socket, loosen and remove the EGR tube fitting that connects the EGR cooler to the EGR valve. The tube may have carbon buildup making it stiff. Support the tube while removing the fitting to prevent damage.
   Torque spec

   EGR Tube Fitting35 Nm (26 lb-ft)
4. 4

   Remove EGR valve mounting bolts
   Using a 12mm socket with extension, remove the two EGR valve bolts securing the valve to the intake manifold. The lower bolt may be difficult to access and require a long extension. Keep track of any spacers or washers.

   EGR Valve Bolts25 Nm (18 lb-ft)
5. 5

   Remove EGR valve assembly
   Carefully pull the EGR valve away from the intake manifold. The valve may be stuck due to carbon buildup. Gently wiggle while pulling to break the seal. Remove and discard the old gasket from both the valve and manifold mating surface.
6. 6

   Clean mating surfaces
   Use a gasket scraper and wire brush to thoroughly clean the intake manifold EGR mounting surface. Remove all carbon deposits and old gasket material. Wipe clean with a shop towel. Ensure no debris falls into the intake manifold opening.
   ⚠Cover the intake manifold opening with a clean towel while cleaning to prevent debris from entering the engine.
7. 7

   Install new gasket and EGR valve
   Position the new EGR valve gasket onto the intake manifold. Align the new EGR valve with the mounting holes and gasket. Hand-thread both mounting bolts to prevent cross-threading before tightening.
8. 8

   Torque EGR valve bolts
   Using a torque wrench, tighten the two EGR valve bolts in a cross pattern to the specified torque. Start with the upper bolt, then the lower bolt, ensuring even pressure on the gasket.

9. 9

   Reconnect EGR tube
   Install a new EGR tube gasket if applicable. Position the EGR tube to the valve and hand-thread the fitting. Using a torque wrench with 14mm socket, tighten the EGR tube fitting to specification.

   EGR Tube Fitting35 Nm (26 lb-ft)
10. 10

    Reinstall EGR valve cover
    Position the EGR valve cover and any heat shields or insulators in their original orientation. Install the two cover screws and torque to specification using a torque wrench.

11. 11

    Reconnect electrical connector
    Push the electrical connector firmly onto the EGR valve until you hear and feel a positive click. Gently tug to verify it is fully seated and locked.

Reassembly

1. Reinstall engine cover by aligning clips and pressing down firmly at all four corners until seated
2. Reconnect negative battery terminal and tighten securely
3. Clear any stored diagnostic codes using an OBD-II scanner if available

Verification

• Start the engine and verify it idles smoothly without rough running or stalling
• Listen for any exhaust leaks or hissing sounds near the EGR valve area
• Allow engine to reach operating temperature and verify no check engine light appears
• Test drive vehicle and confirm normal acceleration and no hesitation under load
• Use an OBD-II scanner to verify no EGR-related fault codes are present after driving for 10-15 minutes
