This procedure covers the removal and replacement of the EVAP vent valve (canister vent shut valve) on a 2018-2024 Toyota Camry with the 2.5L I4 engine.

Warnings

Tools required

Parts

• EVAP vent valve (canister vent shut valve) × 1 — 90910-12264 or equivalent OEM
• Vapor hose clamps (if damaged) × 2 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Turn ignition off and remove key from vehicle
3. Allow engine to cool if recently driven
4. Disconnect negative battery terminal and wait 3 minutes to clear airbag system capacitors

Procedure

1. 1

   Remove rear seat cushion
   From inside the vehicle, locate the two retaining clips at the front edge of the rear seat cushion. Firmly pull upward on the front edge of the seat cushion to disengage the clips, then lift and remove the cushion from the vehicle to access the rear cargo area floor.
2. 2

   Access rear cargo floor panel
   Open the trunk and remove the trunk floor mat. Locate and remove the rear cargo floor panel by lifting it from the rear of the trunk. This panel is typically held by clips and does not require tools. Set aside carefully to avoid breaking clips.
3. 3

   Locate EVAP vent valve assembly
   The EVAP vent valve is mounted on the left (driver) side of the fuel tank area, accessible from the trunk. It is a black cylindrical component approximately 3 inches long with an electrical connector and two vapor hoses attached. It may be mounted to a bracket near the charcoal canister.
4. 4

   Disconnect electrical connector
   Press the locking tab on the electrical connector and pull straight away from the EVAP vent valve. Do not pull on the wires themselves. If the connector is stubborn, gently rock it side to side while pulling.
5. 5

   Disconnect vapor hoses
   Using needle nose pliers, carefully squeeze and slide the hose clamps away from the valve connection points on both vapor hoses. Once clamps are moved, firmly grip each hose close to the valve and twist while pulling to remove. Note the orientation of each hose for reinstallation.
   ⚠Fuel vapor odor will be present when disconnecting hoses. Ensure adequate ventilation.

6. 6

   Remove mounting fastener
   The EVAP vent valve is secured to its bracket with a single 10mm bolt. Use a 10mm socket to remove this bolt completely. Support the valve while removing the bolt to prevent it from falling.
   Torque spec

   Mounting Bolts27 Nm (20 lb-ft)
7. 7

   Remove EVAP vent valve
   Carefully withdraw the EVAP vent valve from its mounting location. Inspect the mounting bracket for damage or corrosion. Check both vapor hose connection points on the valve for cracks or damage.
8. 8

   Install new EVAP vent valve
   Position the new EVAP vent valve into the mounting bracket, ensuring proper orientation with the electrical connector facing the correct direction for easy connection. The valve outlet ports should align with the vapor hoses.
9. 9

   Install mounting bolt
   Thread the 10mm mounting bolt by hand first to ensure proper thread engagement. Once hand-tight, use a torque wrench to tighten to specification.

10. 10

    Connect vapor hoses
    Push each vapor hose firmly onto the corresponding valve port until fully seated. You should feel a positive engagement. Slide the hose clamps back into position over the connection points, positioning them approximately 10mm from the end of each hose. Tighten clamps to specification using a torque wrench with appropriate adapter.

11. 11

    Connect electrical connector
    Align the electrical connector with the valve terminal and push firmly until you hear or feel a distinct click. Gently tug on the connector to verify it is fully locked in place.
12. 12

    Reconnect battery and clear codes
    Reconnect the negative battery terminal. Start the vehicle and allow it to idle. Use an OBD-II scanner to clear any EVAP-related diagnostic trouble codes (DTCs) that were stored. The check engine light should turn off after codes are cleared.

Reassembly

1. Reinstall the rear cargo floor panel, ensuring all clips engage properly
2. Replace trunk floor mat in original position
3. Reinstall rear seat cushion by aligning the rear hooks first, then pressing down firmly on the front edge until both clips engage with an audible click
4. Verify rear seat cushion is securely fastened before allowing passengers

Verification

• Start the engine and verify no check engine light is present
• Listen for any abnormal hissing sounds from the EVAP vent valve area that might indicate a vacuum leak
• Perform an EVAP system test using an OBD-II scanner with active test capability, commanding the vent valve open and closed to verify proper operation
• Monitor for DTCs P0441, P0446, P0455, or P0456 which would indicate EVAP system issues
• Drive the vehicle through at least one complete drive cycle to allow the EVAP monitor to run and verify repair success
