🔧 Camry - Fuel Cap Replacement

Your fuel cap seals the fuel system so fuel vapors don’t leak out. A worn or missing cap can trigger a Check Engine Light (often for an EVAP leak) and may cause a fuel smell.

Difficulty Level: Beginner | Estimated Time: 0.1-0.3 hours

⚠️ Safety & Precautions

• ⚠️ Work outdoors or in a well-ventilated area; fuel vapors are flammable.
• ⚠️ No smoking, flames, or sparks near the fuel door.
• ⚠️ Don’t top off the tank after the pump clicks off; it can damage the EVAP system.
• ⚠️ Let the car cool if you just drove; avoid hot exhaust areas.
• ⚠️ Battery disconnect is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Use your hand to open the fuel door on the left rear side.
• Put on nitrile gloves and safety glasses.

Step 2: Remove the old fuel cap

• Turn the cap counterclockwise by hand until it comes free.
• If the cap is tethered (a small strap that keeps it from getting lost), let it hang or place it in the cap holder if your filler door has one.

Step 3: Inspect and clean the sealing area

• Use a clean shop towel to wipe the rim of the filler neck (the round metal/plastic opening).
• Check the old cap’s rubber seal for cracks or flattening. Bad seal = EVAP leak codes.

Step 4: Transfer/attach the tether if needed

• If your new cap doesn’t include the tether, carefully move it over.
• Use a small flat trim tool to gently pop the tether clip free if it’s clipped to the cap. A trim tool is a small plastic pry tool that helps prevent scratches.
• Attach the tether to the new cap the same way it was on the old one.

Step 5: Install the new fuel cap

• Thread the new cap on by hand clockwise.
• Tighten until it clicks securely (typically at least 1 click).
• Do not use tools to tighten the cap—hand-tight only.

Step 6: Close the fuel door

• Close the fuel door firmly with your hand.
• Wipe any fuel residue with a clean shop towel.

✅ After Repair

• Start the car and confirm there’s no fuel smell around the fuel door.
• If you had a Check Engine Light for an EVAP leak, it may take a few drive cycles to turn off on its own after the fix.
• If the light stays on, the issue may be a different EVAP leak (hose, purge valve, vent valve), not the cap.
