Parts for your 2013 Toyota Camry-Fuel cap

2013 Toyota Camry fuel cap – what it does and when to replace it

Based on Toyota’s technical literature for the XV50-series Camry (2012–2017), including the 2013 Owner’s Manual “Fuel tank cap” guidance and Toyota service information for the EVAP (evaporative emissions) system, this model uses a conventional, tethered screw-on fuel cap. It’s not a capless design. The manual specifically instructs tightening the cap until it clicks, and Toyota diagnostics list a loose or deteriorated cap as a common cause of EVAP leak faults. That confirms a fuel cap is relevant and fitted on the 2013 Toyota Camry.

On the 2013 Camry, the fuel cap quietly does a lot of heavy lifting. It seals the filler neck so petrol fumes don’t escape, keeps dust and water out of the tank, and helps the EVAP system hold the right pressure so the car meets emissions rules. Get it wrong and the dash can light up with a Check Engine lamp, fuel smells can creep in, and economy can suffer.

Servicing-wise, it’s a small part worth a quick look at every scheduled service. Owners can check the rubber sealing ring for cracks or flattening, make sure the tether isn’t broken, and confirm the cap tightens until it clicks several times. If there’s a whiff of fuel around the rear guard, or the vehicle throws EVAP codes like P0440–P0457 after refuelling, the cap is the first suspect. Re-seat it, drive a few trips, and if the light stays on, consider replacement or a smoke test of the EVAP system.

When replacing, stick with a genuine-spec vented Toyota cap designed for the XV50 Camry (petrol and Hybrid use a standard threaded cap). Universal caps or poorly matched locking caps can upset EVAP pressure and cause nuisance faults. Fit the new cap clean and dry—no grease or sealant needed. If the filler neck lip is dirty, wipe it before installing. After refuelling, don’t overfill past the first click of the pump, overfilling can saturate the charcoal canister and mimic cap issues.

Signs it’s time for a new cap include: persistent fuel odour, visible cracks in the seal, a cap that no longer “clicks,” or recurring EVAP leak codes. In Aussie and Kiwi conditions—heat, dust, and plenty of kilometres—a cap can harden over the years. There’s no fixed interval, but many workshops treat a cap as preventative maintenance if it shows wear from about the five-to-10-year mark.

• Key benefits: keeps fumes in, dirt and water out, and the EVAP system happy
• Quick check: intact seal, firm clicks on tightening, no fuel smell
• Best practice: use a Toyota-spec cap, avoid cheap universals

Popular questions about 2013 Toyota Camry fuel caps

What fuel cap type fits a 2013 Camry?

The 2013 Camry (XV50) takes a Toyota-spec vented, threaded cap with a tether. Genuine or OEM-equivalent caps are recommended for correct EVAP operation. Locking versions are available, but they must be listed as compatible with the XV50 Camry. Hybrid models use the same style cap as the petrol variants.

Why does the Check Engine light come on after refuelling?

A loose or failing cap is the most common reason. If the cap isn’t clicked tight, the EVAP monitor sees a leak and can log codes like P0455 or P0457. Tighten until it clicks several times and drive a few trips, if the light persists, the seal may be worn or there may be another EVAP leak that needs a workshop check.

How often should the fuel cap be replaced?

There’s no strict interval. Inspect it at each service and replace if the rubber seal is cracked, the cap won’t click, there’s a persistent fuel smell, or EVAP codes keep returning. In Australian and New Zealand conditions, many owners end up replacing a tired cap somewhere around the five-to-10-year mark.
