Original fuel tank cap for Nissan Teana J31: articles and features

Original cover for Teana J31 has an article number 17202-4M000 (for models with a lock) or 17202-4M005 (without lock). These parts are manufactured by Nissan and guarantee 100% compatibility with the vehicle’s fuel system. However, the original is expensive - from 2,500 to 4,000 rubles, depending on the region. What are their advantages?

• 🔒 Tightness: The rubber seal seals out dust and moisture, preventing corrosion of the tank neck.
• 🔧 Precise fit: does not wobble and does not require modifications, unlike many analogues.
• 🚗 Sensor compatibility: does not cause errors P0455 (fuel vapor leak) or P0456 (low flow in vapor recovery system).
• 🔑 Reliable lock (in the version with a key): the mechanism rarely jams, unlike cheap replicas.

Gas tank cap analogues: what to choose instead of the original?

If the original cover is too expensive or is out of stock, you can find a worthy replacement. The main thing is to avoid “no-name” manufacturers, whose parts are often not sealed or quickly break. The table below shows proven analogues indicating article numbers and average prices (for 2026).

Brand	Article	Type	Average price, ₽	Features
Febi	22510	With lock	1 800–2 200	High-quality rubber, but the lock is less reliable than the original.
Denso	158-0109	Without lock	1 200–1 500	Lightweight, but the seal becomes dull over time.
Mannol	MN7202	Universal	800–1 000	Fits true to size but may require adjustment.
Patron	PCN17202	With lock	1 500–1 800	Good price/quality ratio, but the lock sometimes jams.

When choosing an analogue, pay attention to:

• 🔍 Seal material: It should be soft and elastic, without cracks.
• 🔑 Availability of a lock (if it was in the original): some analogues only come without a lock.
• 📏 Fit accuracy: The lid should fit tightly onto the neck without play.

⚠️ Attention! Cheap lids (price below 800 ₽) are often made of low-quality plastic that cracks at low temperatures. This may lead to dirt getting into the gas tank and fuel pump failure.

Problems with the gas cap Teana J31: diagnostics and solutions

Over time, the gas cap can become damaged. Let's look at typical problems and how to fix them.

1. The lid does not open (the lock is jammed)

If the key turns but the hatch does not open, the reason may be:

• 🔑 Frozen mechanism (relevant in winter). Solution: pour warm water or use a lock defroster.
• 🔧 Broken drive (the cable broke or came off). Solution: Remove the trunk trim and check the cable.
• 🛠️ Corrosion inside the lock. Solution: spray WD-40 and turn the key several times.

What to do if the key is broken in the lock?

If the key breaks off inside, do not try to pull it out with pliers - this will damage the mechanism. It is better to contact an auto electrician who will carefully drill out the cylinder. Temporary solution: open the hatch from the inside by bending the trunk trim (you need access to the cable drive).

2. The lid is not sealed (an error appears P0455)

Error P0455 (“Evaporative Emission System Leak”) often occurs due to:

• 🕳️ Cracks in the seal - replace the cover.
• 🔩 Loose fit — check if there is dirt on the neck.
• 🚫 Missing cover (for example, after refueling they forgot to close it).

⚠️ Attention! If you ignore the error P0455, this may lead to increased fuel consumption (up to 10%) due to loss of pressure in the tank and even damage to the adsorber.

3. The cover is lost or stolen

If the cover is missing, do not drive without it! This is fraught with:

• 💨 Dust and debris getting into the gas tank (can clog the fuel filter).
• 🚨 Possibility of fuel drainage by attackers.
• 🔥 Increased fire hazard (spark from static electricity).

Temporary solution: Cover the neck with tape or use a universal cap (such as Mannol MN7202). But remember: this is a short-term option!
