Parts for your 2014 Nissan Pathfinder-Ignition coils

2014 Nissan Pathfinder Ignition Coils

Per Nissan technical literature, ignition coils are absolutely fitted to the 2014 Nissan Pathfinder (R52). The Nissan Factory Service Manual (R52, 2014) — Engine Control (EC), Ignition System, specifies a coil-on-plug setup, and the Nissan electronic parts catalogue lists individual coil packs for both the 3.5L V6 VQ35DE (six coils) and the 2.5L supercharged hybrid QR25DER (four coils). So ignition coils are relevant to servicing and reliability on this model.

On this Pathfinder, ignition coils sit directly on top of each spark plug. Their job is to step up the battery’s 12 volts to the many thousands of volts needed to fire the plugs cleanly under load. Healthy coils mean crisp starts, smooth idle, decent fuel economy and lower emissions. When a coil gets tired, drivers often notice a rough idle, hesitation under acceleration, poorer fuel use and a flashing or steady check-engine light with misfire codes (P0300–P0306 on the V6, P0300–P0304 on the hybrid).

Coils aren’t a routine replacement item like spark plugs, but they do age from heat and vibration. As a rule of thumb, spark plugs are replaced at long intervals (often around 160,000 km for iridium, or as per the owner’s manual). Coils are replaced if they fail testing or show symptoms. On the V6, the front-bank coils are easy, the rear bank is tighter for access. The hybrid’s four coils are straightforward once the engine cover is off. If one coil fails on a high‑kilometre vehicle, many workshops test the remainder and may recommend replacing the affected side/bank to avoid repeat visits.

• Always scan for codes and confirm with a coil stress or swap test before replacing.
• Disconnect the battery, remove the engine cover, and label connectors to avoid mix-ups.
• Inspect coil boots for carbon tracking, replace any cracked boots and use a light smear of dielectric grease.
• Check for oil in plug tubes (often a rocker cover gasket issue) which can kill new coils if not fixed.
• Refit coil bolts to the manufacturer’s torque, don’t overtighten.
• After refit, clear codes and road-test under load to confirm the misfire’s gone.

Using quality OEM-equivalent coils keeps the Pathfinder happy and avoids chasing intermittent misfires. If the check-engine light’s on or there’s a stumble when towing or climbing, a quick ignition system check is well worth it.

How many ignition coils does a 2014 Nissan Pathfinder have?

The V6 petrol (VQ35DE) has six individual coil-on-plug units—one per cylinder. The 2.5L supercharged hybrid (QR25DER) has four coils. Both variants use individual coils rather than a single remote coil pack.

What are common symptoms of a failing ignition coil on this model?

Typical signs include a rough idle, hesitation on take-off, a noticeable shudder under load, higher fuel use and an illuminated check‑engine light with misfire fault codes. If left, a persistent misfire can damage the catalytic converters, so prompt diagnosis is smart.

Should all coils be replaced at once?

Not necessarily. Many techs replace only the faulty coil after confirming with a scan and swap test. On high‑kilometre vehicles, it can be sensible to replace the same bank or the full set to reduce future visits, especially if multiple coils test weak.
