Parts for your 2017 Nissan Serena-Ignition coils

2017 Nissan Serena ignition coils

Yes, the 2017 Nissan Serena uses ignition coils. Nissan’s C27 Serena Service Manual (EC/Engine Control System) specifies a coil-on-plug ignition system for the MR20DD 2.0‑litre petrol S-HYBRID engine, and Nissan’s FAST parts catalogue and major OE suppliers’ catalogues (DENSO/Hitachi) list individual ignition coils for the C27 Serena. That makes ignition coils clearly relevant to this model year.

On the 2017 Serena, each cylinder gets its own coil mounted directly on the spark plug. The job of an ignition coil is to take the 12V from the battery and step it up to the high voltage needed to fire the spark plug under compression. With the Serena’s coil-on-plug setup, you get strong, precise sparks, cleaner running, and fewer high-tension leads to fail.

There’s no fixed replacement interval for ignition coils on this model, but they work hand‑in‑hand with the spark plugs. When the Serena is due for new iridium plugs (typically around the 100,000 km mark, per Nissan schedules), it’s a good time to inspect the coils. Look for cracking, heat discolouration, oil in the plug wells from a cam cover leak, or brittle connectors. If the van’s showing a rough idle, sluggish take‑off, poor fuel economy, or the check engine light with misfire codes (P0300–P0304) or coil circuit codes (P0350‑series), a weak coil could be the culprit.

Replacement is straightforward: remove the engine cover, disconnect the negative battery terminal, unplug the coil connector, undo the retaining bolt, and lift the coil straight up. Avoid yanking on the wiring. If one coil has failed at higher kilometres, many techs recommend replacing the full set on the MR20DD to keep things even, though targeted replacement after swap‑testing is also common. Use quality OE‑equivalent coils and ensure the spark plug wells are clean and dry before refitting.

For preventative care, keep to the recommended plug change interval, fix any rocker cover gasket seepage early, and avoid washing the engine bay aggressively—water in the plug tubes is hard on coils. A quick scan with an OBD tool during regular servicing helps catch a weak coil before it leaves the family stranded on a road trip across Aotearoa or out in regional Australia.

• Common symptoms of a failing coil: hard starts, misfire at idle or under load, hesitation, and increased fuel use.
• Best practice: inspect coils at every major service and whenever plugs are replaced.

Does the 2017 Nissan Serena definitely have ignition coils?
Yes. The C27 Serena’s MR20DD petrol engine uses a coil‑on‑plug ignition system. This is documented in Nissan’s C27 Serena Service Manual (EC section) and reflected in Nissan FAST and OE supplier parts listings for the model.

How often should the coils be replaced?
There’s no set kilometre interval. Coils are replaced when faulty or when inspection shows damage. Check them whenever you replace the iridium spark plugs (around 100,000 km) or if you’re chasing misfire fault codes.

Can a single bad coil be replaced on its own?
Absolutely. If diagnostics confirm one weak coil, you can replace just that unit. On higher‑kilometre vehicles, some owners choose to replace all coils at once for long‑term reliability, but it’s not mandatory.
