Parts for your 2016 Toyota Crown-Ignition coils

2016 Toyota Crown ignition coils: what they do and how to look after them

The 2016 Toyota Crown absolutely uses ignition coils. All its petrol and petrol-hybrid engines of the S210 generation — including the 2.0L turbo 8AR‑FTS, the 2.5L hybrid 2AR‑FSE and the 3.5L V6 hybrid 2GR‑FSE — run a coil‑on‑plug Direct Ignition System (DIS). This is documented in Toyota New Car Features (NCF) and Repair Manual coverage for these engines, and the Toyota Electronic Parts Catalogue for the S210 Crown lists individual ignition coil assemblies for each cylinder. So yes, ignition-coils are relevant, fitted, and vital to how this Crown runs.

The job of the ignition coil is simple but crucial: it transforms the 12‑volt supply into the high voltage needed to jump the spark plug gap, lighting off the air–fuel mix cleanly. With a dedicated coil on each plug, the Crown gets sharper timing control, stronger spark energy and better efficiency compared to older distributor systems — which is exactly what you want for smooth cruising and tidy fuel economy.

As part of regular servicing, coils don’t have a fixed replacement interval, but they do appreciate a bit of attention. At major services (around every 40,000–60,000 kilometres), it’s smart to inspect coil boots for cracking, check for oil in the plug tubes, and confirm there are no corrosion issues at the terminals. Coils tend to be “on‑condition” items: replace when there are symptoms or fault codes. Typical red flags include:

• Misfire under load or at idle, rough running, hesitant acceleration
• Higher fuel use, a sulphur smell from the exhaust, lack of power
• Check Engine Light with codes like P0300–P0306 or P0351–P0356

When replacing a coil, let the engine cool, remove the engine cover, unplug the connector and take out the small retaining bolt. Lift the coil, inspect the boot, and if the spark plug is due (often 60,000–100,000 km depending on plug type and engine), do both together. Apply a tiny dab of dielectric grease to the inside of the boot, refit the coil and tighten to the factory spec. Stick with quality, OE‑equivalent parts and avoid mixing odd brands across cylinders.

Hybrid models still use standard 12V coil-on-plug units on the petrol engine. There’s no need to touch the high‑voltage system for coil or spark plug work, but normal hybrid safety procedures should always be followed under the bonnet.

Popular questions about 2016 Toyota Crown ignition coils

How many ignition coils does a 2016 Toyota Crown have?
The 2.0L turbo and 2.5L hybrid variants have four coils (one per cylinder). The 3.5L V6 hybrid has six coils. If unsure which engine is under the bonnet, the build plate and engine cover will give it away.

When should the ignition coils be replaced?
There’s no fixed interval. They’re replaced on condition — usually when misfires appear or codes are logged. During major services, have them inspected and plan coil replacement alongside spark plug changes if age, heat or oil contamination has taken a toll.

Is it okay to replace just one coil?
Yes, on these Crowns it’s fine to replace a single failed coil. If several coils are the same age and misfires start popping up across different cylinders, it can be more cost‑effective to replace the affected set, and always fit a fresh spark plug in the misfiring cylinder.
