Parts for your 2022 Toyota Land cruiser-Ignition coils

2022 Toyota LandCruiser 300: Are ignition coils used?

For Australia and New Zealand, the 2022 Toyota LandCruiser 300 Series (LC300) is delivered exclusively with the 3.3‑litre twin‑turbo V6 diesel (engine code F33A‑FTV) and a 10‑speed auto. That specification is confirmed in Toyota Australia’s model specifications and owner literature for the LC300, which describe diesel‑specific systems such as glow plugs and high‑pressure common‑rail injection, and make no provision for spark‑ignition components like ignition coils. Diesel engines operate by compression ignition rather than a spark, so there are no ignition coils fitted on AU/NZ LC300 models. Technical references supporting this include the Toyota Australia LC300 specification sheets (2022), the LC300 owner’s manual sections on diesel starting/glow plug operation, and Toyota Global’s model briefing detailing the F33A‑FTV diesel for markets like Australia and New Zealand.

Because the LC300 diesel doesn’t need a spark to ignite the air‑fuel mix, it doesn’t use coils, spark plugs, or conventional ignition leads. Instead, it relies on:

• High compression and turbocharging to heat air in the cylinders
• Precise electronic fuel injection via a common‑rail system
• Glow plugs to aid cold starts

That’s why “ignition‑coil” issues don’t apply to the 2022 LandCruiser diesel. If the vehicle ever feels like it’s “misfiring”, the usual culprits are diesel‑specific, such as an injector problem, a boost or vacuum leak, EGR fouling, DPF regeneration behaviour, or a fuelling/filtration issue. Regular servicing per Toyota’s schedule—fresh fuel filters, quality diesel, correct oil spec, and timely air‑filter changes—keeps the combustion clean and the engine smooth. Battery health also matters for strong cranking and glow‑plug performance, especially in colder climates.

A quick note for owners of imported or non‑AU/NZ LC300s: some markets offer a 3.5‑litre twin‑turbo petrol V6 (engine code V35A‑FTS). That petrol variant uses coil‑on‑plug ignition (one coil per cylinder). If someone has the petrol LC300, coil inspection and replacement becomes relevant, however, for Australian and New Zealand‑delivered 2022 LandCruiser 300s, ignition coils aren’t fitted or serviced.

FAQs

Does the 2022 LandCruiser 300 in Australia have ignition coils?

No. The AU/NZ LC300 runs the 3.3‑litre twin‑turbo diesel V6, which uses compression ignition and glow plugs rather than spark ignition. Toyota’s local specs and owner information list diesel systems only—there are no ignition coils to replace or maintain on these vehicles.

What should be checked if the LC300 diesel feels like it’s misfiring?

On a diesel, “misfire‑like” symptoms usually point to fuel, air, or emissions hardware. Start with the basics: clean fuel and air filters, check for boost leaks, and scan for fault codes. Injector performance, EGR deposits, and DPF regeneration behaviour are common contributors. A battery or glow‑plug issue can also cause rough cold starts.

If importing a petrol LC300, how often do ignition coils need attention?

Petrol LC300s (V35A‑FTS) use six coil‑on‑plug units. Coils aren’t a routine replacement item and are typically changed only if there’s a fault (misfire codes, rough running). Good practice is to inspect connectors and boots during spark‑plug services and replace coils in pairs or sets if age‑related failures begin to show.
