Parts for your 2017 Toyota Land cruiser-Knock sensor

2017 Toyota LandCruiser knock sensor — is it actually there?

For Australian and New Zealand–spec 2017 Toyota LandCruiser 200 Series running the 1VD‑FTV 4.5‑litre V8 turbo‑diesel, a conventional knock sensor isn’t fitted and isn’t required. That’s not a parts catalogue glitch — it’s how the engine management is designed.

Technical references back this up: Toyota’s Global Service Information (TIS) Repair Manual for the 200 Series lists a Knock Sensor system and diagnostics only for petrol 3UR‑FE engines, not for the 1VD‑FTV diesel. The Toyota New Car Features (NCF) manual for the 1VD‑FTV details all engine control sensors (crank and cam position, fuel pressure, MAF/MAP, EGT, intake air temp, coolant temp, accelerator position, etc.) with no knock sensor in the list. And the Toyota Electronic Parts Catalogue (EPC) for AU/NZ 2017 LandCruiser 200 shows no knock sensor assembly for 1VD‑FTV models, while petrol 3UR‑FE models (sold in other markets) do show two knock sensors on the block.

Why no knock sensor on the diesel? Classic “spark knock” detection isn’t needed on compression‑ignition engines. The 1VD‑FTV doesn’t time a spark, it controls combustion with pilot/main injection events, rail pressure and boost. The ECU uses crankshaft speed variation and injector feedback to balance cylinders, and it calibrates combustion noise via injection strategy. Given the naturally higher combustion noise of a diesel and the heavy V8 structure, an acoustic knock sensor wouldn’t provide meaningful control authority the way it does on petrol engines.

Worth noting for shoppers with private imports: 2017 LandCruiser 200s equipped with the 5.7‑litre 3UR‑FE petrol V8 (common in North America and the Middle East) do run a pair of knock sensors mounted on the valley of the block — that’s a different setup to local diesel vehicles.

Popular questions

Does a 2017 LandCruiser 200 diesel have a knock sensor?
On AU/NZ 1VD‑FTV diesel models, no. Toyota’s Repair Manual and NCF don’t include a knock sensor for this engine, and the local EPC doesn’t list one as a service part.

Which 2017 LandCruiser models do use a knock sensor?
Petrol‑engined 3UR‑FE versions (sold in markets like North America and the Middle East) use two knock sensors on the engine block. If someone owns a petrol import, that’s the configuration they’ll have.

I’ve got a P0325 or P0330 code on my 2017 LandCruiser — is that the knock sensor?
Those codes refer to knock sensor circuits on petrol engines. If the vehicle is a 1VD‑FTV diesel, a generic scan tool profile might be mislabelling the fault. It’s best to confirm the engine code (on the VIN plate) and re‑scan with Toyota‑specific diagnostics.
